I now have further information about a couple of other boats: 45 Medium-sized powerboat (as I recall), used a good deal. The "Access" item may be "accessories"_I cannot recall. Payment Fuel Repair Maint Access Moor Insur TOTALS March $284 $251 $10 $343 $470 $120 $25 $1,503 April $284 $262 $882 $240 $1,687 $120 $25 $3,500 May $284 $218 $3,905 $18 $71 $120 $25 $4,641 June $284 $384 $0 $8 $126 $120 $25 $947 July $284 $838 $34 $4 $106 $120 $25 $1,411 Aug $284 $94 $119 $39 $232 $145 $25 $938 Sept $284 $395 $0 $3 $19 $145 $25 $871 Oct $284 $0 $0 $18 $0 $145 $25 $472 Nov $284 $92 $17 $0 $0 $145 $25 $563 Dec $284 $141 $0 $0 $0 $145 $25 $595 Jan $284 $0 $0 $55 $359 $145 $25 $868 Feb $284 $335 $9 $371 $13 $145 $25 $1,182 ------------------------------------------------------------------------ TOTALS $3,408 $3,010 $4,976 $1,099 $3,083 $1,615 $300 ANNUAL TOTAL $17,491 AVERAGE MONTHLY $1,458 ________________________________________________________________________ And for another sailboat: We're under $1,000 a month for a 39' sailboat at the Shilshole Bay Marina in Seattle. And one more: I don't have monthly totals, but the following are my yearly totals for a 22' commercial dory with an 88 h.p. outboard ... Licensing fees: Fish and Wildlife 450.00 NOAA Marine mammal exemption 30.00 F.C.C. Operators license 35.00 _______ total: $550.00 Maintenance and upkeep: $2884.50 total fuel consumption: 534.6 gallons $787.22 total tackle expenses $825.32 46 _________ Grand total: $5047.04 I fished the boat an average of three days a week (some weeks more, others less) and I grossed $3372.06 last year. That brought my total expenditure for eight months of fishing (and boating on the Pacific) to about $2700. That gives me a monthly average of about $225/month. My insurance (for an ocean going commercial fishing vessel) was $236 for 1992. That will go up to $242 this year. And one more: OK, how's this for cheap: A friend of mine and I bought a used DaySailer for somewhat less than $3000 last summer and during the fall sailing season, we spent less than $300 total on maintenance, which included a new battery for our trolling motor, various rigging upgrades, a new trailer wheel, grease for the trailer wheels, and a new anchor. We've spent $70 pre-season this year for a reef point and other than new bearings on the trailer, we're ready to go. OK, so we don't do blue-water sailing, but it gets us out on the water on the weekends. :-) And another detailed one from William Courington: I can hardly believe I'm doing this in public, the numbers are so sobering. But here's the cost for Lively in 1993. She's is a modified Olson30 sailboat in San Francisco, maintained to a pretty high standard by an owner who generally values convenience/quality/time over cost. This year's major optional expense was revarnishing the interior. (Eleven years old, and quite thin, it wasn't *that* optional-especially considering that birch ply turns black when it gets wet.) Unlike the three previous years there were no new sails, no new engine, no new rigging to speak of. Maybe a typical year in the life of a sailboat. Note how a few big items dominate each category. Grand Total $8700.62 Maintenance Total $4823.61 Major Items Engine Service 434.13 By pros Bottom Paint Job 1001.39 By yard Monthly Bottom Clean 261.20 By pro 47 Interior Varnish Job 2473.41 By pros Ext.

Of Total 87% Let me also add a remark from Mike Hughes: People waste time, effort and money on all kinds of things that don't make sense when by owning a boat one can consolidate and waste them all on one thing. Think about that before you ever consider owning a boat as an investment. Two more interesting facts on this whole issue: Some years ago I plotted (length, price) for 200 used fiberglass sailboats (19-50ft) on log-log paper and found a pretty good straight line (scatter was about a factor of 2 in price). The plot indicated that the price varied as the 3.6 power of the overall length. It implies that a factor of 2 in length is about a factor of 10 in price. (pk). I'm surprised nobody has mentioned this, but sailboats, like any other precious commodity, are sold per unit of mass, not size. My rule of thumb is that new fiberglass sailboats cost $10 per pound displacement. This holds (relatively) true from 12 feet to 90 feet. This does not generate accurate numbers, but gets you in the ballpark. (tf) 48 5.7 Who can tell me about boat X? Various people on the net know about their own boats and seem to be willing to talk.

The FCC form order answering machine is (202) 418 36766 and the human operated info line is (202) 632 3337. Call these numbers to get info about getting a VHF license. (dk1) You can learn about operating procedures for your VHF radio from Chapman's (see the bibliography). One essential rule: Channel 16 is for commercial hailing and distress calls. Hailing by recreational vessels is now supposed to happen on Channel 9. You are required to carry adequate saftey devices for your boat. What is deemed adequate varies by size. Most marine stores have a pretty good idea what's the minimum. Once again, Chapman's can give you details. There are no "licenses" for boating in the US_you can buy the biggest, fastest boat on earth and do whatever you want with it, as long as it's recreational and you do not carry passengers or freight for hire, and you abide by the various marine laws that apply. Prudence dictates that you should learn how to operate your vessel before you start out. Note that many states have begun enforcing Boating While Intoxicated laws, and that some have begun enforcing speed limits. See the additional material below. If you want to operate a marine radio from your boat, you need a station license. Generally a license application is packaged with each radio set, and all radio dealers carry applications. If you are licensing any marine radios, the first will be a VHF set for "local" communications ( <30 miles) with 2-25 watt output. Marine radios must be "type accepted" which means you can not build it yourself, or modify a CB, commercial, or ham set. Pleasure boaters do not need a radio operator's license. (wv) 50 In general, boat registration laws and fees vary from state to state. Usually a boat dealer or the local state police detachment is a good starting point for specifics. (wv) To carry any passengers for hire you need a Coast Guard license. Before you can even take the required written exam(s) you need documentary evidence of a full year (365 days) of boating experience. Licenses come in several categories. To carry more than six passengers for hire, the boat must also be inspected by the Coast Guard. Fines for violations are quite high. (wv) Courtesy of Terry Steinford, we have the following long and thorough essay about carrying passengers, etc.: (tls@gate.net) Some of the requirements for carrying passengers, chartering and licensing were changed about a year ago. Self-propelled vessels that carry any passengers for hire are required to be operated by a Coast Guard licensed operator. If the vessel carries more than 6 passengers, at least one of which is a passenger for hire, the vessel is required to be inspected by the Coast Guard as a commercial passenger vessel. A pure sail vessel under 100 gross tons carrying up to 6 passengers is not required to have a licensed operator. Way back in ancient history, pure sail vessels up to 700 gross tons carrying passengers were not required to be inspected, but that loophole was eliminated years ago. The minimum license is the Operator of Uninspected Passenger Vessels (OUPV), formerly known as the Motorboat Operator or 6-pack license. Inspected vessels require a licensed Master with the appropriate tonnage and geographical route. All OUPV licenses are valid for vessels up to 100 gross tons. The "near coastal" route is up to 100 miles offshore. "Inland" is most waters that are a lake, bay or sound on a chart. The dividing line between near coastal and inland is based on geography, not the rules of the road. On December 20, 1993 the President signed the Passenger Vessel Safety Act of 1993 (public law 103-206), changing the legal requirements for passenger and charter operations. The act establishes for the first time the definition of passenger for hire and requires many vessels operating under bareboat charter to be inspected by the Coast Guard as commercial passenger vessels. The law also changes the inspection requirements for certain vessels over 100 gross tons. The new law has relaxed the prior strict treatment of situations were a 51 guest provided food or chipped in for expenses. Previous law treated such such guests as passengers, requiring operator licenses and possibly vessel inspection. Under the new law a passenger for hire is is a passenger for whom consideration is contributed as a condition of carriage on the vessel, whether directly or indirectly flowing to the owner, charterer, agent or any other persons having an interest in the vessel. Consideration is an economic benefit, inducement, right or profit including pecuniary payment accruing to an individual, person, or entity, but not including a voluntary sharing of the actual expenses of the voyage by monetary contribution or donation of fuel, food, beverage or other supplies. Previously, vessels operating under legitimate bareboat or demise charters were not required to meet the commercial passenger vessel standards. Some vessels operating under charter are carrying hundreds of persons and are in direct competition with commercial passenger vessels meeting the Coast Guard inspection and licensing requirements. Under a legitimate bareboat charter the vessel is in essence "sold" to the charterer for the duration of the charter, hence the people carried aboard were not passengers for hire. In some cases the charterer may not have been aware of his legal liabilities during the charter. Unsuspecting passengers may not have been aware that they were sailing on a vessel that did not meet the same safety equipment and design standards as a regular passenger vessel. Congress has acted to remove these differences for charter vessels carrying more than 12, or in some cases 6 passengers. The following vessels are required to be inspected by the Coast Guard: (1) if under 100 gross tons: (a) carrying more than 6 passengers, including at least 1 for hire, or (b) chartered with crew provided or specified by owner and carrying more than 6 passengers, or (c) chartered and carrying more than 12 passengers, or (d) submersible vessels carrying 1 or more passengers for hire (2) if 100 gross tons or over: (a) carrying more than 12 passengers, including at least 1 for hire, or (b) chartered and carrying more than 12 passengers, or (c) submersible vessels carrying 1 or more passengers for hire 52 An uninspected vessel that carries not more than 6 passenger for hire is required to carry the safety equipment in Subchapter C of Tile 46 of the Code of Federal Regulations. The requirements are generally the same as for a recreational vessel of the same length, except that all life jackets must be Type I commercial style. There are no federal requirements for insurance for these vessels. Local government agencies may require business or occupational licenses, including insurance or bonds. 5.9 What's a formula for top speed? The answer, verbatim from mp, is: The formula yacht designers use is called Crouch's formula. It takes into account the weight and horsepower at the propeller, and assumes a 50"% to 60"% efficient prop. Most props fall into this range. Note that it doesn't take into account the boat length, as that doesn't matter with planing boats. Crouch's Formula V = C/((DISP/HP)**.5) Where V = boat speed in knots (1 knot=1.15 mph) C = Constant (depends on boat type) DISP = Displacement (pounds) Note that boat manufacturers usually give innacurate numbers for displacement, typically on the low side HP = Horsepower available at the propeller For comparison sake, here are some average values of C: 150 Typical lightweight, planing cruiser 180 High Speed Runabout 200-230 Race boats, hydroplanes etc. 53 5.10 Accurate time source for navigation The time of day is broadcast on radio stations WWV and WWVH, which transmit in the shortwave bands, on 2.5, 5, 10, 15, 20 MHz. The time is announced every minute, and at other times there is a steady beeping. Any shortwave receiver should be able to pick up these broadcasts - the particular frequency you can receive will vary with location and time of day. You can also hear the NIST's WWV broadcasts via the telephone. The number is (303) 499-7111. 5.11 Winter storage for batteries, and their state of charge There is a ritual debate on this topic each year. The concensus seems to be that (1) It's OK to store a battery on a cement floor, but if you stick it on an old piece of plywood, any drips or spills will be easier to clean up, so perhaps the old wives' tale has some value, (2) storing a battery cold in the winter, provided it is fully charged, is an OK thing to do. The rate of discharge is reduced by the cold environment, so less frequent recharging is called for. Here is an article from Finn Stafsnes, which seems to have some hard data (fs): The content is taken from a booklet provided by norwegian battery manufacturer (Anker-Sonnak). I have done some linear interpolation between tabulated values. Therefore minor errors due to non-linear effects may be present. I can only hope that I have not done big errors in my calculations.

The voltage should be measured after the battery has been disconnected (left to rest) for at least 6 hours. A discharged battery will gradually be distroyed if stored in a low state of charge condition due to crystal growth of PbSO4, even if it don't freeze. Self discharge rate is halved for every 10 deg C (18 F) the storage temperature is reduced. Conclusion: Keep the battery well charged all the time. If you don't want to recharge during the winter, store the battery cold. And here is a mini-FAQ written by Alan Yelvington: The efficiency of batteries varies with time, temperature, and state of charge. Batteries self-discarge over time. Lead-calcium (die-hard) discharge faster that straight lead-acid. Their advantage is that they typically do not need to have the water replaced. Temperature will kill a battery over time. If a battery gets too hot, its self-discharge rate goes up. If the battery gets to cold, the reaction that produces electricity gets slowed down and the full capacity cannot be "harvested." The state of charge limits efficiency because of the reactions in the battery. If a battery is left dead for too long (this means you), the internal plates will start to accumulate lead-sulphate on them. This insulates that portion of the plate so that in can no longer contribue to the output of the battery. It takes extra power in to remove the sulphation that cannot be recouped. (EDTA will chemically remove the sulphate....) A typical battery in good condition will return 90 to 95% of the power put into it under these conditions: DO NOT recharge at a rate of more that one tenth its capacity. eg. A 220 amp-hour battery should not be recharged at more than 22 amps. The 55 excess current will generate waste heat and form lead-sulphite. The lead-sulphite is worse than the sulphate because it cannot be removed. DO NOT discharge a battery beyond 50% of its capacity. DO NOT over charge the battery. (Lead Sulphite problem again.) DO NOT discharge the battery faster than one tenth of its capacity. That is, don't draw more than 22 amps from a 220 amp-hour battery. You'll just make waste heat that cannot do work. DO use the battery and not just leave it dormant all the time. If you must have a battery for infrequent use, NiCd or gelcells are much better and are another story altogether. (ay) Another reader pointed me towards a nice solar panel charge controller the November, 1993 issue of "73" magazine. It's used by a guy with 200 WATTS of solar panels on his roof. 5.12 Online information First of all, Mosaic/Web pages about boats are sprouting up like weeds, and there's no way I can keep track of all of them. I can, however, give a pointer to a page that seems to keep track of a lot: http://www-engr.uvic.ca/ jlsmith/ This page is maintained by Jeremy Smith. Second, there's the Live-Aboard mailing list: To join, send E-mail to: majordomo@centaur.astro.utoronto.ca; the subject line is not critical but in the BODY of your e-mail write: SUBSCRIBE LIVE-ABOARD Stefan (the maintainer of the list) provided me with the following information: Previous contributions are available by anonymous ftp. Just ftp to centaur.astro.utoronto.ca, login as "anonymous" and use your e-mail address as the password. Go to the directory pub/archive. The directory pub/digests contains earlier posts filed into folders. The material in both directories is updated periodically. (The following section courtesy of sb) 56 You can FTP hourly surface analyses (one of the things you can recieve with a weather fax receiver), in the form of .GIF files from vmd.cs.uiuc.edu, in directory WX. There is also hourly raw visual and infrared satellite imagery, (from GEOS-7) which I don't know what to do with these. The files are SA*.GIF, CI*.GIF and CV*.GIF, where the * is the date and GMT hour of the picture. Then, if you are on a unix system, you can use xloadimage to display them. There are also .DOC files which describe many other sources of weather related information on the network. Also, telnet madlab.sprl.umich.edu 3000 gets you any forecast you like. If you enter the city "BOSM," you get the forecast for Boston, PLUS the marine forecast. This may work for other cities as well. You can also try telnetting to duats.gtefsd.com. This is an aviation weather service funded by the FAA. It's really meant for pilots to get weather briefings, but they don't seem to mind non-pilots using it (in fact, the particular hostname I mentioned is specifically for non-pilots; there is another host with the identical service for pilots which requires an account and allows use of some additional functions). When you get to the main menu, select "Weather Briefing", then "Local Briefing", then "Standard Briefing". Anytime it asks for a "Tail Number", just enter "N1234". The user interface is kind of clunky, and the reports are all in technojargonspeak which is probably pretty much incomprehensible if you don't know how to decode it. You will probably need a book on interpreting weather service reports to make any use of it, but for raw weather information, it probably can't be beat as a source. For example, here's the last three hours worth of reports from LaGuardia Airport: LGA SA 1850 E140 BKN 12 122/55/46/0513/989 LGA SA 1750 M110 BKN 12 122/54/46/0517/989/ 214 1070 54 LGA SA 1650 80 SCT M110 OVC 10 115/55/45/0616/987/WSHFT 28 FROPA BINOVC The 1650 (UTC) report is the longest, so I'll decode that. It says: 57 LaGuardia Airport, Normal scheduled report at 1650 UTC (i.e. 12:50 PM Eastern Daylight Time). First cloud layer is estimated to be at 8000 feet and is scattered (which I think means covering between 10% and 50% of the sky). Second cloud layer is measured at 11,000 feet and is overcast (i.e. covering more than 90% of the sky). Visibility is 10 miles. Sea-level barometric pressure is 1011.5 millibars. Temperature is 55 degrees F. Dew point is 45 F. Wind (this is the part you're interested in, right?) is from 060 at 16 kts. Altimiter setting is 29.87 inches of Hg. Windshift from 280, frontal passage, breaks in overcast. The coding is baroque and opaque, being designed for the days of 110 baud teletypes when saving every character mattered. There are also forecasts for the next 12 hours or so for selected locations, predicted winds aloft (sometimes useful for predicting surface wind shifts), locations of fronts, etc. As far as 24-48 hours in the future, I don't suspect you'll find much in the way of that, except in the most vague and general terms.

Finally, Boat/US maintains an online mailing list: "Some info will still be posted in rec.boats, but to avoid cluttering the group, we've decided to create a mailing list open to all interested boaters. To subscribe, just email your request directly to boatus@aol.com." 5.13 Should we split rec.boats? This topic arises about three times a year. The usual proposal is a split along power/sail lines. Each time the concensus, with a growing number of dissenters, is that (a) much of what is discussed here would be crossposted to rec.boats.sail and rec.boats.power if they both existed, (b) many topics, like maintenance, moorings, coast guard regs, boat shows, the grounding of the QEII, large oil spills, etc., are of (passing) interest to almost anyone who goes out on the water, (c) we all learn something 59 about the folks with whom we share the water by reading what they have to say, (d) the volume of postings is rapidly increasing and is growing too large, but a power/sail split will not necessarily address this. Recently rec.boats.racing and rec.boats.building have been formed, and they seem quite successful; I personally attribute their success to the lack of overlap in interests between the folks in those groups and "the rest of us." Analysis of the traffic on rec.boats suggests that between 1 and 10 percent of the traffic is devoted to discussions of splitting. All such discussion should take place in (or at least route followups to) news.groups. 5.14 What sextant should I buy to learn with? Good sextants are expensive (about $3000US is not unusual), and the inexpensive plastic ones (Davis make the best-known) are far cheaper. For learning, or even for real navigation, the Davis models are fine, but require more careful and frequent adjustment, and often seem to give less accurate results. They will give a result accurate to within about 2 minutes of arc, which should get your position right within about 3 miles or so. Errors made by beginners are usually computational or mistakes of understanding, and tend to be far greater than this. So a plastic sextant makes a fine tool for learning. Buy one, and if you like it, keep it as a spare when you go offshore. Hints: to keep the readings accurate, beware of temperature fluctuations, which warp the sextant (temporarily). In winter, wear gloves. In summer, watch out for having part of the sextant in sun and part in shade. And last but not least, always approach your reading from the same side (i.e., always increase the angle until the sun is on the horizon_don't increase and then decrease and then increase, etc.) This prevents backlash from screwing up your readings. (jfh) 5.15 Boat pictures, and ftp sites for boat info I (sb2) run the rec.boats FTP server(if you can use a listserv, you too can have them) for pictures. Some from my personal collection, some from the America's Cup, others from Whitbread, etc. dell1.dell.com in the anonymous FTP directory/donate/boats 60 I believe that Steve also maintains an ftp-able version of the FAQ. So do I (jfh) on the machine wilma.cs.brown.edu, in the pub directory with the name rec.boats_FAQ.Z. The file POWER.UU that's there is also of interest to some rec.boaters_it's a PC program for something to do with surface-piercing drives, submitted by Paul Kamen. It's a zipped DOS executable, and you need version 2.04 of pkunzip to unzip it. 5.16 Propellor selection GENERAL RULE OF PROP SELECTION: On a properly trimmed boat a prop of the correct pitch and diameter will permit the motor to attain it's maximum rated RPMs but NO MORE. HOW TO BUY THE CORRECT PROP: The best method of prop selection that I know of is to find a dealer that will let you try several props with the understanding that you will buy the one that performs as above. Of course it is also understood that if you ding a test prop you will buy it. Contributed by hl. 5.17 Binocular selection Contributed by (pe). The quality of binoculars shows up in several important areas. this is certainly one product area that the quality can range from junk to excellent, and you get what you pay for. The areas of prime concern are as follows: 1) Eye relief: This is the distance back from the eye piece that the image is formed. Most binoculars have a rubber eye piece that positions your eyes in the proper place. This rubber piece can then be folded out of the way for people who wear glasses. A longer eye relief is more forgiving to those who wear glasses. 2) EXIT PUPIL: Generally tied closely to eye relief, this is the diameter of the image comming out of the eye piece. The larger this is, the less sensitive it will be to having your eye is in the exact right spot. Generally speaking, larger is better. But to make it larger, the overall size of the binoculars increases. 3) Light Transmission: The percentage of light that enters the front lens 61 that makes it out the eye piece. For daylight use, this is not too critical. For nightime use, a few percent improvement in the amount of light making it through can make a hugh difference. The type of optics (glass versus plastic), the coatings on the lens elements, and the overall quality of teh lenses make the difference. Large, GLASS, coated optics give much better performance than plastic, uncoated optics. Of course, large glass elements start to get heavy. 4) Depth of Field: As a side effect of the above three items is an improved depth of field. This is the distance that an object remains in focus. The really good units don't even have a focus knob, as the depth of feild is so large that it isn't necessary. 5) GAS FILLED: The better units are sealed, and purged with dry nitrogen. This keeps moisture out, keeps the lenses from fogging, and helps improve the overall optical qualities. 6) THE CASE: A rubber armored, rugged case will help prevent damage. Lens caps that stay with the unit keep them from getting lost, and make it much more likely that you will put them back on to protect the lenses. You may want to check out the West Marine catalog. They have a chart listing all the important characteristics of the binoculars that they sell. Compare it against the specs of a unit you are considering. Decide if you might ever need to read the number on a channel marker at night. My advice is to go with the best that you can afford. Properly treated, they will last forever and you will not be sorry. 5.18 Blue book value of boats Contributed by jjensen@kaiwan.com (John Jensen).

One answer is to do it directly: NMEA data out -> RS232 data in, and NMEA data return -> RS232 ground. The signal is 4800 baud, no-parity, 1 stop bit. But here's a better answer, courtesy of Bob Curtis (bc@gate.net): Here's a simple circuit to keep your instruments safe: a ----/"/"/"/"----+ +---+------/"/"/"/"------ +12v 5k _ _ _ 5k --- _/ +-------------------- to RS-232 rcv. / " _ --- _" _ _ b ----------------+ +------------------------ to RS-232 common _ _ <- might not need this connection gnd ------------------------+ You will have 100% isolation if you leave off the ground connection shown (recommended). Some systems may work more reliably with a common ground. The parts (2-5k resistors and a photo-optical isolator) will cost about $4 at any Radio Shack. 6 Bibliography 6.1 Magazines AMERICAN SAILOR, none, This one is for members of USYRU. Almost exclusively for racing. Dave Perry has a short but interesting "rules corner". ASH BREEZE, none, P. O. Box 350, Mystic, CT 06355, $15/year (4 issues). The journal of the Traditional Small Craft Association. Member-contributed articles about design, construction, and history of 63 traditional boats. Members also receive discounts on books published by International Marine.(al). BOAT DESIGN QUARTERLY, none, P.O. Box 98, Brooklin, ME, $24/year (only 4 issues). Each issue contains six to eight reviews of boat designs. This magazine is mostly the effort of Mike O'Brien (who also writes for WoodenBoat magazine).

Includes instant boat construction, origami steel boats, etc.(mp) Possible new address (subscription dept?): Boatbuilder, 76 Holly Hill Lane, Greenwich, CT 06836-2626. COASTAL CRUISING, none, The Magazine of Achievable Dreams. This rag was formerly called "Carolina Cruising" and probably still should be. Concentrates on the ICW around and about its Beufort, NC home base. A harbor profile in each issue with a color arial photograch as a centerspread. Quirky columns written by people who are really into bringing the spoken accent to the written page. Printed on cheap newsprint paper and comes out 6 times a year. Unless you live or cruise in the Carolinas, save your money. (wms). CRUISING WORLD, none, Good articles, wonderful reader service called "Another Opinion", which will tell you about other readers who own the same boat that you do (or that you are thinking of buying), and who might be interested in telling you about it, Extensive brokerage and charter listing. -jfh-. GPS WORLD MAGAZINE, none, Monthly magazine covering the spectrum of GPS usage. Current regular subscription rates: US $59, Canada $79, Foreign $117. Advanstar Communications, P.O.

Has suspended publication as of January 1993. (tl). JOURNAL OF NAVIGATION, none, The main problem is this is a quarterly publication (at best), that often suffers long delays in delivery. It has an interesting mixture of high end and low end stuff. For instance it will have discussions of what the piloting station of a large freighter will have the next decade alongside a report of a last (ill fated) Atlantic voyage of a junk rigged 30' cruiser. (rb). 64 LATITUDE 38, none, The SF Bay sailing rag. Cheap paper, irreverant staff. Far more honest than any other sailing rag. Latitude 38,P.O. Box 1678,Sausalito CA 94966,USA.

MESSING ABOUT IN BOATS, none, This small magazine with its own strong identity and readership may interest those who enjoyed Small Boat Journal before its change. Costs 20 buck per year. 29 Burley St., Wenham, MA 01984. "This is a great little magazine filled with reader-contributed articles and good classifieds (especially for readers in New England). Very entertaining, and you can't beat the price." (al), "particularly since it comes out every two weeks. The primary focus is on boats for the "little guy," rowboats, patched-up boats, and homebuilt boats. There is a lot of coverage of off-beat boats, and most issues include a design by Phil Bolger." (wv). MULTIHULLS, none, 421 Hancock St., N. Quincy, MA 02171, (800) 333-6858, $21/year (6 issues). As the name states, this magazine deals exclusively with multihulls. Coverage is divided about evenly between cruising, design, building, and racing. They also sell books, videos, and posters.(al). NATIONAL FISHERMAN, none, The working seaman's magazine. Printed on newsprint, filled with editorials about why the fisherman cannot make it in the modern USA, and articles about how well EPIRBs *really* work, etc. A *great* mag. Wonderful classifieds. OCEAN NAVIGATOR, none, Informative article; passagemaking information, info on nav hardware and tools. The letters are worth the price of admission. Nav problems at the end of each issue that include piloting and offshore celestial problems, with answers. Only magainze that I read cover to cover. Some articles about electrics tend to be slightly screwy-Nigel Calder can't distinguish amps from amp-hours. OFFSHORE, none, 220-9 Resevoir Ave, Needham, MA 02194. Covers the Northeast coast from New Jersey to Maine. Good coverage of the area with plenty of local interest stories, marina profiles, safe boating, navigation and area history. Slightly skewed toward powerboats but plenty of interest to sailboaters, too. Regular columns on local boating news and Coast Guard Search and Rescue summary. Series by Dave Gerr on understanding Yacht Design contains many of the articles on which his book "The Nature of Boats" is based. Excellent classified section with a 65 unique "renewable guarantee" that will keep your ad in until sold for a one time fee of $25.00 (wms). POWERBOAT REPORTS, none. PRACTICAL BOAT OWNER, none, published in Poole, Dorset, England. Practical Boat Owner Subscription, Quadrant Subscription Services, Perrymount Road, Hayward Heath, W. Sussex, RH16 3DH, United Kingdom. Another reader notes that "The current Practical Boat Owner gives the following address for overseas subscriptions: Practical Boat Owner, PO Box 272, Haywards Heath, W Sussex, RH16 3FS, UK. Tel: 0444 44555." P.B.O. is great for boat tests (yachts any size, motor boats mostly small) and simply excellent for how-to-do-its. Editorials reflect the British scene since it's a British magazine. The editor, George Taylor, answers queries in person by return of post. PRACTICAL SAILOR, none, These folks test out products and do sailboat reviews and compare products made by different people. They also answer questions. They have no adverts, so that their information is nominally unbiased. <As I learn more and more, I respect them less and less. They often test products in ways that aren't all that reasonable. Their test of rope, for example, was based solely on abrasion resistance. Fine for your mooring pennant, but not the whole story. Their test of other products has not impressed me either. And, last but not least, they have wacky ideas about galvanic corrosion_I would not trust anything these guys said about electricity. It helps to be an educated reader. (jfh) Practical Sailor's Subscription Dept can be reached at 1-800-829-9087 or PO Box 420235 Palm Coast, FL 32142-0235. Subscriptions are $72 annually, although I think I've seen discount offer's in Cruising World.

Good charter listings. Good brokerage listing. SAILING, none, Published in Port Washington, Wisconsin. It's large format (11 x 14) can have some pretty striking pictures. They're a general interest sailing magazine. Their design editor is Robert Perry. There's a "boat focus" column on one particular boat each month written by an owner... usually nice family cruisers. SAILING WORLD, none, Mostly about sailboat racing. Very good on that topic. SEAHORSE, none, The magazine published by the Royal Ocean Racing Club in England. Far and away the best coverage of big-boat racing, and 66 not afraid to get technical.(pk). SMALL BOAT JOURNAL, none, now "Boat Journal." <Never look at a copy of this printed after 1990, especially if you are a sailor. Early issues are real treasures_circa 1978-1980, they were the best, most honest, best produced, small sailing mag around. SOUNDINGS, none, Good articles on all aspects of boats; great classified section. $18.95 FOR 12 MONTHS. 35 PRATT STREET/ ESSEX,CT 06426. 203 767-3200; 203 767-1048 FAX.

Address is: SSCA// 521 S. Andrews Ave.// Ste. 10// Fort Lauderdale, FL 33301 USA. WEST MARINE'S ANNUAL CATALOG, none, For pure information per dollar, this has got to be the best buy around. True, it's a once-a-year journal, but their West Advisor sections on how to best run marine plumbing, what kind of wire is best, etc., is really worth reading. Slightly biased towards promoting the purchase of expensive items, though. WOODEN BOAT, none, Lovely pictures, informative articles, and they pay attention to *new* woodworking as well as old. They have a love affair with Maynard Bray and Phil Bolger, though, and you have to watch out for this bias -jfh-. YACHTING, none, The very rich person's boat magazine. Most boats over 60 feet. YACHTING QUARTERLY, none, A "video format" magazine; about $100 per year for four videotapes. These tapes include a fair number of how-to segments, and are supposed to get you an idea of how-they-hoist-the-chute-on-the-winning-J40, and such things. 6.2 Nonfiction about sailing trips SHRIMPY AND SHRIMPY SAILS AGAIN, Shane Acton, This is an 67 amazing story of a guy who spent eight years sailing the world in a caprice class 18ft boat. None of the other books I have read on the subject come close to this achievment. A none sailor, his own money, very very limited funds. This guy is my hero. MAIDEN VOYAGE, Tania Aebi, 1988 Excellent. An 18-year-old girl/woman circumnavigating westward in a Contessa 26. 117 DAYS ADRIFT, Bailey. SECOND CHANCE: VOYAGE TO PATAGONIA, Baileys, Interesting contrast with Slocum's earlier account. FIRST YOU HAVE TO ROW A LITTLE BOAT: REFLECTIONS ON LIFE AND LIVING., Richard Bode, It is a zen-like outlook on how sailing and life are so similar. Friends who have read it say no skipper should be without it - it's really good.(bt). GYPSY MOTH CIRCLES THE WORLD, Sir Francis Chichester, 1968 Another classic, of a solo cicumnavigation in a fast but vicious boat, best read together with The Lonely Sea and the Sky. THE LONELY SEA AND THE SKY, Sir Francis Chichester, 1964 Excellent auto-biography of the great adventurer. Includes transatlantic voyages, and his pioneering first flight (NOT non-stop!) across the Tasman Sea. TWO YEARS BEFORE THE MAST, Richard Henry Dana, Harvard boy goes to sea, and writes eloquently about the details of sea life.
