Dinghy Sailor Wants to Go Cruising

Hi Steve- I read a question in the Q&A section of cruising central. It was the one where you said that getting into sailing dinghies for a summer would be comparable to sailing a larger boat for a few years. I already know how to sail and I sailed a dinghy as a youngster. Now I’d like to get into cruising 30-40 footers long distances. Would dinghy racing also benefit me as far as learning and experience in sailing? There are many dinghy fleets here in San Diego that I could readily join. I’m a 50-year-old guy and I’d like to become a capable cruiser before I’m too old. Thank you very very much for your valued guidance. Kevin

Rudder Stock on an Aluminum Boat

I am building an Aluminum Sailboat with a spade rudder and rudder stock. I am planning to use UHMWPE plain bearings. Would it be a good idea to hard anodise the shaft in the area of the bearings to reduce the wear? Would there be any corrosion issues? Thanks, Howard

Sailing Short Handed in Heavy Weather

I received Surviving the Storm for Christmas, and have found it to be a very informative and useful book. It is great that you provide specific advice on what to do in different situations. You also inspire a great deal of confidence in the boat – that most modern boats will survive if the crew is careful.

I do have a couple of questions. How do you maintain active tactics like running off or heading up into large waves when 1) you are shorthanded with a husband and wife only on board and/or 2) it is night and you can’t see the waves coming? Regards, Hank

Smallest Boat for Cruising

I noticed that your boats keep getting bigger and bigger. What do you consider the best minimum size for cruising? My dream is to sail down the coast of California to Mexico, Panama Canal, Caribbean, and then Greece, Italy, France, and England. Thanks for writing what looks like a wonderful book. Sincerely yours, Sal

Birdsall 60 Range of Stability Calculations

Hi ya: For years we have lusted after your boats (Wiroa was one) but couldn’t afford them. Our own boat Gungha (Alan Buchanan design in steel, round slack bilge’s and overhangs) was getting too small. We owned her and lived on board for 21 years.

Last year we were lucky to change boats and boat designs. The new boat is a Birdsall 60. She really is the boat of our dreams. Heaps of space, stable and fast-as. I can’t think of anything about the layout or performance of the boat that I could criticize. We have just made our first offshore passage from NZ to Tonga with heavy weather and she went like the clappers. So no problem there. There is however a problem of lingering doubt vis-à-vis the design.

I have been used to the deep draft and 45% ballast ratio of Gungha (nice and rolly). I always knew that if she was capsized she’d snap back upright in moments. I know you’re probably familiar with the Birdsall designs, as they resemble your own in some aspects. This yacht is 63′ on deck, 60′ at the waterline. She has a 14’10” beam which is carried aft but certainly not forward (very narrow there) and she has a 6′ draft.

The yacht is single chine steel with a long (about 17′ fore and aft) fin keel and a skeg-supported spade rudder. The hull of the yacht draws a little over 2′ with the keel making up the rest of the draft. The yacht is double-bottomed fully with welded in tanks, which hold a total of 800 gallons of fluids. The deck plate and all construction techniques have concentrated all the weight as low as possible. The yacht has a center cockpit and trunk cabin with considerable buoyancy.

My problem is this. The yacht is adequately stiff even in hard conditions but…she only has 4 tons of ballast. Her total shipyard weight is 27 tons. What do you think of that and her ability to be tipped over????? We have sailed over 60,000 miles and prior to that I was a commercial fisherman in Alaska…Am I getting paranoid in my old age?

Thanks and cheers, Mike

Tri-Radial vs. Crosscut MainSail

I have a 1987 Ericson 34 MKII and am looking to replace my mainsail. Why would I consider a tri-radial verses a cross cut mainsail? I do not race but the family enjoys going fast. Thanks

Anchor Shackles

Hello, Thanks for your excellent books and CDs. We have purchased your Encyclopedia and CD but have not gotten off cruising to the Carribe yet. Soon though.

In following your recommendations on anchoring, (we purchased a 65 lb Spade Anchor and will back it up with 200 feet of ACCO 3/8s Chain with oversized links on each – and following your admonition it must be the right size as our dockmates have laughed at the size we bought), but we had a question as to what shackle you are using with your system. We want to insure that our shackle will not be the weakest part of our system. Can you advise the maker and size of shackles in use on your boat? Ed & Sue

Electric vs. Hydraulic Motors for Windlasses

Hydraulic motors. You mention the problems with running your anchor windlass, the need for large wire size to minimize voltage drop on the long run to the bow. Why not power the windlass with a hydraulic motor? You already have a pump onboard for the auto pilot, even adding an additional pump would provide some redundancy for the autopilot system. Now all you need is a tiny motor and a couple skinny (1/4 in od) lines running up to the bow. These motors are robust, simple, easily speed and overload controlled, corrosion resistant (I own a chemical plant, believe me I know about corrosion!), very lightweight… I first saw these used at a plant in Norway. All the agitators drive motors (probably 10 total) were run by a single hydraulic drive pump. Speaking of multiple motors, how about that big power winch you use on Beowulf? Slap a hydraulic motor on that thing too and get rid of the need for a 24 volt electric system all together!

Steps for Getting Ready to Head Offshore

Before each passage we’ve learned that it pays big dividends to go over all of the boat’s systems, rigging, and sails to make sure everything is in the proper condition. In the past couple of weeks we’ve spent a few days on Beowulf, getting her ready to head offshore. Here are the items aboard we’ve checked:

Full Battened Mainsails

From time to time we read in the yachting press about problems with fully battened sails on long down wind passages. We’ve been using these sails for almost two decades now, and have found that with the right approach they are less of a problem than conventional sails.

There are two key ingredients: first, you must have a good vang to keep the sail from twisting off and putting excessive load on the spreaders. If your boom vang to the mast isn’t strong enough, rig a vang to the rail on those long tradewind trips.

Second, chafing gear must be done correctly. We’ve found that thin UHMW plastic (usually 1/32″ thick) can be sewn onto the sail in all vulnerable points (at the spreaders and where each batten crosses a shroud – both need to be done for full hoist and reefed positions). The UHMW lasts for years and does not allow the sail to chafe.
