The hull was purchased from www.classicsailboatmodels.com
The winch from http://www.servocity.com/html/servo_...gearboxes.html
Sails from www.carrsails.com
Aluminum mast from www.ludwigrcyachts.com
Wooden booms from www.pondboats.com
Brass fittings from www.modelyachtfittings.com

Ballast totals 63.7 lbs, in three separate pieces, all of which will be removable.

This boat is for recreational use only. I am trying to replicate the majesty of the "J"s, therefore, the mast is precisely scale length. Though the real ones did not use a jib boom, mine will be attached sort of close to the bow at 8.9% of LOA, unlike some model racing "Js" at around 13%. The sail plan is individual, and mine will carry a full measure, which will limit it to light air.

Of the 10 America's Cup racing Js, I chose the 1934 Endeavour because of its quintessential lines. Simply gorgeous.

I'm happy to answer any more questions.

ooby,

The J boat is looking good, it's to heavy for me to move around. I think I will build a 36" version of the J boat when I finish the EC-12.

Check out this web site of the 36" J boat.

Plans? Getting started?

RC-Archer,

To the best of my knowledge, there are no kits or semi-kits of an AMYA "J".
www.deltamyc.com/boat%20building.htm will take you through the process of building a Shamrock V, which later won the J-Class NCR. Its LOA is 89.75 in vs Endeavour's LOA of 97.375. Since these boats are 1:16 scale, you'll see these types of differences through out the ten "J"s.

The first step is to decide which J to model. The next decision will be to scratch build from line drawings, or purchase a glass hull.

Line Drawings of individual hulls and decks in 1:16 scale are available from Rene Serrao, 650 Ketch Harbour Rd., Portuguese Cove, N.S. B3V1K1 Canada

In answer to your question above, if you decide to go the glass hull route, my advice is to call the prospective seller and get comfortable with the info provided. In my case, Bob Sennott was absolutely great to work with and provided hand written illustrations of critical areas and measurements. These boats are scratch built and highly individual. "How" you build one is essentially up to you.

John Hanks, current AMYA J-Class Secretary wrote a series of 5 build articles, beginning with the Spring, 2000 AMYA quarterly. I recommend obtaining past issues, volumes 119, 121, 122, 123, 124. He also wrote an article on building a planked deck in volume 149.

I hope this helps. I'll do my best to answer any further questions.

RC-Archer and Casy,

Since you both want "J"s in your living rooms, how about adding this book to your coffee table, Enterprise to Endeavour, The J-Class Yachts, by Ian Dear.

ISBN 0-7136-5176-8 (UK)
ISBN 1-57409-091-7 (USA)

Ed, like you, I've thought of a smaller J to pack around...get in more sailing. Don't know much about the Yankee III, but will keep my eyes open.

I'm considering: http://canterbury-j-class.org.nz/home.html

ooby,

Thanks for sharing the information on the Canterbury J boat. I emailed Simon and asked how much the J boat will weigh when fully rigged, it comes in at just over 14 lbs. At 48 inches and 14 lbs it is easy to transport and carry. I emailed him back to find out the cost to ship it to U.S from N.Z.
