I’m aware another member of this forum is also building a Bristol Pilot Cutter “Katie”, so I hope members don’t mind if I share my progress with the same model. The drawings that come with the hull moulding show some information but leave plenty for the builder to work out for themselves. I did buy the reprint (1999) of "The Sailing Pilots of the Bristol Channel" written by Peter Stuckey and first published in 1977. There are also lots of photos on the internet, which can help. The aim is to a make model that sails but also looks reasonably accurate. To help judge the scale, which is 1/12 th, I bought a dolls house figure to the same scale.
I added a length of 7/16th brass sq. section to the keel. Adds strength, weight low down and also increases the lateral resistance. The final ballast will be lead shot, testing in the bath. The plan is to use two winches, one for the main and the other for the jibs. In this way these can be sheeted in as on a full size boat, moving across as the boat tacks, although I don’t expect great windward performance.
There is a blog
