In case anyone is scratching their head on the sail dimensions on sheet 2, they appear to be drawn at a 3/16" scale with the cad scale set to 3/8". I believe doubling the dimensions shown will give the proper size of the sails.

 I like how the bilge board cases are worked out. One of the more time consuming jobs is properly fitting a CB/DB case and I didn't look forward to building and fitting two of those beasts...
