I really like the general concept of those boats, good looks, versatiliy and simplicity of the rig, straightforward building process out of common materials.. I would build one out of plywood, scantlings call for 12mm plywood side panels and single 19mm bottom panel.
The New Haven sharpie is maybe too extreme in proportions, the North Carolina 33 model looks like it could be more suited for my use being stiffer and could stand better to its sail area having more beam and fuller ends.
Mr Parker also recommended building weighted centreboard (up to 1000lbs) filled with lead shot, sand and polyester resin. The rest of the ballast (if needed) could be under bridge deck or as a one inch steel sheet ballast shoe on the bottom.
I have zero expirience with the type and boat design in general so please correct me if I am on the wrong track thinking that such boat would be fun, fast daysailer, beach cruiser-pushed to occasional odd week cruise for two in the Adriatic sea which is different than Long Island sound and Pamlico bay.
The boat I have now is just too slow and if I may use this expression, un-inspiring to sail so i paddle kayak and stand up paddleboard most of the time.
I also like multis, odd speed machines especially. I am currently building Gary Dierking's Va'a Motu outrigger sailing canoe and surfski kayak.
My ideal "big" boat would be clc's Madness proa, I have purchased the study plans for that one and I have to say it is one large project filled with hundreds of fiddly bits
Thank you for your help, Igor
*I was wrong about the Egret that rolled downwind, it was not the Parker's version of the boat but mr. Simon Lew's fiberglass one from some short production run with twin bilge boards instead of centreboard. The conditions in the Atlantic once he got out of the inlet remind me very much of local conditions in the Adriatic.
