Here is an Atlantic Proa that Newick designed in 1982 after the 1980 Ostar where several proas failed to finish. He wanted to design a proa that could be a good performer in short handed events and was accessable to the common man. The proa was 44 x 23 foot, displaced 4000 lbs and carried a total of 650 to 790 square foot of sail on it’s 2 wing mast schooner rig. This design followed on from Newicks 1979 design for Nick Clifton’s Azulao 11 Atlantic Proa which is 42 x 20 foot weighed 3000 lbs and carried 630 square foot of sail in a schooner rig. Notice the 44 footer has more beam, is heavier in displacement and carries more sail area. Also notice the slightly fuller hull shape in cross section and in the ends on the 44 footer compared to Azulao 11. This may have been to get better speed in a seaway due to less pitching.
The later 44 foot proa design was built using constant camber hull shapes of 4 plies of 2.5 mm WRC or spruce covered with 330 gsm cloth and epoxy resin. There is a keel, gunnel and single stringer at the waterline of each hull (which are identical in shape). The accommodation pod is constructed of 6 mm ply on the outside 12 mm vertacell and 3 mm ply on the inside. The crossarms and masts are timber covered with glass. As you can see at least there is 2 “berths” in this boat and some storage. Not luxury but functional. I know a smaller version (32 foot) was built and raced lasting quite a few years. I cannot find any reference to the 44 foot being built or raced. I am still trying to find the study print I have of Newicks 60 foot Atlantic Proa intended to be a cruiser racer. It has some real accommodation and would have been fast.
