calculations to find out how these proa concepts really differ. Proa concepts dealt here are as follows: • Pacific proa, original concept with light and short windward hull, accommodation and mast at large leeward hull. • Atlantic proa, accommodation and mast at windward hull, smaller but as long leeward hull

Nov 27, 2020 · The Pacific Proa has the ama on the windward side, and the Atlantic Proa has the ama on the leeward side. I have wondered if anybody has built a "Tacking Proa", where the ama is on the leeward side on one tack, and the windward side …

Sep 2, 2020 · The long and short is: the Everglades Challenge has been on my "bucket list" a few years now and I'm aiming to finish in 2022 or 23. Im about 6 months into the planning and designing a raidboat pacific proa to build in my garage. Im looking for comments and suggestions, and answers to a few specific questions.

Jun 22, 2010 · Atlantic Proa - Smaller, but heavier windward hull holding most (or all) accommodations. Larger, but lighter leeward hull. Larger, but lighter leeward hull. Weight seems to be around 60% in the windward hulls versus 40% in the leeward hull.

Sep 13, 2008 · Why proa? Ok here is my thinking; 1*Out of the three multihulls it is the quickest easiest build, A tri is a hull plus a simple catamaran, A catamaran is two hulls, a proa is one hull and a float, I would estimate about 75% the work of building a …

May 2, 2015 · Looking at Tehro Halme's Ping Pong proa, his next boat was the EQL-7 proa (7 meters = 22ft or so), you notice that on his second boat he has gone from a flat bottom to a vee shaped bottom, deadrise angle 45 degrees at a guess. Maybe email Tehro and ask him why he went from a flat bottom in this first boat to a vee bottom in his second boat.

Oct 30, 2011 · Again, yes, it is somewhat counter intuitive that the ama remains to windward at all times, at least with a Pacific Proa. Pacific Proas are the traditional version of this design, originating from Polynesia. There is actually another kind of proa, a modern variant called the Atlantic Proa. The AP keeps the ama to leeward.

Oct 24, 2012 · I understand that a true proa is not able to tack because of the statics of the rigging, so, for the correctness of the terminology, we make the thought experiment proa vs outrigger. We keep all the parameters of the two boats identical, just the rigging differs in the way that the outrigger can tack and the proa can shunt.

Apr 20, 2018 · I did a lot of research of hull shapes. A square has the least waterline per cu ft. (when the beam is constrained), while ovals have better hydrodynamics. A pacific proa has the wind from one side only of course. An asymetrical hull has some advantages in proas. The deep micronesian proa hulls have a lot of wetted surface but don't use ...
