Cruising proa concepts - Boat Design 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
Proa design | Boat Design Net 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 tri 2*I only live in one hull The same as a tri
Raidboat Pacific Proa - Boat Design Net 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
Tacking Proa (for lack of a better term) | Boat Design Net 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 on the other tack Tacking rather than shunting
Proa Questions: Atlantic vs Pacific | Boat Design Net 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
CRUISING PROA CONCEPTS II - Boat Design For every type of proa, the structure mass (ama + vaka + aka) is 1000 kg Using above, the pacific proa has length of ama 8 0 m (approx 70 % of vaka) and vaka 11 2 m Atlantic proa has similar lengths, but accommodation hull weight double the structure hull See the table on next page The crew and equipment are 200 kg and are placed on the ama
21 proa design New Zealand | Boat Design Net 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
proa | Boat Design Net Hi proa people, Was just havin some beers with a fellow sailor and he told me about a Russian proa that he encountered somewhere on the coast of Thread by: Daniel Reilly , Mar 29, 2025 , 4 replies, in forum: Multihulls
Proa Circumnavigation? | Page 2 | Boat Design Net Proa rigs with headsails or spinnakers need the old one removed furled and the new one hoisted unfurled, but on rigs without headsails (Harryproas), it is a simple, safe and low stress operation Tacking boats need to have enough sail up to power the boat into and through the wind and waves (or, more commonly these days, they start the motor)
Raidboat Pacific Proa | Page 2 | Boat Design Net Current proa Trivial Obsession has end mounted rudders and a cambered panel junk style staysail There's no fire in my belly to take another run at the EC at 77 but I do miss doing the Texas 200 If the rig and rudders on T O trial out ok I'll build a replacement for P52 probably foam and glass, definitely a schooner rig
