I built my first Proa 5 years ago for testing. I was very pleasantly surprised.  
The main hull I later used as the ama on my  Great Proa.

              Actually, my big boat is a converted PORT MADISON PROA.  There is no blueprint, only the entry in the Duckworks Magazine Design Contest #6.  
The construction is Stitch and glue with 6mm ply for all but the bottom which is   10mm. The rudders are  outside, connected with wire ropes, and are easy to  pull up. You can reach everything from the cockpit. The cockpit itself is 1m by 2m and can be removed to make transport easier  
  
LOA - 7.5 m  
BOA - 4.5 m  
  
The  sail is a crabclaw, that runs on a rail. 
In the spring I will send you detailed photos and drawings, if everything goes well.

              There are several reasons I chose to build a Proa.  
              Originally, I wanted   to build a TIKI 26, even going so far as to buy a set of plans - without thinking where I would build   it or how to transport the hulls,  etc. Being a solo   sailor was important to me, but this boat was a little bit too much - too big and too complicated.

                  Now it is getting well along | 
                 
               
              One day I saw a movie on TV about the TAUMAKU project. It has fascinated me. Some  natives    built a Proa without any metal parts, such as nails, screws, etc.  I thought I could sail such a boat alone.

              I looked everywhere,   in books, magazines and the Internet for information about this type of boat,   and thus I found  the Port Madison Proa at Duckworks Magazine. In my eyes, this boat, in all ways, was the best of the bunch.

               I had built the small   Proa in Stitch and glue construction  to test the behavior of this type of   boat in all situations. 
              In doldrums as well as  storm, it behaved wonderfuly and   safely.

               In spite of some resistance from my wife, I then decided to   build the larger boat.  
              I sat down and made a drawing 1/10 scale. I used the  Tiki 26 construction drawings and the information on the  Madison Proa to design my own boat. Due to the length of the   three 6mm plywood sheets,  I decided on a total length for the boat of 7.5 m.   I used the TIKI's beams only bent, it was great work.   For the AMA, I used the main hull of the small Proa. (I had two boats at once)

               I deliberately moved the outside of the hull/ rudder attachement to avoid  major damage and plan to keep the crabclaw rig because any boat sailing without one, in my opinion, does not   deserve the name PROA.

               The first sail will take place on a small lake in the Salzkammergut and if   everything works, I will sail farther.  (My dream is circumnavigating Europe)  
                A report with photos follows, as promised, in spring. Until then much needs to be done.
