I can see how Reto’s yard is almost vertical. Thank you for that piece of advice. Also, I saw on your website your kits allow for the keel shape of a proa without strip planking. Brilliant! I didn’t think that was possible. Which is why my wa’apa has a flat bottom.
I reckon,,,,but what would i know,,,that on the centerline of the sail,from the tack to the middle of the leech,,that should be somewhat of a naca foil shape,,,the spars also need some shape somewhat resembling the same shape maybe...that means you would have a somewhat radial design sail,,,the micronesians wove quite a fullness into their sails from the tack to about 40ish percent up the centerline of the sail...they also cut large cutouts in the leech...encourages the vortex,i hear...cool boat..nice vids,,,,i think theres a lot of power to be gained with sailshaping,,,
Hello, I made my sail from a cheap pvc foil from the hardware store. So it doesn't have a profiel. The front spar is a surf mast therefore straight. I glued the lower spar with curves but cut out the sail to match. A sail profiel is therefore only created by the fact that the spars bend a bit and the foil is somewhat stretchy. I have my own explanation of the cutout in the leech. Practically every proa builder I know realizes that his boat wants to go into the wind at the beginning. So the sail pressure point also has to move forward. The easiest way to do this is to cut something out of the trailing edge. Until it fits. I could imagine that it was the same with the Polynesians and then gradually became the norm. And if you don't use sail battens, the cutout is also good.
I still don't understand what the advantage of "proa" is. The entire time the assistant is out of the water and listing as if it were a monohull. I still don't understand the proposal.
Hi, that's a good point. What are the advantages of a Proa? First of all, I find interesting to try out something different. The wind always comes from the same side, you can steer without a rudder, you have a crab claw sail. Why is the outrigger to windward? At catamarans or tries, the mast is in the middle. The hulls not only have to carry the weight of the boat, but also the sail pressure, which pushes the leeward hull into the water. What increases the resistance. The Proa only needs to support its weight. The sail pressure lifts the outrigger which moves then through the 800 x thinner air. And of course, every proasegler wants to have the outrigger flying. It is also much easier to right a Proa after capsizing, because it usually only capsizes up to 90°. I think that Proas still have quite a lot of potential. So if someone would put a lot of money and time into it, he could still achieve something. But I have just time to invest. There are more aspects, but that's going too far for now. I think I'll make a video about it. It's just fun for me. Even if an old Hobie 16 is still faster than my Proa.
@@fjordproa6510 I see a lot of people involved with Proa, they must have their reasons. Anyway, thank you very much for your attention. I'll follow you and learn about the subject. Good luck and stay with God!

Pretty cool tho

nice video! there are things you just can't see from a camera mounted on the boat!
Yes that's true.
A chaseboat is always good to have.
