Bamboo-- narrow, but long.
The idea of more buoyancy forward is what I was wondering about in my BOSS thread. I'm guessing that you have a traditional rig with the aka/ama set in the center of the boat, yes?
There really is no logical reason for this other than height, but that thought came to me while out on the boat watching the ama bounce along the surface.
Actually, without the forward buoyancy, the tri can "trip" over the ama when it's going fast and it hits a wave. Catamarans have had very similar problems-- the Hobie 16 is notorious for it's propensity for pitch-poling.
I wonder if increasing the angle of the BOSS ama; pointing the nose up more, would be helpful? Seems to me that it would respond similar to the Filipino ama but less efficient when the nose is driven down.
Maybe, but the bangkas have two akas. The BOSS rig has only one. When you add the different hullforms of the amas, I think we're dealing with apples and oranges.
Too bad the summer is coming to an end Chris. It would have been nice to meet up somewhere between the two of us to do some sailing together.
