I saw this on that other proa forum ; )

This is an absolutely wonderful document espousing constant camber construction for working multihulls by multihull pioneer and all around smart dude, Jim Brown.

Oh, and there are proas.

Thanks for posting this Luomanen,
i totally agree with Jim’s vision on growing population and resources, just like in the “park it dad” piece on wingo.com
guess that vision is what got me into proa’s, only the essentials (and crazy speed)
although i might be screaming for a motorized skiff if i were a worn out coastal fisher.

Thanks Luomanen!

This is a great article. I have not read all of it yet.
I really like his constant chamber. It sort of reminds me of Fredrik Ljungströms Arc bow hulls, but with more possible hull shapes and cold moulding instead of strip planking.

Cheers,
Johannes
