Thanks Colin

liked the Zen of proas part ---agree

The only one I,ve seen locally is SLINGSHOT
the only pic found was one on this site to scoll down to

A proa design speed trials attempt in the 70s by the Gougeon Brothers ,-West System Epoxy guys,-here in MI .
The current attempt at the speed sailing record is also in a proa ,--much more refined .

Recall an earlier post with Grob in your area ,
he has been working on an interesting 4 hulled fold up sailing craft which initially had a two boardsail type sailplan for it ,-suggested the A frame type rig used on the 12 ft Catyak --{no longer made} ,-but was a good simple rig like the proas .
Will be interesting to see how that progresses .
The basic platform was fasinating and has all types of interesting potential applications ,-paddle boat -fishing platform ,etc brilliantly designed to fold up and fit on the cartop.

thanks again
Carl
