If you google
the word "GAIASDREAM" go to images
, see a PROA, the origins of which i think are south pacific
indiginous. This particular proa was built by a Dutchman in northern NSW Oz. Doubt its for sale
Perhaps this guys website may inspire you to expend your concept
horizons a bit.
The pacific islanders have used proas since the year dot.
On "giasdream" the foot of the mast
moves fore and aft on a track allowing 'rake adjustment' so great as to allow the boat to sail backwards (IF you REFUSED to turn around that is !).
As i recall
this ship, as the Dutch call boats, has sailed the Pacific extensively.
Maybe, I you like the proa concept
, you could find some for sale
Just a thought but really, giasdream, as a sailing vessel should interest ANY yachtsperson Id think.
