Modern looking outrigger. The crab claw lateen sail has attracted interest amongst German engineers and aerodynamicists. For it’s size it turns out to be super efficient due to the turbulence it creates.
I was told they were the fastest sailing boats - in the world - that were built for everyday use ie fishing.
And 'going-about' was an awesome affair, as the skipper had to walk down a half-decked surface ( the other half being access to the hull for storage ) with the mast and sail to poke it into a recess at the other end. Took real balance and strength. This was not a regular event as the Trade winds were consistent in direction, speeds and timing - so taken into consideration when planning a trip.
