Hi all,

that same site also has this Ferrari of a flying proa. What a sleek craft ! I quote:

"The main hull is assymmetrical with the flat side to leeward and the curved
side towards the outrigger to windward. It is very narrow and deep. The
outrigger beams are lashed to the main hull at an angle, so that the upper
part of the hull tilts away from the outrigger. The hull develops
hydrodynamic lift to windward, which counters leeway. Because of the
built-in list, particularly when flying the outrigger, a vertical component
of lift is developed, reducing effective displacement and wetted surface,
and hence reducing drag.
The outrigger beams are not directly connected to the outrigger. Four long
narrow pieces of timber act as an ingenious spring system, allowing the
outrigger float to move independently from the main hull up and down waves.
This advanced engineering of the connection of outrigger to the main hull
may be thousands of years old."
