a proa is a polynesian style outrigger boat. with ONE outrigger
that is smaller.
it is assymetric. the smaller outrigger always faces the same
direction as the boat 'shunts' instead of tacks the wind.
(shunting is like going goofey foot on a snow board instead of
carving 180 when you turn)
the main body hull possesses 2 wing sails , rigged at extreme
ends of the hull. they are used for sailing, until they are
needed for flying.
when they are needed for flying they are let down horizontal
and the outrigger mounted aero-propeller then throttles ( it
can throttle while the wind sails up vertical used for sailing to
supplement the boats power, like in motor sailing using the
hydro-prop to supplement the boats wind driven sail inertia)

So fast you think they might take off. [minoradjustments, Jan 08 2026]

Yo, teslaberry, in 2014 sailboats didn't foil at over 65mlph. But now a takeoff from water is eminently possible if the translation to flight can be handled gracefully. |

Also, battery tech is so good now that intermittent flight — like a flying fish, in spurts — is possible without the necessity of a heavy engine needing fuel. The battery could be charged by the boat's motion and discharged periodically when "flight" is possible. (Cranks are being removed from racing trimarans in favor of all-electric assist.) |

Though not about a proa, the link will give you some idea of what is possible. A proa would be lighter and less complicated. |
