I thought a lot about these things, and apparently, a less elegant way to tackle this problem is decoupling power harvesting and propulsion. Like, put your best suitable power plant on a boat, then conduct power to best propulsion (probably submerged turbine or something)

Can go directly upwind (no tacking required). Can also be applied to boats.
