angled rudder cornering

[yipster]

fast or halffast gliding boats on propshafts lean outward when cornering, small boats more than wide etc.
dont think trimming flaps cornering is a good idea, but maybe there is automatic heeltrim?

without going to OB, heckdrive or jet would a angled rudder help leaning in i wonder?

it must have been done, what is there to say about it?

[marshmat]

Airplanes do it. Works for them. Of course they have ailerons to help, but the idea should be sound for water too.

[yipster]

came as far thinking of a flat plate on top of angled rudder
should look at airplanes

the thing that causes the lean it partly the final thrust vector, and partly the V of the hull. you're right to draw the comparisons with aircraft, find a model aircraft stability page. they will have an example as roll being a secondary function of yaw due to di-hedral. Or deadrise as we call it.

Incidentally, I have managed to perform various rolling manouvres with rudder/elevator gliders. so that gives you an idea of the coupling.
