is there any other boat out there with a rudder that is raked so far forward.., that isn't directly behind another surface?
usually, forward raked rudders are attached to, and immediately behind, part of the keel.
i wonder if there could be any surprises in the way it behaves, arising from this arrangement.
probably it doesn't matter.., but is there another example of this geometry on a sailboat.
forward raked fins were not a huge success on windsurfers
I'd bet that hydrodynamically, forward rake or aft rake is the same...shouldn't matter to the water one way or the other. Aircraft have looked at forward swept wings as a means to keep the outer wing panel from stalling at high angles of attack as the airflow tends to attach to the wing and travel in the direction of the sweep. Problem with aircraft was keeping outer wing panel from flexing and inreasing the AOA out at the wingtip negating the effect of the forward sweep.
On a sailboat, forward sweep might keep the bottom of the rudder unstalled while the top is stalled, but not sure it'd be enough of an effect to be notable/prevent the boat from rounding up, etc.
