Fin Shapes
Hello,
So I've got 4 swing keels and two rudders to shape. I'm wondering about how water will flow over them, and what the best shape will be for each.
One part I'm confused about regarding the swing keels is where the thickest part should be, and how aggressively they should be tappered on either side of this line. My plan seems to show camber for a raised swing keel, which makes no sense to me.
Should I make the swing keels dedicated to one tack or should they be symetrical? There are two in each hull. Very fun to think about, but I don't really want to rebuild them later.
For the rudders, I'm thinking of putting little bumps on the trailing edge to make smaller vortexes, like a humpbacked whale's fins. Any thoughts on that?
Any thoughts would be greatly appreciated :)
