Sharpening Turn Fin

[Terry Heddin]

Am told I need to sharpen the leading edge of my turn fin. Should I sharpen both sides, (like a knife) or just inner edge to the outside, or outer edge to the inside?

From outer to in

you always sharpen the right side only on everything. do your rudder the same way, skeg if you got one also. because the boat naturally pulls to the right so you want the outer edge sharp and not the inner or left to help offset that.
