I have used the doelfin and currently we just put a stingray fin ($48)from West Marine on the new Zuke 140 on an 18SF. The planning speed dropped nicely and the fin does lift the stern up on take-off. There is no noticeable digging-in at turns and the extra side to side wing length vs. a more narrow one should only improve it's function. The narrow plates work great just different.
