Dang sushi, I didn't see the post over there until I just read this thread...

Slip numbers only mean so much and at a certain point they are gunna start to go the wrong way. If your boat runs 8% slip and 80mph is all she can do then good for you. If I am running 15% slip but am turning well into trips...well... then guess what... I am gunna eat your ass up and shit you out like a chocolate covered raisin.

The only time I really care about slip numbers would be comparing one prop to another on the same rig. JMO I have seen 5% on my hull and i have also seen 15%. even at 15% I am running 20-25mph faster then alot of boats can
