Don't be fooled into believing hook should be removed. It may result in higher speeds but you may also lose some handling characteristics. Nothing worse than paying someone to make your boat worse ?! If the hook is real bad I'm sure some could be removed. I'd definitely do some research on hook removal. Make sure you take you boat to a competent establishment. Don't use the neighborhood autobody technician.
I've also read that just sharpening the transom/hull edge can be beneficial ?
