CA! You aren't talking about a surf style board are you? Your buddies would shoot you!
I have never heard of anyone customizing a skim style board. Are you holding out on us?
Not to bad mouth Phase 5, they put a quality board, if not overly innovative for wakesurfing. There are a TON and I mean a TON of skimboards on the market. The uber-talented skim boarders ride behind the boat without the fin. If you remove that single attachment, there must be 80 different manufacturers out there and hundreds of different designs. I've seen what appears to be designs that would be better suited for wakesurfing than the tried and true Phase 5/Zap/Vic outline. Does anyone have any input on a non-traditional skimmer being used behind the boat?
