Not really, no. The C2 and the Viper have gybing boards, so they slop around in the trunk a lot. Double check that the trailing edge of the trunk is smooth, sometimes there's excess glue that oozes out there and it doesn't get taken out perfectly. A small file remedies this. Unless the board had chewed into the hull a bit, then you need to fill and file the slot made by the board. I had a new viper maul a set of. boards because I never checked it before I put it on the water because of excess glue at the bottom.

The carbon trailing edge looks sweet, but its a mother to make look perfect again. One set of my boards are a solid color now, I need to make my other set, and the rudders match.
