I've sailed with my wheels up there on my 5.2 on several occasions 2-up in seas. While they did drag the water frequently, they didn't pose much of a problem or give me any cause for concern other than speed.

After the launching problems just trying to borrow the one set of wheels at the Sandusky Steeplechase (start at one point and finish where your trailer and the rest of your gear is at), I think I'll be racing with my wheels up there on the 6.0 this year so I don't have to wait for the one set of wheels. I think the 6.0 hulls are tall enough to keep them from hitting all but the bigger chop Lake Erie usually throws out.
