I'm planning on trailering my 24 Seasport down the AlCan this summer and concerned about rock dings on the front of the hull. I thought about shrink wrapping but businesses here in town are not geared up to do this kind of work this time of year. Lashing a tarp to the hull is likely to cause burnishing on the gel coat. Plywood would seem difficult to secure and might create a hazardous situation should a piece fly off. Anybody that's got experience doing this trip or other ideas would be of great help or should I just tow it naked?
