I plan to transport my MC 16.5 on the roof of my Tahoe this Friday. The trip will be 80 miles and about 30 miles will be on an Interstate. This is a one way trip. I plan to use foam pipe insulation over the cross bars on the roof rack to protect the hull. I will also use the same type of foam insulation on the ratcheting straps where they cross the hull. Those straps will secure it to the roof. Does anyone see any problem with this setup at 65-70 MPH? Again, it is a one-way trip...the boat will be left at the lake.
