Let's not forget that there is the bad mojo you get from not putting your
boat up properly. The bow always get pointed forward and the boat is always
deck up for a sea kayak. Deck down for a WW boat so that it can rest.

Seriously though. My deck is too high to car top the boat deck down. It
would hit the roof. I like the J-craddles any way. The boats are much
stronger on their sides.
