Thanks guys.
The rope trick sounds good, but the CoG of these Waves is very far back (behind the shrouds), and they will roll out the back just as easily without some sort of cradle/friction.
Instead of tying a line to the trax axle and going around the rear crossbar, extend the length of the length of the two ropes on the ends of the trax axle (like 10 feet each or something) so that you can rest the wheels at the bow and have the line wrap around the shroud and come back to the front crossbar. Then push the wheels under the hull to where they need to go, take all the slack out of the lines, and tie off to the front crossbar. The tension in the lines will keep the wheels from rolling backwards and the shrouds will catch the lines and keep the wheels from rolling forwards.
