I know folks who use these for both WW boats and rec\touring boats as well.
Of course with a longer boat you will want to tie off the ends as well when
transporting.

Yes, I have been looking at these. There is one called the Stacker that
says it is for whitewater kayaks. Do they really mean shorter- length
boats? I'm not sure what the difference would be for transportation
purposes...
