I plan on adding mucho downhaul and am afraid that the little "V" hook won't be strong enough. I guess that i could have a heavier one made though.

As far as the rotator, Murrays and Catsailor only sell the Hobie style rotator. I would rather use the front mount system that NACRA uses. It seems simpler to install and use. I dont have a grommet in my tramp like the miracles, and I assume thats what I would need to make it work.
Then again I could be wrong.
