I would give a lot for a good and workable design of such a gear.

When I was starting to build my own cat, I gave it a lot of thought, but never came up with something which could work in a bumpy sea and a striking brake.

I sail always single-handed and because I'm getting older, it becomes harder and harder to pull my cat without beachwheels alone in and out the water. And the limp and soft sandcondition on my spot makes that even worse.

So, any ideas?????????
