Rick, about towing a catamaran.

I have been towed several times at sea by a boat and I towe my cat often on the beach flood-line with my tractor.
I've found an ideal system for that by simply modifying my hawaiian upright system, which is mounted below my trampnet.



All I had to do, is adding a shackle between the rope from the hawaiian uprightsystem and the elastic cord which pulls this rope under the tramp.
In that way the rope can easily be disconnected and pulled out.

It then forms a perfect bridle between the two bows!



The bridle is fixed at the rear beam on both hulls and goes along both hulls until it passes the bows via a padeye.

It towes on land and at sea perfectly. And it's always there and available.
