The water start process may be more along the lines of clambering onto the boat as she is coming down onto her feet. Somehow or other, instead of falling into the water as it comes up, you hoist yourself onto the tramp. With spinnaker halyards and self-tacking jibs I don't see this as a simple proposition.
Picture the monohull sailors that can capsize/right their boats without ever touching the water.
When two up one person can sit on the leeward hull and swivel onto the tramp as the luff hull is coming down, this isn't to difficult if the timing is right. But I'm sure there must be a way of (moving) a Cat in a certain manner to help get her upright quicker? There again in light winds in zero waves you'll always be struggling unless you're 6'0" tall and 196lbs.
