I guess the problem is how sailing judges define "kinetics" and punish the use of it.
I don't think that proper weight distribution is considered to be kinetics. Moving inboard and outboard, fore and aft to keep the boat balanced is just maintaining proper boat trim.
Lasers are not allowed to do what judges consider to be excessive tacking upwind, because they get an additional thrust of speed out of each tack. This obviously is not the case with catamarans.
However, I do think that catamarans can pick up some speed and distance by jibing downwind -- and I mean jibing more times than is necessary for wind shifts, tactics or getting to the mark.
I don't know about with spinnakers, but main only or main and jib, if coordinated properly, I think you do get an additional forward thrust from a jibe, just from the impact of the main flying across the boat.
Is this kinetics? Or am I just plain wrong about jibing helping speed?
