If you add a smaller self tacking jib to a cat that uses a large jib, how will it effect the rest of the boat. Center of effort? mast rack? weather helm?
The T's did it when they went to a self tacker.. might be a good question for that forum?
We have a mystere 5.5 (zack) that added a T rig, and self tacker (and 10' beams). He depends on his reaching spin for downwind more than we have to, but he does well upwind with his FrankenRig
