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?
Depends. Replacing a large overlapping jib with a tiny one is sure going to change things. But then you may play with the jib luff for example, making it longer going down all the way to the spi pole, and as such not losing that much jib area.
