So when the boat is up on the foils, it doesn't go upwind very well? I was wondering about how well it could point if most of the boat is out of the water, and most of the boards/rudders too. Not much left in the water to keep it from side-slipping. Now that leads to the next issue, if a foiling cat were to be developed, would it need a new type of race course? Instead of upwind, downwind, maybe reach back and forth over a longer course?
