Otherwise you will get caught in irons. Don't know if its true on a large cat, but on a small cat, in light winds, you are better off to just jibe - 270 degrees if going up wind. I think cats are much easier to sail, as they tend to be more forgiving. I was never afraid to sail in tight quarters with the cat, where a mono can drift or be blown where you don't want it to go. The cat is always going to follow it lines.
The loads on a big cat are much higher than a Hobie and jibing to go upwind is going to be a real PIA to center the main, sheet it in hard and then handle jib sheets while you are losing tremendous ground to windward. Not to mention putting undue stress on sails and the rig. Big cats without dagger boards drift and slide a lot especially at lower water speeds. Look at the windage on the side of a modern charter cat. I would guess many times more than the surface area of your Hobie sail.
