In catamarans in light air, it's much better to overstand slightly than to short tack at the mark. So - don't get into this position. Port tack boat ducks stbd's stern, goes a boatlength or two, then tacks. Now they're on stbd's hip and in a controlling position.

If you end up in that position, the last thing you want to do is stall out. Slow down, let the weather boat roll you, then tack.

In catamarans, it's almost impossible to force someone on your hip to tack - as long as your boatspeed / pointing angle is comparable. Obviously, if you can point higher (and still keep up speed), then point until they get sucked into your bad air. But that takes a while.
