Crew clears the c/boards by lifting them up when you go off the breeze....... skipper can kick up the windward rudder on each tack or gybe.

When sailing on a very weedy patch off water we normally run upwind with the windward board and rudder up and swap when we tack.

Downwind we bring both boards up on a non spinnaker cat or just the windward board on a spinnaker cat.
