Hi Mary -

On the 4.3, popping the offended rudder up and back down quickly works for me, though I usually have big eyes while doing it . A boardless boat is probably infinitely easier to keep moving through grass, because your hand never comes off the steering when clearing the rudders, even on the low side.

On bigger boats, I'm always the guy scrambling around as the skipper freaks out. The kelp forests in Santa Barbera were particularly interesting!
