Cookie Monster,
I've got another trick for righting the RC30 and it does not require shroud levers. I'll tell you about it sometime.
By the way, those shroud levers on your boat are a go fast device also. In very light winds and going downwind usually the mast rotation is limited by a tight leward shroud. The leeward side of the mast runs into the leeward shroud and this limits you to about half as much mast rotation as you would like to have. Open the leeward shroud lever and the leeward shroud goes slack and the mast cranks right on around parallel to the beam or even more. Now the mainsail and mast take on a much more desireable airfoil shape and you can actually feel the boat accelerate in light winds. Tighten the leeward shroud before jibing.
