If you want to start a race with the rig canted permanently on one tack then - yes!
Class rules state:
1.7.1 It is not permitted to adjust the following items while racing: the rake of the mast, the tension of the standing rigging, the angle or length of the spreaders or the position and height of the gennaker boom.
1.7.2 It is permitted to adjust the diamond wire tension while racing or to adjust the items named under 1.7.1 between the races.
For once I agree with Macca (I feel dirty
. I don't see anything there preventing canting. You can't change the amount of tension, but nothing prevents you moving the mast side to side without changing the tension.
And sometimes those rules are weird: Pulling the jib halyard pulls the mast forward. Does this mean I can't adjust the jib tension on the water as it changes the mast rake? What about when I'm solo without a jib up? The halyard on my boat is still there, can I tension it?
