"1.7 Rigging and equipment

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 races."


Yes, Thanks Tony, was just going to find it but got distracted.

It clearly states that adjustable diamonds are allowed.
