Just for clarification, the Fox 2 Up races are for standard mode Sprint 15 catamarans with two people sailing with main and jib. Trapezes should therefore not be used.
As ever, at Shanklin, we ignore the requirement for a short tiller.
I don't think this has been written down in the sailing instructions so it does not apply retrospectively.
The specific rule at Shanklin that allows two juniors sailing together to use trapezes applies.
Sailors are welcome to trapeze two up in Sport Mode races or cup races using the faster handicap.
