Provably the most gusty conditions at WK this year, square SW and 10k to 30k winds, super gusty and very on off wind. Used a 6.3m and 7m, SB W58 and iS107. The iS107/7m was the easiest and fastest in these conditions. I did struggle to fully close the sail in the gusts, hence the low speeds. Very busy for a week day, wa silly 30 sailors on the wall. Was fun.
