I took with me two 40 cm wide speed boards, one Moo Custom and the new production Simmer Speed Demon 40 which I used to break the record. This narrow board size was the order of the day for most of the top riders, only varying a few cm’s either way depending upon the weight of the rider. The canal doesn’t really work until you get over 35 knots of wind and record breaking comes in at 45 knots for the girls and close to 55 for the men. So sail wise depending upon your weight you need a minimum of two small speed sails and the high-end carbon masts and booms to go with them.
I took Simmer SC speed sails 5.8, 5.5, 5.0 and 4.6m with the dedicated 100% carbon masts and AL360 Carbon booms custom made to a shorter length so they fitted these sails small boom lengths. Having said that 90% of the time was spent on my 5.0m. Some of the bigger guys took 6.2m sails but these were not really necessary as we were their to break records and you will never be able to get near the top speeds on sails that big. Quite a few of the guys were also using asymmetrical booms as well as you don’t need to worry about sailing back. But I have my doubts as to the benefits of these unless the sail is built from the ground up to not have boom support on the main batten. But its all about marginal gains and it may give you a bit more top speed with less wind resistance on the leeward side of the sail.
