Light Air sail trim – question: (is this correct) sailing upwind the boat is not powered up so have the mainsheet out 1 / 2 feet – should you have on lots of vang and low draft in the sail at this point (as the wind is too light to keep connected to a full sail)??? – then when the boat powers up put weight out on the rail, pull in the mainsheet, release the vang a little and increase the draft in the sail????

Steve, that is correct. However vang tension shouldn’t need to be more than block to block setting (slack out of the vang line when sheeted in maximum) for underpowered (not hiking) and powered up (hiking). Sheeting out when the vang is set to block to block will slightly straighten the mast, and in underpowered conditions it will be effective in achieving better flow over the sail without adding too much draft. Once hiking, keep the vang at block to block, but ease some outhaul to add more depth
