If it is about time to tack you need to be able to count. He presses AUTO on his autopilot, moves forward from the tiller, opens the ballast system cross-feed valve, starts counting, two, three, four, eases the mainsheet a bit, twelve, thirteen, fourteen, jumps down below and starts to heave the crates to the leeward bunks, sails, tool box, etc etc. Trim the sail in, check the main, watch the speed build, dive down below to finish moving the kit to windward, then get back on deck, check the jib, check the main, get back to the tiller and disengage the autopilot. Now he is steering again, catching his breath he can look around, spot the next windshift, and consider going through the whole process again. Its not surprising that the natural reflex of the average Figaro sailor is to aim to sail two tack beats.
Anticipation is all, along with a bit of fitness, strength and more anticipation.
