What this video covers
Nick demonstrates gennaker trimming techniques while sailing in 8 knots of true wind.0:17 To maintain optimal sail shape, the trimmer must constantly ease the sheet until the luff curls, then pull it back in just enough to keep the sail breathing.0:44 Over-sheeting remains the most common cause of reduced boat speed.1:24 When wind conditions require more force than a person can provide by hand, a crew member uses a winch to grind the sheet.1:01 If the sail fails to fill, the helmsman bears away to open the wind angle.1:12 Conversely, if the sail is shadowed by the mainsail, the helmsman heads up to increase apparent wind speed.1:37 In light air, the boat can sail as high as 90 degrees to the wind, but in 25 knots, the optimal angle shifts to between 120 and 140 degrees.2:29 Trimmers must balance sail speed against the necessity of maintaining a direct course to the mark.3:20
