Ce que couvre cette vidéo

Thomas Nilsson explains the function and adjustment of the boom vang and the traveler to control mainsail twist and boat balance.▶ 0:49 The boom vang adjusts the vertical height of the boom, while the traveler controls the lateral position.▶ 0:03 Tightening the vang pulls the boom down, closing the leech and increasing power in the upper part of the mainsail, which is useful for reaching and downwind sailing.▶ 0:54 Conversely, a loose vang allows the boom to rise, opening the leech and spilling power.▶ 0:54 On a beat, the traveler allows for finer adjustments to the sheeting angle; moving the traveler to windward pulls the boom toward the centerline, enabling a higher pointing angle.▶ 0:54 In heavy air, easing the traveler during gusts spills power while maintaining mainsail sheet tension, which keeps the forestay tight and prevents unwanted depth in the jib.▶ 1:52 If the boat becomes difficult to steer in gusts, releasing the vang quickly dumps power from the mainsail.▶ 2:40 Proper trim is confirmed when the leech telltales flow straight back or fold slightly to leeward.▶ 3:59
