The outhaul controls and shapes the mainsail. Ease the outhaul to increase draft and power up the sail. Tighten the outhaul to flatten the sail and reduce drag and heel in heavy air.
Typical boat length:
Small Boat: 22' - 28' (6.7 - 8.5 m)
Midrange: 29' - 34' (8.8 - 10.4 m)
Big Boat: 35' - 42' (10.7 - 12.8 m)
2:1 InternalSuitable for dinghies or small keelboats. A flexible cable shackles to the sail and enters the boom through a wire block. Placing a block aft of the cleat allows the crew to pull from a variety of positions.

2:1 Furling MainMainsails that furl into the mast are loose-footed and usually have a ball bearing outhaul car that rides the length of the boom. The outhaul starts at the car, leads through the clew block on the sail, back to the sheave on the car, and into the boom where it leads to a winch.

첫댓글 흠 실제 운영중에 일어날지 보르지만 메인세일 택부분에 얼마나 여유를 주고 묶느냐에 따라 감속 블럭이 좌우로 쏠려서 묶이게 되면 트리머가 무작정 당겨 아웃홀이 터지던가 혹은 반대로 아웃홀을 놔줬는데 풀리지 않던가 하는 실수를 할 수 이찌 않을까요. 축범때와 풀 범장할때의 포지션이 다를것같습니다.
혹은 최대로 당기거나 최대로 풀릴때 마커를 해두어야 하지 않을지요.
붐 내부에서 아웃홀이 최대한 나왔는데 더 당겨서 블럭의 손상이나 샤클을 손상으로 발생될 소지가 있지는 않을까요?
