Re: Topping lift loads?
Unless you have a boom crutch or a hard vang, you are going to put some tremendous loads on your topping lift, to keep the boom from swinging around, when NOT sailing. Your main sheet is a larger diameter line and on a multi-purchase block and tackle system which you are tightening against the lowly topping lift. Nuff said?
