Re: Topping lift loads?
I can only think of a few cases when the load would be greater than the weight of the boom and folded mainsail. I do sometimes stand on the main boom close and foreward, near the gooseneck when I first lifting myself for a trip up the bosun's chair to the masthead. There are also times when I tighten the main sheet with the sail down in order to keep my main boom stil in a chop at the dock or motoring. If the main is not snug with the sheet the shock load on the topping lift as the boom swings with a rock can be significant.
I must confess that I adjust my topping lifts on my main and mizzen booms with a half Duncan Yo-Yo passed through a loop. My half plastic yo-yo disc is likely my weakest link, but I haven't had them fail....
.... I replace them every five years due to UV damage.
