Those numbers are similar to what I’ve been using. The original settings when I bought the boat were so low that the downwind shrouds would flop around loosely!
However, when tuned up properly, I started experiencing mast “pumping†in a fore-aft direction whenever there was significant wind abeam of the boat. This usually only happens when tied up in a slip, although I have experienced it when motoring in a crosswind.
I’d be interested in hearing if you have anything similar happen.
