A factor I didn't account for was whether I could reach the topping lift from the cockpit. The mast was down when the riggers installed it so they chose the length they thought right at the time. As it turns out, I can just barely make the stretch standing on the hump seat. Anyone shorter can not. Most of the time I just leave the lift on anyway, so it's a minor annoyance. Of course, if it had been too long we couldn't adjust the boom high enough. We went with dyneema and a snap shackle. This works out fine.
One 'problem' we do have is that, at anchor, in a good wind, there is a harmonic sound from the line, like a cello string. Sometimes I enjoy it as music. Other times, especially in high wind, it really howls and is quite irritating. I've experimented with a hack damper which drops the noise a little. I wonder if adding a soft shackle would help. I'm contemplating making something with an elastomer plug as an insulator.
Has anyone else here been irritated by this and found a solution?
