Yeah, I've not really had a windvane "break", have had teeth marks show up on an oar, have had it collect sargasso (Aires) have lost and oar (stupid user) have busted an arm that I designed and installed (beta version), but the Vane's themselves I've not had any reall issues of.

Look forward to more of the details on your refit after the strike. And the two to three weeks of installation.... If you count only the hours maybe, but unfortunately that's not the only thing that counts when out here.
