"To finish first, one must finish,first"

good points on component inspections.

Not sure which platform you'll be using (18, 20, other) but individuals with your type of boat would likely have specific info on what to look for. I know there was some discussion on shroud base corrosion within the deck (and unseen) from water sitting against the stainless in an oxygen-free environment.

I recall someone lost a mast because they had taped up the chainplate and over the months the moisture in there corroded out one section. Thankfully a quick fix (no damage to mast or shroud) with a spare part.

Spreader connection(s) and shroud/spreader area need a good look-over. Tie the shroud to the spreader end to avoid the spreader moving vertically in a nasty wipeout or other calamity.

Also mentioned in the forums here was the two-side welded rudder pintles. Early versions were welded on one side (top I think), and they did break off at the most inopportune times.

The rubber elbow on the rudder arm was my undoing on a shorter race...

Spin halyard/tack blocks might need refreshing, as long distance spin legs will put a lot of wear on the bearing surface (even if it's not a lot of hoisting/dousing) which could cause block failure or excessive line chafe.

The spare traveler is an excellent idea and it's totally out of the way until needed. An extra batten or two may be nice to have as well in case an on-water (or deserted beach) replacement is needed. I think Les taped one to the boom?

A thorough review of your personal equipment is a good idea, as well. Harness buckles, straps, etc can cause major issues if they decide to let go on a long haul in poor conditions
