The S26 part wasn't too bad... the G42 part was interesting.

I can state with certainty that a C25 swinger will heel nearly 10 degrees in a 42kt (about 49 mph) wind gust under bare poles.
(fortunately, whilst at the dock)

Also fortunate is that the C25 has a highly redundant rig. While checking the boat, I noticed that the backstay was loose.

Tightening it didn't have much effect. At that point I noticed that the forestay was also quite loose... investigation revealed that the turnbuckle had completely unscrewed itself, probably from the vibrations induced by the wind howling through the rigging.

The hanked-on sail (in it's bag) was the only thing holding the forestay in place... and had also served to conceal the loose turnbuckle.

Needless to say, getting it screwed back together in those conditions was challenging... even in the marina. At sea it would have been nearly impossible to do by myself.

I think the next upgrade is replacing the old tubular turnbuckle on the forestay with an open style turnbuckle that can be safety wired.

I did go ahead and buy the Catalina 250 turnbuckles, They seems really funtional and nice. The are very cheap. $27 buys you the brass open turnbuckle, a SS collar that covers the turnbuckle to protect against chafe, a "T" bolt, the "T" bolt shackle, the shackle clevis and several cotters.

Recently I have seen some C-25s that did not have lock washers on both sides of the turnbuckles. When the stays are alternately tensioned and relaxed as you tack back and forth, turnbuckles will occasionally loosen. Also, the ends of the screws have holes in them, and, if you have open turnbuckles, you can wire them so they don't loosen.

This is the main issue that makes closed-body turnbuckles one of the worst ideas in sailing history. With open-bodies, you slide a bronze cotter pin through the hole in each of the bolts and wrap it back around the body of the turnbuckle. It's good for the next ten years, if you choose to leave it there. Lock nuts are almost sure to let go--if yours haven't yet, one will. I will never own another boat with closed-body turnbuckles, except long enough to replace them.

Good point DAve. As I read Clam's original post, I wondered about wiring the turnbuckle. And, at the end realized that his was a closed turnbuckle.
