pressure of the foils on the stay at the point where the sheets come off the
wrap.

Thinking about it since, I can't believe it would be an issue on a new rig.

If the backstay was slacker than it should have been, and the roller
furling slide break-point wasn't bolted tightly, the result could cause
the furling slide to v-bend at that point. Then, when unfurling/furling
often, caused the break to happen.

Basically, bad installation.

All roll-ups are, by definition, bad installations.

Zac's forestay snapped 10 foot above deck. Anyone care to venture why

This was new rigging and inside a roller furling.

cause he is trusting wire.
the boys doing a good job of it so far. if he fixes this little
problem he will do fine.
problem i have is he keeps going into port for fixes he could do at
sea.
so what a bit of rigging broke splice it and move on. would take at
worst a couple of hours.
sounds like the boy has a baby sitter.

Tell us how you would 'splice' 1x19 wire...


just like you would splice a single yarn in real wire rope. you unlay
and bundle the outer strands so you got room to work make a round
sennet with the inner strands then make a round sennit with the outer
strands around the inner. in effect you are makeing a chinese finger
trap the harder it is pulled the tighter it gets if you really want to
add some gorilla to it you slip in a bit of copper solid core in the
inner sennet. an eye slpice is essentually the same except the inner
core is woven into the inner core if the standing part of the eye the
strands are relaied to the splice then the outer is made in the same
round sennet around the whole cable. clap a seizing on it and your
done a simple soldure and a terminalpacked with silicone caulk would
be the trick for the electronics.

its not real hard you go up the mast and uncouple the damn thing at
the top, uncouple it at the bottom, unfurl and do the splice. reverse
the process tension as needed. its wire rope not brain surgery.
ya'll ever heard of a bosn,s chair? it gets you aloft with a marlin
spike so you can take the little pin out of the shackle a riggers
helper makes it a bit nicer but your pockets will do.

i was thinking of being as much of an asshole as you all are. but my
wife pointed out that some folks may have never actually done wire
rope splicing and it is a diffrent animal than most rope work.

It's very easy to figure out why it broke ten foot above deck. Wind the
damned sail up and that's where the clue and sheets end up. Any rocking
and rolling of the boat creates a stress point right there. Stainless
steel work hardens and crystallizes when bent back and forth.

This quite a plausible proposition on the face of it. I don't put much
tension on my sheets when stowing and this is probably a good reason to
continue that practice. I rely on either multiple rolls and/or a sail tie.

I've never heard of a headstay failure at this point though. Has anyone
else?

How often is he going to furl the genny with tensioned sheets on a
"race" around the world? Most likely, he's been using that sail a lot,
hasn't furled it much. If he's furled it, he'll have been using the
Yankee so not tensioned the Genny sheets.

IF it's 10' up, I suspect there is/was a joint there. (or MFG defect)

IF, as a magazine report says, it was at the chainplate, I suspect the
cotter pin keeper first, a high-percentage cause of masts going down.

Tug boats sure as hell don't discard that 1/2 mile long wire, just
because it parted. Splicing one does not sound like much fun.

it's not to bad. most times it takes a couple of hours to get it done
right.
