That's what I was thinking, but I was afraid to voice it. If that's
the case, that the deck is having problems, it could take a lot
longer to get it fixed. Fortunately, we have insurance for just
this sort of thing.

The bolts pulled through the deck? That's what I read. If true, either
the deck is structurally inadequate due to rot, deterioration etc or
the backing plates/reinforcement was inadequate from the start.

Can't see much of a solution unless people want to second-guess the
designers WRT structural adequacy and then where do you stop?

I think if it was done right, it wouldn't be too bad on the cabin/people.
Of course, this was a donated boat from years ago. Maybe we can
claim the lines fouled the prop and did damage to the A4. :-)

A keel stepped mast and chainplates on the hull is a stronger rig, but
the first interferes with internal accommodation space and the second
reduces pointing ability so - you pays yer money and yer takes the
consequences.

Has anyone experienced this? I'd especially be interested to hear
what happened, how you reacted, and how you might have
prevented it from happening.

Also, if someone knows of a way to prevent the following from
happening, besides using regular maintenance, inspection, and
replacement, I'd like to hear it.

Fortunately, no one was hurt, and the boat wasn't damaged other
than the obvious.

The skipper, S... is an experienced sailor and a former student.
The only thing I can really think to criticize him for would be not
having a backup handheld VHF.

"Skipper: S... (male)

Crew: L... (female), N.... (male), R.... (female)



Departed Clipper Harbor ~12:00 noon and motored direct to Ayala Cove.
Finding no open dock space, we raised sails and hove to behind Pt.
Campbell
for lunch. ~2:00 we resumed sailing off Bluff Pt. SE past Angel Is.,
then
S towards Alcatraz Is. By 3:00 we were beating SW towards the Gate into
a
~15-20 kt. wind, a ~3 kt. flood, and medium chop.

We had completed 3 tacks and were proceeding with R... at the tiller,
S...
in the companionway, and N... and L... in the cabin, when there was a
loud
cracking sound, followed immediately by a loud bang on the cabin roof.
I
could see that R... was disturbed and surprised; by the time I turned
around
to look forward over the cabin top, the mast and both sails were already
in
the water over the starboard rail. No one was hurt. I asked R... to go
below while I looked around.



Immediate damage assessment:

The mast was snapped off completely at the base, with only the twisted
mast
step and a broken bit of wire sticking up from the cabin top. The mast
was
hanging down into the water with all rigging apparently intact:
mainsail
and storm jib. One of the starboard stanchions was poking through the
foot
of the mainsail, catching the boom and keeping the rigging from sliding
over
the side. The base of the mast was sticking up over the cabin top and
sawing back and forth as the hull rolled with the chop, but it didn't
appear
to be going anywhere. We had been on a port tack (heading towards Angel
Is.) at the time of the collapse, so the rigging had gone over the
starboard
side. Acting as a sea anchor in the face of the wind and current, we
then
swung around with the rigging to the SW and the bow to the SE. This put
us
across the chop, and the boat was rolling strongly. A 360° look showed
no
nearby traffic and lots of sea room.



Cause:

The cause of the collapse was immediately apparent - the stern-most of
the
three bolts that hold the port stays was sticking up out of the deck
with
its top split open. All other shrouds and stays were still attached.



Response:

With no imminent threat, we all caught our breath in the cabin, and I
called
pan pan pan to the Coast Guard a few times. It took several minutes of
fooling around with the radio before we remembered the antenna was
mounted
on top of the mast. We did not have a back-up handheld radio.
Fortunately,
within minutes the powerboat Rubicon (looked like a father and a teenage
boy) came by to see how we were, and they radioed the Coast Guard for
us,
then took up station-keeping nearby. With the wind and engine noise we
were
barely able to communicate.

The Coast Guard Auxilliary vessel Silver Charm showed up in about 10-15
minutes. After confirming that there was no medical or other emergency,
they circled us and then came in close enough to communicate with us
through
a megaphone. I requested assistance getting the rigging up on deck with
the
idea of salvaging it. The Coast Guard indicated it would be too
difficult
to carry in the chop and to dock, and asked us instead to cut it loose.
As
the mast was by now hanging almost vertically down off the side, I
decided
to comply. We had a cable cutter in the toolbox in the cabin that I
used to
cut the shrouds and stays, working clockwise from the port (downwind)
shrouds. In the process I also undid the stop knot in the end of the
vang
sheet so I could pull it free of the cabin top, and I undid the main
sheet
and pulled it free of the boom tackle as the rigging disappeared into
the
deep.

Once I was sure that we were clear of all lines, I started the motor and
we
headed back to Clipper Harbor, escorted by the Silver Charm. We made it
back to Richardson Bay without further incident, though with all the
bouncing and rolling and wind, we were soaked to the skin by the time we
docked. The Silver Charm crew also tied up, and they came over to talk
with
us and give us the Coast Guard contact information."
