The falling c - Clip

[odaydokay]

I'm up on the deck this morning fitting a new block for the furler line (yes, after 39 years, a Schaeffer block's wheel will seize, chip etc.) and I see something on the deck that looks like a broken part. Silver dollar sized and C shaped, but I figured iot must be an o-ring that broke and fell on the deck. Aftert some head scratching, it looks like it is an intact C clip (one of 2) that popped off the goose neck (Mine is the French made rig O'Day used in the 80's). So how did it fall out over the winter and should I just slip it on or maybe give it just small pinch in my bench vice first? Anybody had this happen? (I guess I am very lucky it landed where it did!)

Looks to me like you would be better served by replacing it.

I am curious who made the spar?

My 1988 O’Day 322 has a spar by Z-Spar.

Isomat made many of the spars for the pre-3 digit O’Days. Mine had c-clips on the gooseneck just like that. Mine would fall off when the boom was off if it was bumped the wrong way, but never when the boom was on.

Ok. I have never studied my gooseneck on my Z-Spar. Was curious if mine has the same C-clip that could fall out.

thanks for the background.

Thanks, all!
I think finding a replacement form a 1985 Isomat system might be a challenge and frankly I don't see much wrong with it. I think I will try pinching it just a tad and stick it back in. Not much to lose I am thinking. It had some grease on it which may have been the problem. The goosenecks on these can creak in the night so to speak and keep one awake so I shot it with some lube. That may have reduced its friction so it could pop out in one of our awful winds this winter. I did not have the sail up of course, but the boom would have been whipped back and forth I am thinking. Just speculation of course.

I have a hard time trusting a repair, if I haven't figured out the how and why of the failure, before I repair it.

Looks like D&R Marine has them - DR Marine Product Detail. Not sure if there’s anything wrong enough with yours to be worth replacing or not.

As for the noise from the boom swinging - I got in the habit of running the main halyard from the masthead across the bottom of the boom around the point where the mainsheet meets the boom, then over to the stanchion. By running the halyard that way and snugging the sheet the boom is held in place and can’t swing and make noise.

these are available as a commercially available product. No worries about the specific system. Below just an example, don't know if these are the exact ones you would be looking for.

I will try that. Makes sense. Very creative!

I agree with that. Turns out this thing popped out several years ago and I just stuck it back in, so will just try that again. Pulling the whole thing apart and putting a bunch of new parts is one answer but not my favorite. I do appreciate all the info from all of you, however. Will see what happens and report any "newsworthy" developments.

Mine came apart too. A couple of times. I think over the years the back and forth motion of the boom wears down the half balls shown in the D&R Marine link. I replaced mine and haven't had a repeat of the problem. For me, at $99, it was money well spent and only takes a half hour or so.

To keep the boom from swinging at anchor or mooring I just tie a thin line to one of the main sheet blocks and lead it port or starboard to an outboard end of the traveler and tighten it up. That is, I use the main halyard as a topping lift tigtened up against the main sheet and then the extra line to prevent the horizontal movement. Similar concept to what Davidsailor does but I don't like the line going across the deck to a stanchion because of the tripping hazard.

I like that idea too. Ours had the traveler behind the companionway without anything on the ends to tie to, so not really an option for us.

Thanks very much, Richard. You say 1/2 hour or so which is a lot nicer than i read elsewhere. What did you have to tear down/peerform to replace these "gonads and c-clips"?
