Siracco 15 gooseneck repair

I just bought a Siracco 15:
Should I Buy 1975 Sirocco S-15?

It's a great little boat. I had fun sailing it however, the goodneck broke. The boom apparently will roll so the sail can be rolled around it. I definitely need to research that. The design dictates a single bolt exiting the end of the boom. That bolt broke (see pictures). I haven't torn apart the boom yet to see how it works.

The hook attaches to a metal loop that attaches to the track on the mast.

Anyone have any information or advise for this repair?

Pull the duck tape off. There are probably some screws or rivets hiding behind the tape, or maybe not.

Pull the end off. The eye bolt is probably double nutted behind the end cap.

Find a compatible eye bolt, put it back together.

Welcome to the joys of owning an older boat, stuff happens. ;)

Go sailing.

I spoke to the former owner. He affected this repair last year and it was done two years before that. This means that either it isn't being repaired properly or it's just a bad design.

My plan right now is basically to replicate the same repair so I'll be doing this again in a year or so.

Here is a photo he had. This is not the correct arrangement, however. He must have fixed it after taking the picture.

If any one has better ideas, I'm open to them.

Here is the exploded view:

The new bolt being installed has the eye. The old broken bolt still has hardware on it.
I replicated the setup. So, it will break again...

I might reconstruct with a larger bolt and just forgo the furling ability of the boom.

Your setup reminds me of my previous boat, an O'Day DaySailer II. It had a rolling boom as well. I can't tell from the photos how the gooseneck attaches to the mast, but I wonder if this part would be a more reliable replacement:


If you think it might work, give Rudy a call at DR Marine and he will answer any questions for you. I'm certain he would even provide the measurements to ensure it would fit your boom and mast.

Wow, thanks for the info.

If it was mine and OEM parts were not available I’d be looking for a higher quality eye bolt, I’d also see if I couldn’t find a way (drilling or tapping) to accommodate a larger eye bolt as well.

That is probably what I will end up doing.

As for another idea ... one doesn't have to have a boom that can rotate to wrap the sail around. With a 6-ft beam (5.9-ft), frankly, you're probably never need to reef the main that way. The drawing in a previous link showed "mid-sheet" sheeting of the boom so to wrap the sail around the boom the sheeting will have to be dealt with and changed to end-of-boom sheeting. A potential bit of a pain. A slab reefing system might be easier, faster, and have better sail shape.

So, Plan B: IF you happen to come across a fix-it for a non-rotating gooseneck, go ahead and use it until you find the rotating one.

The picture by the previous owner of the gooseneck setup shows the "ear" (for lack of a better term) on the boom gooseneck facing down. It is possible that it should be for the mainsail tack. But maybe also for the downhaul of the gooseneck but I don't remember seeing a cleat to tie a downhaul off to.
