Gooseneck fittings

Aeolus had a premature end to yesterday's race when the boom disconnected from the mast. A pin had sheared and I had no replacements on board - if it hadn't been so windy (F6 on the Thames!) then a temporary repair would have been possible.

It's a bit difficult to accurately describe what failed but it is a pin holding in place a cylinder inserted into a metal block that forms part of the gooseneck.

I've been told that the pin that failed is a seloc pin, or a slotted spring pin which expands as it is inserted. I can use one of these but wondered whether it was necessary or whether a simple split pin would do.

It is difficult to tell from your description what has failed. If you look at
Archimedes reefing attachment
there are three 'pins/bolts' which could cause the problem. None on Archimedes appear to as you describe.

I don't know how to post a photo into a reply, but have uploaded a couple to the group page.

These show the parts - the pin goes through the small hole in the metal block and secures the cylinder (that goes in the larger hole) inside the metal block at the pivot between boom and mast attachment. The pins prevent the cylinders from falling out.

If you look at this:
Archimedes reefing attachmentI think the pin you described has been replaced with a split pin. It was like that throughout the time I had the boat (5 years) with no problems. Perhaps someone can throw some light on why use the type of pin that broke?
I will have a look at my other boat Klipspringer next time I am down.
