    Posted: 17 May 2011 at 9:30pm
We went down to check our boat a couple of weeks ago after a few days of strong north-easterly winds which blow staight into the harbour where were have our mooring.  The boom had become detached from the gooseneck, dragging a few of the sail track cars with it.  It appeared that the split ring, which went through the end of the pin at the gooseneck end of the boom had failed, and I found the pin at the foot of the mast.

I tried to buy a more robust split ring, but I was unable to thread the only one that I felt might have been up to the job through the hole in the pin.  I have therefore used a split pin (one of the "spares" our rigger gave us when we had the rigging renewed last year).

Is this a common problem, and have I done the right thing using a split (cotter) pin (which feels a lot stronger) instead of a split ring?  We are off to the Channel Islands and France at the end of the week, and I would be grateful if any of you who know about these things could reassure me that I have not done something that might make for a nasty surprise mid channel!

The boom is a Selden one with reefing lines running through it and the sail is fully battened, dropping into a stack pack with lazy jacks.

Many thanks,

Nick

Split rings are prone to falling off.  You can try to secure them with a bit of rigging tape or a dab of silicone.  cotter pins, when properly installed, are nearly fail-safe, but they can catch on sails or your skin.  So it helps to tape them as well.

My poor wee brain rebelled at the idea of using a "cotter pin" which to me is a solid, usually tapered, pin to hold parts tightly together but the gnomes of Wikipedia tell me that the sceptics use the term to cover split pins. 
There is no axial load on the pin so all you require is something to stop it falling out.  You were lucky to find the pin!
