Boom failure

Postby mattconner227 » Sun Feb 03, 2008 7:50 pm

On my second sail today and my boom failed just behind the kicker plate whilst sailing upwind.
Is this a common/known problem as it appears the very latest booms have additional build there or was mine just badly made.

Cheers

Matt

do you have a knot in your mainsheet? the boom can fold around the shroud if you don't, but this would happen downwind, that is why new booms have extra reinforcment and protection plates on the sides.
I have not seen one break upwind before.
Like Rick says Call Dave.

Good shout - everyone should have a knot to stop the boom just short of the shroud.

You can see the know in this shoy where the rope colour changes ...

Broken Boom

Postby bdu98252 » Mon Feb 04, 2008 6:14 pm

I broke my boom upwind at East Lothian last year however the boat was fairly old and so I guess it was just its time to go. It was wavey and it went when I pulled on a bit of kisker after the gun.

It's not unheard off for the boom to break upward behind the kicker bar. Latest booms have been heavily reinforced so the issue has been resolved. How old's the boom?

It's under two years old and looks as new (well, it did), it failed by folding upwards behind the kicker, whilst sailing upwind. It shouldn't ever hit the shrouds because it's got a knot it the main.

It's going back to Selden to have a look at so we'll see what they say.

Aah well!

Cheers

Rest assured whilst it is never pleasant to have such a breakage, particularly on you first outing, there have been very few such breakages in the class and the overall product, spars included, usually have extremely good longevity. A few masts have gone on occasions but rarely booms.

The good thing is that our nominated class insurers, Noble Marine, know this too and, therfore any claims are handled very fairly and speedily.

It should be remembered that whilst carbon is strong it is not overly impact resistant - so as an aside be careful not to drop it if putting the clew strap on and, always remember to pad your boom out when travelling, especially if you are looking to pack stuff like a tool box under the cover!

Good luck in getting back out on the water speedily and, I look forward to seeing you at the Nationals in June.

If it's 2 years old it wont be the latest spec. If you are going to Selden get them to check it has been sleeved correctly.

for anyone wanting cheaper progrip, buy direct from the supplier to the marine trade:

foolish folk at LDC left the manufacturer's sticker on my last batch of progrip, interesting how the sheet price is significantly cheaper from a 'non-sailing' source.

Progrip over-kill, but it does help keep me on my toes and not on my arse....

Matt My boom failed in the same place in mid summer 2006, boat was three years old, so presumably boom was. Sten said he had suffered a similar failure some time before. I phoned Proctor (Selden) who said I must have been reaching with the kicker on and overloaded it. I bought a replacement (one of those without the additional reinforcement)!!
