My boom and gooeneck slips out the of the kerf (below the point where the kerf is wide enough for it to slide out).

Has anyone had an expernience in making the kerf smaller (ie squeezing it back closer.

You will probably have some difficulty making the slot smaller. You would probably be happier with a fixed boom attachment anyway. Check with Catalina Direct for the mast and boom parts required. It shouldn't be much money, the result will be better, and you won't risk kinkng your mast trying to close the slot.

I agree with Al... Once extruded aluminum has been bent, it's already weakened--bending it back will weaken it much more. I never liked my sliding gooseneck anyway.

See http://www.catalinadirect.com/index.cfm?fuseaction=product.display&Product_ID=459
...for the Fixed Gooseneck.

Dave, I doubt that you will be successful closing the kerf, but on Calista I control the gooseneck travel with thumbscrews. Those little barrel shaped devices that ride within the mast kerf and that are locked in place with a thumb screw. Of course you must work to control the gooseneck above or below the mast slot. they won't work in the slot.

Val, it sounds like he's saying the mast slot is distorted (pulled open?) so the gooseneck pops out where it's supposed to stay in. "Sail stops" won't prevent that unless they hold the slider at a different position in the slot, which might not be ideal.

Right, David?

Yes that is correct. It poping out of the kerf. The slot stops will not help this.

What are the pros and cons of the fixed attachment vs the sliding attachment?

Hey David, have you heard the 08 nationals are at OCBC? We need to get this fixed! I vote fixed gooseneck. Look around the docks, sliding goosenecks are rare. If you have a cunningham on the sail it will never have any effect to go fixed. Honestly, I wonder if your gooseneck isn't messed up anyway, I cannot imagine a fully articulating gooseneck developing the force needed to "pop" the kerf.

Could it be because the traveler is behind the boom? Is it popping out when close hauled? Also (especially if you have a bolt foot) you may want to tighten the outhaul to pull the boom in. Then again, if you are generating enough force to pull the goseneck out, you'll rip the sailslide. Not much help, am I?

BUT, lemme ask my usual stupid question: could you find a bigger slide for the gooseneck (until the track opens even further, that is). <blockquote id="quote">quote:<hr height="1" noshade id="quote">Originally posted by Frank Hopper

What forces would cause the kerf to widen? Even if the boom swung around, wouldn't the stays prevent forward motion enough?

If you have a tall rig and ever want to use a bimini, do not go with a fixed gooseneck. Your boom will end up being fixed too low. Try lowering your boom so the gooseneck is below the point where it pops out of the slot.

Sorry, I missed the #6 part. I guess the tall rig didn't come on the scene until much later. If the boom always stops at the same point on the mast and that point is where it pops out of the track, then the fixed boom fitting upgrade might be the best solution for you.
