Typhoon boom/mainsheet rigging problem

Post by Ron Ellis »

The narrow flat metal piece (I'm sorry I don't know its name) which is attached to the aft end of the boom on my Typhoon is bending. This is the piece to which the mainsheet rigging attaches and it is bending under the strain placed on it by the mainsheet rigging working against the sail. I have it rigged according to the diagram in the manual, but the bending does not seem right to me.

Is this normal? Any tips to correct it?

I have only been sailing it in average (<15 knots) weather conditions.

Thanks for your help.

Ron,
That tang should pivot freely around the bolt that goes through its center into the boom. If it is bound, it could bend (though it would take more force than I think should be generated by the mainsheet to do that).
So if it isn't free, that is the problem.
If it is free, it normally takes a tiny bend back toward the mainsheet block on the deck but anything more than that means something else is going on.

Ron,
The tang which Serge describes (as freely pivoting) will have more or less bend depending on the angle of the load of the mainsheet. I've seen Typhoons with various configurations of deck block(s) to boom. If you have a single block just aft of the cockpit (or a track) the bend will be minimal; any other configuration, like an additional run to another block further aft, will increase the bend of the tang.
If you can't bend it yourself with finger pressure, I wouldn't worry. If you suspect metal fatigue, replace it!
