TOPIC: Twisting shotchord on a twin pole system

Twisting shotchord on a twin pole system 5 years 9 months ago #387

Hi there,
I've recently installed a new twin pole system on my boat but the continuous shotchord between the two poles running within the boom always seems to be twisted meaning the pole doesnt sit snuggly againts the boom when released from the snotter. I have trieduntwisting the shotchord and rethreading but its not long before the same problem occurs again. Any suggestions on how to stop this happening?

I think the problem happens because the lead in is not clean. The pole drops as it retracts meaning the shot cord is coming in at an angle. Solve that with a lead in front and you should be good.

Hi Mike
Thanks for your suggestions. I wasnt really sure what you meant except that the shot chord is definately coming in at an angle - but so are all those I see on boats that have the twin pole or even single pole system here. new shot chord fixes the problem for about two outings then the problem comes back as the elastic inside the casing seems to wind itself up. The Selden Carbon boom had a proprietary exit block for 1 pole and this wasnt ball bearing (the additional one we put on is) and so I thought making that a ballbrearing fitting might help - but it did in a marginal way.
SO considering your suggestion I am thinking about removing both exit blocks and cleaning up the cut outs so they look neat. Running the shot chord from inside the boom through the cut out to a cheek block mounted behind the cut out. The shot chord will thread from under the cheek block to above and then head to the snotter/kite pole (when cleated on the mast). That way the shot chord is never going to run over a pulley at an angle. Which is what I think you are saying? Good idea? Do you think it will work?
Thanks for your help.

I have been giving this some thought as I am seeing the same thing happen. It has not caused an issue but it looks like it could one day. Will what you propose work. Possibly, will it take much to try it? Should make it better. I think it is improving each part till you get it right. Shot cord type, length, leads etc all play a part.

Let me know how testing goes!

Hi there Mike.
Forgot to reply - but the issue is a little better now. Though I now just replace the shotchord periodically when it gets that consistent twist.
