Re: Twisted mainsheet

Actually, I use low tech, plaited dacron with a linear core on my boat, rather than a double braided line or some high tech line. It is a little more friction than a smooth shell double braid, expecially since I wash the line the line in fabric softener. [IMG]Photobucket[/IMG]

Above is a picture of my cockpit showing my mainsheet which is 7:1 so any twist can quickly add to the friction.

I have seen this on may boats and just now gotten around to asking about it. It seems to increase the friction in the system and seems to be a bad thing.
Is there anything that can be done to fix this?
I have a similar main-sheet arrangement to you, but have a different block set-up.

I think my set-up is what others have been suggesting.

I don't get any sheet/block twisting, but end-for-end the sheet every season - hence the (modified) bowline.

Re: Twisted mainsheet

As a temporary measure I just move the bitter end forward. It looks a little better.

That's an improvement. Why not try orienting the aft block properly and fixing it there - stopping it's ability to swivel? I have a similar setup for my mainsheet and there is really no need for the blocks to swivel.

Re: Twisted mainsheet




Here's the diagram I was looking for.

This utilizes a fiddle block on the traveler and a becket on the block.

Does running the mainsheet forward to the mast like that add a vang component to it?

Interesting question! didn't consider that.

However, I think this illustration, distorts the distance that the blocks would be from the mast. ( not to scale).

It was the only illustration I could find of the fiddle block and the becket set up at the traveler....that I was thinking about for davids problem
