Not Sure Wich Winch to use

On Sundays sail my jib sheets kept cinching them self's to the winch?
I tried to put a snatch block on the toe rail to change the angle of
attack to the winch this did not seem to help? Any Ideas on the C&C 30
MK1 winch layout what winch is for what task?
Thanks for your help

Re: Not Sure Wich Winch to use

It looks like the winches on your coaming should work with your jibsheet lead without a turning block and without getting an override. The winches on the cabin top look like they should work with your spinnaker sheet without an extra turning block and without getting an override.

Re: Not Sure Wich Winch to use

Looks like your boat was set up for single handing and or racing. you have jib tracks, self tailing winches, rope clutches and more!
Harken's site may be some help,

Re: Not Sure Wich Winch to use

jib tracks not sure how to put thisinto play? Snatch block or just a pully? will this keep the winches from getting stuck? the bottom is cenching onto its self?
will the Rigging - Sheeting Angle cause the winch to faule?

Re: Not Sure Wich Winch to use

The winches on the cockpit coaming are called sheet winches, it looks like you have one set, which would make them your primary sheet winches. The winches on the cabin top are for most anything other than jib sheets.

My C&C 30 recollection is that the primary winches are positioned so the jib sheets can lead directly from the jib blocks (aka cars) on the genoa track to the primary sheet winch, and operate properly. MY boat had secondary sheet winches, so the primaries were further forward on the coaming. Hopefully your genoa tracks are long enough that you can lead the sheets for all jibs (150-130-110-90 or whatever sails you have) through the re-positioned cars. If you need to use blocks on the toerail for any sails, you'll lose about 10 degrees of pointing.

The only thing that should affect how the sheets trim is whether they are coming onto the winch at the correct angle, so they do not bind or override. See "angle" in here: http://www.harken.com/pdf/48.2_05.pdf. If the sheets are not coming at the correct angle, you need to put the winch on pads, or add turning blocks, but your C&C 30 may not need such changes. If the angle(s) to your primaries location is a problem, so with turning blocks, as a turning block ensures the proper lead regardless of car/block location.

A picture of the sheets under load would help identify what is wrong.

Re: Not Sure Wich Winch to use

Are you running your sheets direct from the sail to the winch? They are supposed to go to a block that sildes on the track on deck and then UP at at least a 5 deg angle onto the drum. The video still on the post above shows the sheet going down from the drum, into a block, the forward to the trim block and then up to the sail.

Otherwise 'overrides' will never go away.

Re: Not Sure Wich Winch to use

Just to pile on here:

If you look at the deck just forward of your aft winches, you'll see that stainless T-track -- that's where your turning blocks should be. The turning block is what keeps the sheet leading into the winch at a fair angle to prevent overrides. They may have been removed at some point by a PO, but may be hiding someplace on the boat.

See if you can find something that looks something like this:


It slides along the T-track, allowing you to fine tune the shape of your foresail at different points of sail.

Re: Not Sure Wich Winch to use

Looking at your photos it looks like you should be able to run your sheets directly from the sail, to the sheet lead block on the track and up to the winch. I found some photos of C&C 35-1's racing and that is how they are rigged (see picture below).

Also, to clarify Profin's comment, in U.S. parlance the forward block on the track, which the jib sheet is first led to is a jib sheet lead block. If there is a second block that redirects the jib sheet, that is a turning block. It does not appear that the C&C 35-1 uses turning blocks, just sheet lead blocks.
