Hi, folks -

The genoa sheets on my C250 are prone to wrapping turns on the cabin-top winches. It's clear that the sheets leave the sheet cars too high and reach the winch drum near the top - guaranteed to cause later turns to wrap over the first one.

The solution seems to be to replace the cars with lower ones, which I've got on order from WM. But has anybody else had this problem, or is it just me?

Thanks & regards,
Bill Arden

Bill, we experience the same thing. I read somewhere on the forum that puting a block under the winch to tilt it was a solution. I can't recall if the issue is related to the fore/aft position of the jib traveler cars.

Paul - Yes, fore and aft position of the car could affect this, I think. I'm going to try to solve it with a lower-profile car instead of putting a block under the winch (it's a brand-new boat, I don't want to break it! ) Will let you know how it works!

Bill, I had that problem also when we got our new boat. What I found is if I took no more than two wraps on the winch, rather than the three I took on our C25, I did not have the problem. The other thing I do, since I single hand most of the time, is to cross sheet the jib. When I do this I can wrap as many times as I like with no problem.

Frog - That make sense. Cross-sheeting (I presume you mean using the leeward winch as a turning block to send the sheet across the companionway to the windward winch?) might help the sheet find a better angle onto the active winch.

My '97 model came with low-profile lead cars kinda like [url="http://www.westmarine.com/webapp/wcs/stores/servlet/producte/10001/-1/10001/14200/0/0/genoa%20lead%20car/All_2/mode+matchallpartial/0/0"]this one[/url] and I've never had the problem you described. I think the low-profile cars are the solution.

I don't know who made the ones I have. I've checked a bunch of manufacturers websites and haven't found them.

I'm buying a pair of Schaefer 32-88 blocks (see WM or www.schaefermarine.com for details). It looks like the bottom of the sheave is 45mm (about 1.8 in) above the track, which should help a lot. They look a lot like the Ronstan blocks you mentioned.

Bill,
I started out with a different problem, but this solution might help (for under $20).
I'm working on a 2-line reefing system and installed a 2nd rope clutch.
The jib sheet would ride up on the new rope clutch and cross-wrap on the winch.
I just installed fairleads to fix this problem, but I haven't sailed with it yet.


Don't look to close, the boats in the driveway and this short line doesn't go anywhere.

I also installed cam cleats to temporarily hold the jib if the winch is needed for reefing.


I got the fairleads from West Marine -->[url="http://www.westmarine.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=10001&langId=-1&catalogId=10001&productId=25115"]Fairlead[/url]

Exactly!!! I do this while racing also since the winches are cabin mounted they don't hinder the ability to move around in the cockpit. On my C25 this did not work so well with more than one body in the cockpit, since the winches were coaming mounted, and cross-sheeting would put a trip line in the middle of the cockpit.

I have found that an easy way to avoid this, is to leave just <u>one</u> turn on the winch, then when you tack, pull your sheet in as far as you can by hand, wrap another turn or 2 on the winch and then put it into the self tailer. You can now "winch" it in as much as you want without it wrapping onto itself. If you put 2 or more wraps on the winch before you pull it in, it always seems to foul itself.

Just wanted to close the loop on this one. I finally got to try sailing with the new Schaefer cars(see earlier in this thread for reference), and the problem of riding turns is solved. The new blocks lower the sheets enough that we had no problems in 4 hours of work with full genoa yesterday.

I did, however, almost remove the stops at the aft end of the genoa sheet track before I noticed there were no stops at the forward end and that the cars would slide right off if I moved them that way.
