Hello Everyone : I have noticed that the Lewmar 7's on my Catalina have become polished on the friction area of the drum. This makes proper adjustment of the Genoa near impossible when there is a decent wind. The winches work fine otherwise. I have been trying to come up with a way to " rough up the outside of the drum. Perhaps sand blasting will work ? The only other idea I have is to install an epoxy anti-skid material. I'm afraid that the epoxy would be too rough, & not allow the line to "slip" if I was trying to ease out the jib, in light winds. As always, thanks in advance for your
assistance.

Rich:

How many wraps around the winch are you using?

Usually I use two wraps. Three seems to get knoted up too easy when
trying to execute a fast tack . When I noticed the slippage, I compaired my 7's to others, & there is a difference to the roughness.

What size and type of line are you using for your jib sheets? Also, I would think a minimum of three turns is needed on the drum, two wraps on the drum seems a bit on the low side.

I would try scoring the drum with 80 grit wet/dry sandpaper.

Rich,
I usually use two raps on my wenches(winches) and they seem to hold. You may check around your area at machine shop they may have different media (grit and type) for sandblasting or shot peen to give you the texture you’re looking for. The epoxy method I don’t thank would hold up very well,

I agree with Carl B.

Just beware that the drums are chrome plated - at least all of the Lewmars I've seen on C25s thus far have been.

Ya, I can't believe the sheets significantly wore the drum down... Lewmar 7s don't have quite the grain of a 16, and carving it up will leave you with a mess. 3 wraps should do it. You can use 2 wraps while sheeting in on a tack (to minimize overrides), add the third to harden up, and cleat. Then take a wrap off to ease the sheets, and two off when you start a tack.

Rich,

Like the others I start with two turns and change that as wind increase/decreases. As the wind picks up I'll add the third wrap and as the wind decreases I'll drop turns. As I'm adding turns I do that to make small adjustments in the trim of the Jenny.

I have trouble seeing how the winch has responsibility for slippage. If the sail is trimmed properly, and cleated there should be nothing to slip. If it appears so, might the jib sheet be streaching? Another reason for slippage could be that some one is holding the sheet. In that case, I'd add another wrap and that should take care of the problem.

I have notice that are times when the forces on the sail are so great that I can't trim the sail when I crank the winch. When this happens I'll add another wrap and problem solved.

Hope this helps!

Rich,

It makes me nervous to think of sanding or otherwise scoring the barrels on the winches.

On Hey Jude I installed "Winchers". These are blue rubber tops that lock the jib sheet without cleating. In normal wind, three wraps are fine. When it gets up, four.

The downside is that you have to unwrap a couple of turns to free the sheet.

I prefer them to jaw cleats.

Carl,
"To the winch, Wench!!" A line from The Never Ending Story, and often overheard upon my yacht. Carl, you better get your winches and wenches straitened out. You might get in trouble rapping (wrapping?)on the wrong wench. I rapped on a wench 33 years ago and I'm sure other wench rapping would be frowned upon.
(Sorry. Just having a little word fun at your expense.)

Hello Again Everyone: Thanks for all fo your suggestions. My Jib sheets were replaced this summer, with 1/2 Wellington Rino-Flex Braided line. Perhaps it is the new line is too slipery. I just
don't remember having so much trouble sheeting the 150 in as I do now.
I will try the add a third loop when it starts to slip. We probably
do more racing than the average folks, & that is why I have been
hesitant to go to any sort of "self tailing device" . I'm also going
to mark the lines, so that I will not have to try to look up @ the spreaders to see if I am close hauled properly. As I have her on the
hard for winter maintenance, I'm just trying to make the time to
complete some maintenance while she's in the backyard. It sure is
easier to get things doen here than trying to remember all of the tools you need to do something once she's in the water ! Thanks again for all of your input !
