Disco Winches
By Michael

Here are most of the innards from the big
48s--missing the drum and largest bearings.
After this I did our two Barient secondaries
and two Lewmar 30s on the mast.
The 1970s have long been maligned for their negative contributions to humanity, things like the Vietnam war, 20% mortgage interest rates, and disco. But what most historians fail to include in this list is our 1978 Lewmar 48 self-tailing winches.
Del Viento’s got two of them, one on each side of her cockpit. They’re big, they’re black, and they’re stout. Several times, fellow boaters have complimented them. I always acknowledged the compliment with a simple thank you, but I’ve always thought to myself: Oh yes, they are damn nice.

Indeed, without them Del Viento wouldn’t look half as serious as she does. Her coamings swell where the Lewmars are attached, to accommodate their big footprint. As a prospective buyer, these winches spoke to me: Just look at us! Nobody would put us on a 40-foot boat that wasn’t strong and ready for big loads.
I recently serviced them for the first time.

It was easy enough to start: nine Allen screws, three sets of three. They loosened easily and in turn released the top cap and both halves of the self-tailing cleat. I then lifted off the cast-aluminum drum to expose a solid bronze base housing the main drive shaft and two sets of gears fitted neatly at the bottom.
Now I’ve rebuilt winches before, different sizes and makes. To get those two sets of gears off (and to expose the pawls and springs between them), I had only to remove the vertical axles that held them captive. But for the life of me, I couldn’t see any way to remove these axles. Only after a long, difficult search online, having tried a bunch of key words and having waded through about a dozen online forum discussions on winches, and having returned to the cockpit several times to confirm what I was seeing, did I turn up a PDF of a tattered manual for our vintage Lewmar 48. There in that ancient record, in clear monospace, were instructions that validated the worse-case scenario I’d stumbled on in my online search: these gear axles are pressed in from the bottom and it takes a punch and a hammer to knock them back out, through the bottom. By design, the winch must be completely removed from the boat for servicing.

Isn’t that absurd? What were the 1970s Lewmar engineers and designers thinking? Have they never owned a boat? Has anyone else come across a design like this?
In the end, I recruited Windy’s small arms and hands to reach into the underside of our coaming and hold each nut while I loosened it from above. After completely cleaning, oiling, and greasing each winch, I re-bedded them and we reinstalled them.

Once I finished the first winch, I did notice the word England forged into the top. So maybe it’s not simply a 1970s thing, but a 1970s British thing…
After all, in America S&S designed Del Viento in the 1970s—and there was even Star Wars, Farrah Fawcet, and bean bags. But apparently, overseas it was the decade of IRA violence, the infamous 1979 Fastnet Race, and the Lewmar 48 winch that must be completely removed from a boat to be serviced.

The girls at Beacon Hill park near Del Viento. They love it there
and usually spend several hours exploring after their Monday
morning shift at the petting zoo is over.


  1. It gives me perverse pleasure, not to mention a good chuckle, reading your posts. Best wishes to the crew of the good ship Del Viento!

  2. Totem is also a 70s S&S design, and we are pretty sure most of the winches were original (we've replaced a few)... thankfully they don't all require complete removal for servicing. On the other hand, weeellll.... I guess we have some big jobs ahead of us before we contemplate the Indian Ocean next year. Yikes.

  3. There's a very nicely done tutorial on servicing Lewmar England winches at He has a whole lot of other how-to articles there as well. Every one we've used has been spot-on and very helpful.

    We have 7 of them to do this season.

  4. You must be getting down there on the project list if you are servicing the winches! Congrats! (We have yet to do ours, except for slathering some more grease in 'em.)

    Hugs to you all!

  5. Basic types of Winches include hand crank winches which are suitable for pulling in small or light items, and there are also high-powered machine winches which can be attached to vehicles or machinery to move heavy and bulky items.


Thank you for taking the time to comment; we look forward to reading your feedback. Don't forget that you may also contact us directly at (please type DEL VIENTO in the subject line)
