Herewith a better resolution scan of the SCANDVIK BUNGY Marine Shock Absorber. I made a zip on Naugahide UV protection sleeve.

Thanks, Dick, but still a bit small and hard to read. However, if you just Google “Bungy Snubber”, it’ll take you to the site of the manufacturer in Sweden, namely Aronowitch and Lyth. It’s a neat site with cool products. These wonderful snubbers are sold in the USA by Sailcare and by Happy Cove.
They look perfect as a mainsheet shock absorber.

SailCare had package of 2 for $17.50 (phone order only) – I bought 2 pkgs, with shipping to NJ, just shy of $42.
Happy Cove website: package of 2 for $30, plus $10 shipping.

I have 2 on my main sheet… they work well. Easy to install. and mitigate some of the shock in light choppy conditions.
I saw this post on the group this summer and thought these were a great idea. Now I am not so sure and wanted to pass this along.
I put a pair on a 5/8” dock line a couple of months ago. All seemed great when I installed them and they flexed as advertised. The line is a few years old in good condition. No unusual storms but there have been some strong winds; wakes from passing boats are not too significant here.
I noticed deformation yesterday and took these photos. The cover is chafed through at the bends but not through the core (yet). I replaced the line and will put these back on, but will monitor it closely. I will also experiment with 3-strand line.

Good catch. I was thinking of getting some of these. Looks like chafe could be an issue with these snubbers.

Hello all -
I installed a pair of these on my mainsheet in mid-September. The line showed no wear in the area, when I hauled Moustaches out at the end of October but I will certainly keep an eye on it. I’ve enclosed a photo of the snubbers in situ.
Nick - I can’t help but wonder if the type of line has something to do with this issue. Not, for one second, do I think that you are using “the wrong type of line” or anything like that. iI’s just that line is now available with different covers, different stretch, different cores, etc., etc. Clearly, your line took a beating. Interesting …

Like Ernie, I put two on my main sheet (purchased from SailCare). At the time I did note that the package insert/instructions had a warning about using Bungy on braided lines, or lines with cover. (I don’t have the insert in front of me, and don’t recall the exact wording). I used them for the 2nd half of the season, and my main sheet appeared just fine at the end of the season. Was pleased with the damping on the main sheet, and also found it twisted less with the Bungy’s affixed.
Neither the SailCare nor the Happy Cove website include this warning information in the product description.

I have two on my main sheet down near the deck to mitigate the slamming in light air. Been there for years and no wear noticed. However I do not think they defect as miuch as if the entire boat was hanging on them so to speak…
Good point, Thor -
I think that they are much better suited to a mainsheet than a dockline. I’d go with a conventional snubber on a dockline or at least 4 of these little guys on a single dockline.

My snubber, located on the turning block end of the sheet is about 14 inches long. It has been great all racing season having endured many a hard jibe. It shows no deterioration or cracking after about 8 months.

I think Ernie makes a good point: other line may be better. The 5/8 line I have is a tight fit, although the package insert says suitable for lines up to 20mm (~3/4").
To Tony’s point: the package insert says "Kontrollera linoma med jämma mellanrum … " — oops, sorry, wrong paragraph. Try this: “Check the lines at regular intervals since all compensators make a little wear. Occasionally move the compensators around on the line. Don’t use lines with an outside sheathing covering an inner core, which can’t be visually checked.”
So, I did not closely follow directions and just used the line I had. The pics all show 3-strand. But it does say it is suitable for permanent mooring. Most line damage comes from heat and that appears to be the case for me. The Bungys show no sign of wear.
I got these to experiment and I will continue, but with 3-strand and more Bungys. And I may check them out on the sheet. I still think they are cool, albeit pricey.
