Looking to buy: plastic cover/sheath to cover my shrouds up to 6ft up.

I don't know what these are called, but I'm trying find plastic sheath that I can put around my outside shroud. The shrouds are approx. 5mm and these "covers" would be 6ft long and just fit over the shrouds by the slit that goes down the length.


I've seen these on other sailboats, but not able to find them in any marine store, I don't know the name or term to do a search online.

Any info pointing me in the right direction would be appreciated.

Re: Looking to buy: plastic cover/sheath to cover my shrouds up to 6ft up.

I can't give you much info on sourcing or names, but my catamaran has them nearly the entire length of ~45' shrouds. These are ever so slightly oversized and rattle quite badly in cross winds, which gets rather noisy down in the hulls. You'll likely want to find a way to keep them from vibrating and rattling.

Re: Looking to buy: plastic cover/sheath to cover my shrouds up to 6ft up.

I bought some at West Marine some years ago, for a boat that still used wire shrouds. Seems like it shouldn't be hard to find.

I use a pvc pipe that just fits over the swage fitting and a cap with a hole drilled center at the top of the pipe. No noise and allows the jib to slide past. I have 4’ lengths but I’d imagine the same results with 6’. I’m sure there are better ways. That’s just my way.

Do not install tight fitting tubes. They promote corrosion.
SS corrodes in the absence of oxygen. Tight fitting tubes trap moist dirt, the moisture becomes stagnant (deoxygenated) and corrosion is the result.

Thanks Orion Jim.


Does anyone know if they still make the thin 1" (25MM) or so diameter ones with the caps that cover up the lower turnbuckle or adjusters?

Re: Looking to buy: plastic cover/sheath to cover my shrouds up to 6ft up.

We have (sort of) shroud covers on the outer shrouds of our new-to-us boat. They are suffering from UV degradation and are in the midst of slowly breaking apart and falling off in small pieces. They don't seem to prevent much chafe on the jib, and suffer from getting beaten by flogging sheets. When they finally disintegrate completely we are not expecting to replace them.

So a little loose so they can freely move (and not corrode) is the ticket.

Oxygen is the key. Even if you make covers larger than the shrouds, in theory you would need to ensure oxygen flow for best protection…

13mm dyneema is some big line for a 36' boat! If you want to cover it to prevent chafe, you can use "Spiroll," a soft PVC wrap designed for just that. I use it here and there on my synthetic shrouds. I wouldn't wrap the entire shroud with it, just the sections where chafe might/is occurring. Last time I bought it I just ordered it online from the manufacturer who can be found with a browser search.

Re: Looking to buy: plastic cover/sheath to cover my shrouds up to 6ft up.

Take note of boatpoker’s post. What he/she writes is oh so true…
Why do you want covers?
For aesthetic reasons?
If they’re snug fitting they grip the shroud and are pretty much ok to hold.
If they’re loose they spin when you grab the shrouds for support.
I got rid of all mine except an oversized one on the inner forestay that rolls to protect the headsail sheets when tacking.
It’s personal choice.
I wouldn’t bother

White PEX tubing. Cheap, easy to find and if you slit it with a utility knife blade, slips on readily and stays put.

I'm on year 2 with no visible degradation. When it deteriorates, I'll replace with shiny new. Did I say Cheap and easy to find?
And I can break out the nice varnished ash rollers when company comes.
Saves a bunch of abrasion on the new genoa sheets.
