Chafe Protection Ideas

Thinwater, is that tubular webbing the same as jack line webbing?
Thanks,
Erika

I'm not very sure about jackline webbing, as more than one type is marketed as such. 2-inch, 7100-pound test, nylon, tubular. Very smooth.

I just read an idea for a make shift chafe guard i had never heard of and thought this would be a good thread considering half the eastern seaboard is buying up all the chafe gear, someone is probably going to have to get inventive.

Of course the fire hose from the local fire department is great.

Reinforced water hose ( but can heat the line up)

Just read this one, canvas scraps with lots and lots of duct tape.

Any other ideas out there that you have seen work?

Good luck to all,

Someone made a study of how lines failed during Hurricane Katrina.

One of the most interesting (to me) findings was that although nylon can make great dock lines because they stretch, the kind of extreme stretching that happens in a hurricane can actually generate enough heat that the line melts and fails.

They also found that when garden hose was used over nylon to prevent chafe it accelerated the melting because the hose kept cool water from hitting the line and cooling it down.

They found that things like toweling made the best anti-chafe because it allowed the cooling rain and salt water to continually bathe the line.

Based on this information I bought dacron, which doesn't stretch as much but doesn't melt as easily, and in a hurricane I'll wrap the pressure points in toweling.

I had a spring line rub on a piling last night in a storm and this morning that spot was extremely warn. It was an extremely old line from a double-line roller furler. Might have been made of natural materials -- just not sure.

I do not believe there is anything better than leather for chafe protection.

"I do not believe there is anything better than leather for chafe protection."


I thought so too. But let me explain why that is generally wrong.

Case one. Sew leather to a line and rub it back and forth over the edge of a concrete dock or worse, a rough bit of metal. Yes, the leather will resist very well, but eventually, within a few hours at very high load, it will wear through.

Case 2. Slide a bit of nylon webbing over the line, but only secure it loosely at each end and have it bunch up a bit in the center, or only secure it at one end. Basicially, it should floating on the line. Place it across the same edge as above. You will see that the webbing catches on the roughness and does not rub. The line slides within the webbing without friction.

It's like chosing between bamboo that bends and oak that snaps. It is also the reason wheels (with bearings) outlast sledge runners that slide on the ground.

Properly installed (always a catch) webbing chafe gear will outlast the line every time, and I have been using it for over 20 years. The trick is that the webbing must be attached in such a way that it becomes fixed to the abrasive object and the line runs within it.

Read an interesting article from Club Marine insurance in Sydney, that they sent out to many owners after a nasty electrical storm went through Sydney harbour a few years ago. A large number of boats broke free and caused quite some damage.

After the storm, together with a professional mooring operator, they investigated the moorings from the damaged boats. They found that many had used some sort of plastic tubing (garden hose etc) as wear protection, which had become brittle after deterioration caused by UV. The tubing had disintergrated into longish type splinters, and when subjected to the cyclic loading from the wave action, it actually served to accelerate the failure of the pendants.

I wonder about a product called Rhinohide. As wear protection, that stuff is almost indestructable, which is why we use in the industry I am in. However I can see the potential to retain the heat created by the pendants under heavy loading, if they are fully enclosed. I would suggest creating small openings (15mm?) at regular intervals for cooling.

Just my 2c.

One of the best line protection stuff is a fireman's hose.

One of the best ways to protect your line against chafe is to pay attention to the way line is led through areas which will chafe. A sharp turn around a fairlead is an area of expected chafe!

I always thought a woven hose like firehose leaks some water so the hose wont burn through in a fire.
the same idea would help keep the lines wet if rain and wave water can soak thru the hose and keep the lines from melting when stretched.
some testing is a good idea as firehose has pressurized water trying to leak out and rain and wind wont force as much thru the weave when used as line protection. But if it soaks up water like cloth then maybe that is enough.

Thanks! The best treatment of the subject I've come across.

You should also check into dyneema mooring pendants, very abrasion resistant and some are impregnated with Durocoat to make them even more abrasion resistant.

We bought half of a cow, full thick grain leather, for maybe $40. It should be sufficient material for literally decades of chafe. The thing was huge. Came out looking like this, and have spared our lines much wear and tear:



Some of our friends are into using leather but from my standpoint they're sacrificial as it is, we have a ton of material, and with our heavy sewing machine knocking them out takes a few minutes.
