Dyneema as stainless rope replacement on davit

[oceanjake]

Has anyone here done this? Is there any concern about weather exposure or rot for the exposed braid ? What is the best connection for the davit hook and winch drum?I need to replace my wire rope and I like the idea of braid. It will be quieter, especially as it jumps over itself on the drum. I hate that sound. Thanks for the info.

I use it on my davit and it is wonderful. It is supposed to be UV protected, but we had some on our sailboat fail in the South Pacific from long sun exposure so I keep my davit covered just in case. We spliced on the hook and I used line with about the same diameter as the old wire so it attached to the drum in the same slot as the old wire and I leave quite a few wraps on the drum at all times. If you get the larger diameter to fit the drum slot you end up with line so strong you can probably lift the mothership with it but the larger diameter is not a lot more in price than the smaller.

How do you secure it to the drum? Most have a hole and set screw that clamps the cable

Just a heads up on the "quite a few wraps" comment: Due to leverage every wrap around the drum will reduce the lifting power. I only have one more wrap than I need.

We recently repacked the SS with Dynema on the Nautical Structure David on the boat I run. Much better it s an hydraulic David though so the line is always inside the unit. Dyneema should be reasonably UV resistant but I would use a cover on the winch anyway

The power davit I bought through the for sale section here was rebuilt for the previous owner by MarQuipt with Dyneema cabling for the hydraulic hoist. We’ve used it for a year now with no complaints. It’s nice to be able to grab the cable barehanded without worrying about getting hooked! There is about a six inch section that is not inside the boom when stowed, I ll need to keep an eye on it and be prepared to shorten it if needed.

I have Amsteel on mine. Looks like this is similar stuff.

[Photolomy]

Where are you guys sourcing the rope from? And what diameter are you using?

[SKYCHENEY]

Fisheries Supply has it. I used 1/4" and it looks like Amsteel is just a brand name. Same stuff. https://www.fisheriessupply.com/sams...SAAEgIpTPD_BwE

If you want it with loop already installed, look on Amazon:

We have used it for the past 8 years on our crane. Wonderful stuff, easy on the hands and very strong. Our which came with 1/4" wire rope. I switched it out almost immediately for Dyneema 5/16". It is east to splice a loop in the end, Youtube it.
