I'm never around sand, but sand is one of those terrains where kinetic rope is useful. I used to watch a lot of Matt's Offroad Recovery on YT before that channel went to crap and all the fun personalities left.....but you'd see them do a lot of sand recoveries where you just had to get a running start and yank. Going down the YT recovery rabbit hole can turn up a lot of good stuff. The aussies always have great videos too. It's good to see as many different techniques and generally how vehicles react in different situations.

 

Resharp I had to edit my post as I wrote turnbuckle when I actually meant snatchblock. Must have been drinking when I wrote the reply.

 

or you're on a boat sailing , I figured it was a lapsus

 

Kinetic ropes/straps are needed when you are in areas with little or no traction and you don't have anywhere to connect a winch line to. Kinetics should be matched to the weight of the vehicle. Some are heavier than others. Kinetics store a lot of energy when stretched & if a connection point breaks, then bad things happen quickly. Heavy objects can become fast moving projectiles. I prefer not to use kinetics if other options exist.

Low stretch straps and certain types of low stretch synthetic ropes store less energy & are therefore less hazardous to use in pulling applications. Dynema is one brand name of UHMWPE rope that is very strong & very low stretch. 1/4" has a break strength somewhere around 8 or 10 thousand pounds. This is the same material that soft shackles are made from & the same material that synthetic winch ropes are made from. Low stretch ropes should not be used in dynamic pull situations. Do not get a running start with them. Apply tension gradually. You might be surprised what hardware will break when you jerk on a piece of 1/2" Dynema too hard.

Not all synthetic ropes are low stretch. Nylon is very stretchy.

It is considered best practice to hang a few jackets or towels over a winch line that is being used near it's limits so that in the event that it does break, there is something to slow it down a little bit when it's pieces go flying.

Wide straps are preferred for wrapping around trees. Dynema will cut into a tree & damage it badly. I've had 80# Dynema fishing line cut through the fiberglass gunwale of a boat when a large fish took off in a hurry. That stuff can cut through things better than you might expect.

Dynema does not like a tight bend radius. If you wrap it around something much less than 1.5 or 2 times it's diameter, then it's strength will be decreased significantly. Don't wrap it around a sharp corner.

Your system is as strong as it's weakest link. Know the load ratings of all components that you use, including the recovery points on your jeep that you attach the gear to.

 

spend the money and get a YellowTop battery. I had a boatload of issues with my 2011 JKU. Too many issues to list. Eventually I got the stealership to bench test the battery. It was a weird situation short version, new battery in order. They will NOT put anything different in so I got my own YellowTop solved ALL of my issues and still going strong a couple of years later. The stealership mechanic told me that my Jeep needed a better battery than it was shipped with and it comes up as an issue often. Battery is too important with all the electrics these days to cheap out on
