Project Farm tests kinetic ropes

That didn't make me reconsider my Sgt Knots rope. Performance wasnt that far off the best and, for the price, it can be replaced several times for the cost of the popular brand names.

That was kind of my thought too - as much as I'll probably (not) need the thing, but its nice to have JIC.

Our cruise ship was docking in Alaska. The dock hand had a front dock line attached to a large forklift. As he was pulling it snapped and the end, about 12’, landed on the dock at the back of the ship. The sound was amazing.

I may just have to order one myself.

That sound will make you crap your pants. I remember a destroyer tender popping a couple of lines on the pier in Sicily. Fuck off, no thanks for any line parting, on a ship or on your Jeep.

ditto. anyone got the tldw summary?

Typical PF stuff. If you aren't knowledgeable and aware of what's going on, the results look like he knows what he is doing. If you are aware, you come away wondering how he didn't wind up with the drawbar going through the back window of his tow rig. I would have never done that test without a piece of 1/4" steel plate blocking the whole rear of the vehicle. I don't know who convinced him that he was able to pull of the Busteresque copy of the Mythbusters test dummy but they shouldn't have. It isn't cute, entertaining or additive to anything of value.

The testing protocol is reasonably flawed since there is not an accellerometer on the tow rig to get a complete picture of mass x velocity and wind up with the force on each test. He is simply depending on how consistently he can stomp on the throttle and hit the end of the ropes. 7000 lbs hitting a rope at 25 mph is not the same force as hitting it at 28 mph and that difference will produce different results.

A wire rope parted out at sea - the backlash instantly decapitated a crewman. When it goes to shit, it goes FAST! It was QUITE the subject of discussion at our safety meetings (and elsewhere!).

PF's testing protocol isn't highly scientific even though he tries to quantify things that you sometimes wonder why bother. I was impressed with how hard (IMO) he used the ropes and apparently none broke. It looks like an inexpensive rope might be good enough for guys who have no intention of needing one but have it just in case or to help someone else.

Do these have a shelf life not considering damage from use?

He wasn't using them very hard. I've used them with double the slack, slamming the throttle on my 1 ton dually, and then hitting the end of a 1 1/8" version to unstick a propane delivery truck. I had to hit it about 10 times like that to get him moving but it did it.

OK not that hard but what he did should unstick a Wrangler shouldn't it?

"Unstick a Wrangler" is pretty vague. In a couple inches of sand? Probably. Up to your doors in thick mud? Probably not.
