UHMWPE Core Polyester Cover Low Stretch Sailing Rope Choose Size/Length/Color

It's definitely UHMWPE core. It doesn't melt, it's slippery, and it's very strong. To test, I spliced an eye, put it on a cleat, and loaded the other end on a winch. Since that worked, I installed it as the tack line for my spinnaker. In the video, we're doing 16kts in 18-20kts of wind. The spinnaker is over 1000 sq ft (45m2). At the very least, we would have seen stretch in a polyester core rope and there was no stretch in this line. Splicing is about the same as any similar rope. A brummel splice without cover is easy; re-covering is hard. I chose the lazy route.

Spliced and handled well. Have only used the sheets twice, but working out fine.

Seems like good rope as long as you don't need to splice it. The polyester cover is very tightly woven and the UHMWPE core is uncoated and very loose. With something like Samson Warpspeed you can just strip the cover off and eye splice the coated 12-strand core like a regular single braid dyneema, but I really don't think that this rope should be used with its loose floppy core uncovered. It is probably easy enough to do a covered splice with the cover tail seized and whipped at the throat, but I prefer to bury the cover tail. I tried the technique in the Yale video of their high-performance double braid splice as it is generally good with loose core lines, but there was no way to get the core to bury. Usually, with a bit of hammering, flexing, winching, dish soap, etc, you can eventually get the full bury, but not on this stuff. This is the first rope that defeated me Finally, I stripped off a couple of meters of cover and replaced it with dyneema chafe sleeve and did the splice with that, and that worked perfectly. I followed the Premium Ropes strip and recover video. It all worked out for me because it was 200' of 12mm line, so the money saved over the equivalent line from New England or Samson or Marlow was considerable, maybe even enough to make the extra hassle of a more complex splice worth while. Maybe. I would suggest if you are a neophyte at splicing, don't start with this stuff, and if you are an expert, you'll succeed only by delving into your bag of tricks.

This was sent with a polyester core. Confirmed with both color and burn test. DON'T BUY

Nice Rope

This does appear to be UHMWPE based on the a burn and a float test of the core (there was some doubt), but spicing/burying the splice doesn't seem to work well.. the core doesn't want to hold the end of the spice into itself. I had to whip around the end of the splice area, which is odd, but I could live with that. Secondly, the cover is very slippery and it holds poorly on a non-self-tailing Lewmar 40 winch I use for primary genoa trim that has no issue with other lines I've used in the past. I would not recommend this line for regular use as a heavy-load running rigging line from my experience.

Upon receipt it looked like this product had a polyester core. However, burn and melt tests proved that it is definitely a UHMWPE core - UHMW-PE’s high molecular weight means it will not melt or flow as a molten liquid. The line is well made with very little compress-ability, unlike cheap double braid polyester line. Good seller feedback and great price.
