Where do you get this? I've seen all-polypro rope, and Spectra with
polypro braided exterior, but not Dynema. Only 2 hits on the web for
"polypro Dynema rope", neither with substantial information.

WARNING: Boatnerd talk ahead - lubbers please avert your eyes.

I've been using Samson Ultralight, which is Polypro/Dynema SK-60 and
Yale Conception which is Polypro/Dynema SK-75. Conception is single
braid which means you can splice it, so I've been using it for
split-tail mainsheets. Ultralight is a Dynema core under a polypro
cover which makes it a PITA to splice, but it works well for anything
that doesn't need splicing. There are other choices as well.

You can get them from the usual suppliers, like APS.

Plus they work great as thongs and string bikinis for spring [ob]skiing.

LOL. Thanks for the info Walt!

For whitewater boaters, looks like Yale Conception would make a great
throw-rope, while Samson Lite Speed would make a great rescue line.

Both are lighter than Spectra rope, and stronger than polypro rope.
The Samson Lite Speed actually has higher tensile strength than Spectra
of the same diameter.


I'm not a whitewater boater, so take what I say with the right degree of
skepticism, but I would think that for a rescue line you want a bit of
stretch. For instance, climbing ropes always have a bit of stretch
(made out of nylon usually). The Yale and Samson lines in question are
intended for use as halyards, sheets, and control lines on a sailboat
and are intentionally made to have as little stretch as is possible.
I'm not sure that ultra low stretch is what you want in a throw line.

For my throwable lines, I just use garden variety 3/8 inch 25 cents a
foot polypro - I don't see the need for ultra low stretch or ultra high
strength in a throwable. And for docklines, you really don't want low
stretch - I've seen boats with damaged hulls because the owner recycled
his old sheets as docklines. Let the line absorb the shock, not the boat.

For [ob]skiing the only lines I ever use is yarn for powder cords.
