I have 300' of that BlueWater II Plus in 1/2". Quality stuff. I like it. I also take along 300' of BlueWater's BW-HR3 River Rescue Rope in 1/2". The BW-HR3 floats. BW II + doesn't. Just so you know.
We used the BW II + extensively in the SWR Class I took. It worked quite well.
300' is a lot of rope in this diameter. I have them both in a Butterfly Coil and it's damn near four feet long folded in half and roughly ten to eleven inches in diameter, roughly. The web site has the weight of course.
It's a pretty extensive Pin Kit but I have the real estate for it...
Because I have a "Pig Rig".
