A 6 ft. Spectra® tow strap equipped with a locking carabiner. This system safely packs into the side pocket of our rescue vests, making it easily accessible but not dangerously hanging where it could get caught on logs and such.
I use this web toe (tow) in combination with my Astral Greenjacket! Paddling with newer paddlers, and even some seasoned paddlers, it has surely proven useful when needing to tow a boat to the nearest eddy/shore! Thanks Astral and Mountainman!
