Easy to handle and ready to use. The Shockline protects your boat, cleats and your dock from stress caused by wind, waves and wakes. The dock line is manufactured from high stretch braided polyester with a section of shock absorbing memory rubber woven in, providing the shock absorption needed while limiting the maximum stretch. With these dock lines you have an all-in-one system with integrated elongation zone. The dock lines have a hand spliced 12" eye, are braided and have excellent abrasion resistance.
