WebFeb 15, 2024 · The mooring lines used in this study are composed primarily of polyester rope; to avoid abrasion, they were required to always remain taut such that no part of the line lies horizontally along the seafloor. Finally, the midpoint of each shared line was required to stay below 60-m depth at all times so as not to obstruct navigation. WebIf you don't have a slip, tie extra-long lines to pilings or cleats to allow for the surge, which could be 10 feet or more. Use anchors or long spring lines to keep the boat from striking the dock. (Illustration: Erick Stevens) Lines should also be a larger diameter to resist chafe and excessive stretching.
