Short Tows

I see many people with short tows attached to their decks, usually just some line with a carabiner at each end. Some use them exclusively as a paddle park and others use them with contact tows or while rafting up. It recently dawned on me that without a quick release these could easily become a hazard, so I have taken to removing one of the carabiners and substituting it with a slip hitch to my deck line. The knot I use is a mooring hitch and while it easily releases with one hand, it binds well under pressure.

Knots - Mooring Hitch

An underhand loop toggled to the standing part with a bight made in the running end To securely tie off a rope so that it can be quickly untied, especially a small boat to a dock or piling. A secure knot that is easily tied or untied in wet or dry rope; when properly tied a non closing loop is formed, this allows the hitch to move up or down a piling as the water level changes. (1) Take a bight around an object. (2) Form an underhand loop in the running part. (3) Place the eye of the underhand loop over the standing part. (4) Pull a bight of the standing part through the eye of the underhand loop. (5) Pull the underhand loop tight around the bight. (6) Place the running part under the eye of the bight that was pulled through the underhand loop. (7) Pull a bight of the running part through the eye of the standing part bight. (8) Pull on the standing part to tighten the standing part bight around the running part bight.
