76. Mooring Hitch

Also known as: High Post Hitch

This hitch is used to tie a boat to a bollard, tree, or post on a shoreline high
above the water, especially useful in locks and areas of wide tidal change. If
the working end is left long, the knot can be instantly released from the
deck. When released, the rope remains around the bollard, until you release
the working end and pull it all the way off.

Uses: quick-release adjustable hitch for constant light loads
Pros: releases instantly and adjustable far from the fixed object

Cons: rather insecure
