Bowline: mooring pin, ring
The canalman’s hitch works best on a bollard. If you’re attaching a line from the boat to a mooring ring or mooring spike with an eye hole, the bowline (pronounced BO-lin) knot is preferred. It won’t slip and can be easily untied if there is no load on the line.
Step 1
Make a loop and pass the end of the line through it.
Step 2, 3
Pass the end of the line around the back of the line from the boat
Step 4
Pass the back of the line back through the loop you created in step 1.
