Crew Member Chris Speers: 'The bowline creates a strong loop that can be used for lots of things. It’s one of the most commonly used knots on a lifeboat, and it’s mainly used for mooring and berthing.'

Step 1: Take your rope.

Step 2: Make a loop, so the working (tail) end is at the back of the loop.

Step 3: Flip that tail end toward you through the loop and over the top of the loop.

Step 4: Bring the tail end from right to left in between the standing (long) end and the loop.

Step 5: Bring the tail end back to the front of your knot and pass it through the large gap in the knot.

Step 6: Pull both ends to tighten.
