Captain Gerry demonstrates how to tie a Sheet Bend knot:

The Sheet Bend knot is recommended for joining two ropes of unequal size.

1. Form a loop in the thicker rope and hold it in one hand.

2. Pass the thinner piece of rope through the loop, then round the loop.

3. Take care to go round the short end first, then round the long end.

4. Finally, tuck the smaller rope back under itself to finish the Sheet Bend.
