Question 2

Two half hitches

Answer

Two half hitches form a reliable hitch around a ring or rail and are a standard seamanship fastening.

Answer

Nylon stretches significantly under load, acting as a shock absorber that reduces peak stress on deck fittings and anchors.

Question 5

Which knot is known as the 'king of knots' for forming a secure, non-slipping loop at the end of a line?

Accepted Answer

Bowline

Answer

The bowline creates a fixed loop that will not slip or jam and can be untied easily, making it one of the most important knots in seamanship.
