Cal Poly Maritime – Marlinspike (DL 1115) Practice Test

When you need to join two lines or large hawsers for towing, you want a knot that binds firmly, distributes the load evenly, and stays secure under heavy pulling while remaining easy to untie later. The Carrick bend does exactly that with its interlocking, symmetrical turns that grip both lines and resist slipping under tension. It’s particularly reliable for joining lines of different diameters and for towing where the stress is high.

Two half hitches are made to secure a rope to a post or another rope, not to join two separate lines. A bowline creates a fixed loop at the end of a line, which isn’t suited for linking two lines together. The becket bend can join two lines but isn’t as dependable under heavy towing loads and can be harder to untie after being heavily loaded. So the Carrick bend is the best choice for towing two lines or large hawsers.
