Lifejackets, harnesses and lifelines

A lifejacket supports flotation; harness and boat connection address restraint. One product can combine those functions without making them identical. Geometry matters too: connection length, path and attachment location influence whether a person can fall outside. “Attached” means neither “unable to fall” nor “protected from dragging”. Understanding the distinction is essential before trying an in-service connection.

This chapter introduces the subject and bounded exercises. It replaces neither training, equipment instructions nor applicable requirements.
