Which of the devices listed will prevent an inflated liferaft from being pulled under by a vessel which sinks in water over 100 feet deep?

Correct Answer: Option D — A weak link in the painter

A weak link in the sea painter is designed to fracture under specific tension loads (typically between 200 and 536 pounds depending on capacity). This prevents a sinking vessel from dragging an inflated liferaft down into deep water as the ship goes under.
