Question 2035 Deck General

The correct answer is A) Polypropylene. Polypropylene has the lowest melting point among the line materials listed, making it the type of line that melts easiest. Polypropylene has a melting point around 320°F (160°C), while Dacron (polyester) is around 480°F (250°C), Nylon is around 420°F (215°C), and wire does not technically melt, but can become deformed or fail at high temperatures. The ease of melting is an important consideration for Coast Guard Captain's License Examinations, as it relates to the fire safety and integrity of different types of maritime lines and ropes.
