Question 2522 Deck General

You are correct, the answer is A) floats. Polypropylene is a synthetic fiber that is less dense than water, allowing it to float on the surface. This makes it an ideal choice for a messenger line when reconnecting a broken tow line, as the floating line is easier to grab and maneuver in the water compared to a sinking line. The other options are not the primary reasons for using polypropylene. While it does have good shock-absorbing stretch and tensile strength, the floating ability is the key advantage over other materials when dealing with a broken tow line at sea.
