Question 3393 Deck General

70% to pass

Given the same water depth and mooring tension, the length of the ground cable of a 19 pound/foot wire rope mooring line in comparison to a 90 pound/foot mooring chain will be _______________.

A shorter
B longer
C identical
D indeterminable
AI Explanation

The correct answer is A) shorter. The length of the ground cable for a mooring line is inversely proportional to the weight (or density) of the mooring material. Since the wire rope has a lower weight per foot (19 lb/ft) compared to the mooring chain (90 lb/ft), the wire rope ground cable will be shorter than the mooring chain ground cable, given the same water depth and mooring tension. The other options are incorrect because: B) longer is the opposite of the correct answer, C) identical is not true since the weights per foot are different, and D) indeterminable is not correct since the relationship between the ground cable lengths can be determined based on the weight per foot of the mooring materials.
