Question 2069 Deck General

The correct answer is D) be of the same length. To double the strength of a mooring line, the second line must be of the same length as the first line. This is because the two lines need to share the load equally in order to double the strength. If the lines are not the same length, the longer line will take on more of the load, preventing an even distribution and limiting the increase in strength. The other options are incorrect because: A) crossing the lines is not necessary, B) "marrying" the lines (tying them together) is also not required, and C) the diameter of the second line does not need to be 1 1/2 times the first, as long as it is the same length.
