Question 4090 Deck General

70% to pass

You are arriving in port and are assigned to anchor in anchorage circle B-4. It has a diameter of 600 yards and your vessel's LOA is 525 feet. If you anchor in 10 fathoms at the center of the circle, what is the maximum number of shots of chain you can use and still remain in the circle?

A 4 shots
B 5 shots
C 6 shots
D 7 shots
AI Explanation

The correct answer is A) 4 shots. The reasoning behind this is as follows: 1) The diameter of the anchorage circle B-4 is 600 yards, which is equivalent to 1,800 feet. 2) The vessel's length overall (LOA) is 525 feet. 3) According to standard practice, the scope of chain (length of chain paid out) should be 5 to 7 times the depth of the water, which is 10 fathoms or 60 feet. 4) Using a scope of 5 times the depth, the maximum length of chain that can be used and still remain within the 1,800-foot diameter circle is 4 shots (each shot being 90 feet), as this would result in a total scope of 360 feet, which is well within the circle's diameter. The other options are incorrect because using 5, 6, or 7 shots of chain would result in the vessel exceeding the boundaries of the anchorage circle.
