Question 1 of 2066636ee728f7522a1c517516

You are arriving in port and are assigned to anchor in anchorage circle B-4. It has a diameter of 500 yards and your vessel's LOA is 484 feet. If you anchor in 8 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?

🔍 Key Concepts

• Relationship between radius and diameter of the anchorage circle • Converting vessel length (feet) and scope of chain (fathoms/shots) into the same units (yards or feet) • How to calculate the swing circle radius = vessel length + length of chain

💭 Think About

• First, convert the anchorage circle diameter to a radius, and get that value in feet so it matches the vessel’s LOA units. What is the radius in feet? • Express one shot of chain in feet, then in fathoms if needed. How many feet of chain are in each shot? • For each choice, compute the total distance from the anchor to the stern: vessel LOA + length of chain. Which options keep this total less than or equal to the anchorage radius?

✅ Before You Answer

• Be sure you use radius, not diameter when comparing swing circle distance to the anchorage size. • Use the correct value for 1 shot of chain in feet, and then relate that to fathoms if needed. • Confirm that the final swing circle (LOA + chain length) does not exceed the radius of 250 yards (in feet).
