🔍 Key Concepts

• Standard anchor chain shot markings used in commercial practice • Relationship between shot number (15, 30, 45 fathoms, etc.) and the number of white links on each side of the detachable link • The color sequence of detachable links for 15, 30, 45 fathoms (red, white, blue)

💭 Think About

• How many shots is 30 fathoms, if one shot is 15 fathoms? Once you know the shot number, how does that relate to how many white links are painted on each side? • Look at which answer choices match the rule: 'number of white links on each side equals the shot number.' Which options can you eliminate based on that? • Which color is normally associated with the detachable link at 30 fathoms in the red–white–blue sequence? Use that to check which descriptions are incomplete or incorrect.

✅ Before You Answer

• Confirm that 1 shot = 15 fathoms and therefore 30 fathoms is the second shot • Verify the general rule: shot #1 = 1 white link each side, shot #2 = 2 white links each side, shot #3 = 3 white links each side, etc. • Check whether the option you choose is consistent with both the correct number of white links and the standard color of the detachable link at 30 fathoms.
