Question 3420 Deck General

The correct answer is A) go-no-go gauge. A go-no-go gauge is a specialized measurement tool used to inspect anchor chain links and ensure they meet the required size and integrity standards. It allows inspectors to quickly and accurately determine if the chain links fall within the acceptable dimensional tolerances, which is an important safety check for the vessel's mooring and anchoring system. The other answer choices are incorrect because: B) an amp probe is used to measure electrical current, C) a slide rule is a manual calculation device, and D) a derrick tape is used to measure the height of the vessel's derrick, not the anchor chain.
