Question 3519 Deck General

70% to pass

A link on an anchor chain should be replaced when wear or grinding of surface cracks has reduced the cross section area by _______________.

A 6%
B 4%
C 8%
D 10%
AI Explanation

The correct answer is D) 10%. According to the regulations for US Coast Guard Captain's License Examinations, a link on an anchor chain should be replaced when wear or grinding of the surface cracks has reduced the cross-section area by 10% or more. This is the threshold specified in the regulations to ensure the chain maintains sufficient strength and integrity for safe use. The other options are incorrect because they do not align with the regulatory requirement. Replacing a link at 6%, 4%, or 8% reduction in cross-section area would be either too conservative or not conservative enough compared to the 10% threshold established in the regulations.
