Question 2197 Deck Safety

70% to pass

The change in weight (measured in tons) which causes a draft change of one inch is _______________.

A MH1 inch
B ML1 inch
C MT1 inch
D TPI
AI Explanation

The correct answer is D) TPI. The term "TPI" stands for "Tons Per Inch" and is the measure of the change in weight (in tons) that causes a draft change of one inch. This is a fundamental concept in ship stability and is a key piece of information needed for Coast Guard Captain's License Examinations. The other options are incorrect because they do not represent the actual measure of the weight change per inch of draft. MH1 inch, ML1 inch, and MT1 inch are not standard units used to describe this relationship.
