Question 4719Deck General70% to pass
The DEEP DRILLER, at a mean draft of 45 feet, has a three-foot trim by the stern and a two-foot list to port. What is the draft at the starboard forward draft mark?
AI Explanation
The correct answer is A) 42.5 feet.
To calculate the draft at the starboard forward draft mark, we need to consider the mean draft, trim, and list of the vessel.
Given:
- Mean draft: 45 feet
- Trim by the stern: 3 feet
- List to port: 2 feet
The draft at the starboard forward draft mark would be the mean draft (45 feet) minus the trim by the stern (3 feet) and half the list to port (1 foot), which equals 42.5 feet.
The other options are incorrect because they do not properly account for the trim and list of the vessel.
