What is the least depth at Terminal 42 according to the specified regulations?

The least depth at Terminal 42, as per the specified regulations, is 45.0 feet. This value is typically determined by relevant maritime and navigational standards that ensure safe docking and berthing of vessels. Such depths are crucial for preventing grounding incidents and related hazards, especially for larger vessels with deeper drafts. Ensuring that the depth meets or exceeds this threshold allows for adequate clearance under various conditions, both during high and low tide.

Understanding maritime regulations often involves consulting local guidelines that establish minimum depth requirements to accommodate different classes of vessels while considering seasonal changes in water levels. The choice of 45.0 feet indicates a commitment to safety and operational efficiency, supporting the terminal's ability to handle vessels safely without interference from the seabed.

Other depth options, while representing plausible values, fail to meet the minimum established threshold specified by terminal regulations, which is why they are not categorized as appropriate answers.
