INTERNATIONAL ONLY Which statement is TRUE concerning a vessel "constrained by her draft"?

Correct Answer: Option B — She must be a power-driven vessel.

Rule 3(h) explicitly defines a vessel constrained by her draft as a power-driven vessel. Unlike vessels restricted in their ability to maneuver or not under command, this status is strictly limited to power-driven vessels experiencing physical depth limitations, excluding sailing vessels or those being towed from this specific designation.
