What characterizes a stand-on vessel?

• A. A vessel that always yields
• B. A vessel that maintains its course and speed unless the give-way vessel isn't taking appropriate action
• C. A vessel that can change course arbitrarily
• D. A vessel that must stop

Answer: (B)

Stand-on vessels keep their current course and speed to stay predictable for other boats. The other boat, the give-way vessel, is the one that must take early and substantial action to avoid a collision. So the stand-on vessel does not automatically turn or stop; it maintains course and speed unless the other vessel isn’t taking appropriate action and the risk of collision continues, in which case the stand-on may take evasive action. This helps prevent sudden, confusing maneuvers and keeps traffic flowing safely.
