INTERNATIONAL ONLY Which vessel is NOT regarded as being "restricted in her ability to maneuver"?

A A vessel constrained by her draft
B A towing vessel with tow unable to deviate from its course
C A vessel engaged in dredging
D A vessel servicing an aid to navigation
AI Explanation

The correct answer is A) A vessel constrained by her draft. A vessel constrained by her draft is not regarded as being "restricted in her ability to maneuver" under the International Regulations for Preventing Collisions at Sea (COLREGS). This is because a vessel constrained by her draft is not limited in her ability to change course or speed, even though her draft may restrict the waters she can safely navigate. The other options (B, C, and D) describe vessels that are considered "restricted in their ability to maneuver" and must follow the corresponding rules under the COLREGS.
