USCG Exam PracticePlotting with variation and deviation (T-V-M-D-C)
Pre-voyage planning for a towing vessel operating seaward of the U.S. territorial sea baseline must include which of the following items?
- A. Calculated speed and estimated time of arrival at proposed waypoints only
- ✓ Forward and after drafts of the barge and under-keel and vertical clearances for all bridges, ports, and berthing areasCorrect
- C. A deviation card corrected for each waypoint along the route
- D. A written exemption from the Captain of the Port for each voyage
Why B is correct
33 CFR §164.80(c)(3)(iv) specifically requires the voyage plan to include forward and after drafts of the barge or barges and under-keel and vertical clearances (air-gaps) for all bridges, ports, and berthing areas. A deviation card is not listed as a voyage plan element, and a COTP exemption is not required for each voyage.
