USCG Exam PracticeTwin-screw vessel handling
Under 33 CFR §164.11, which of the following factors must the person directing movement of the vessel consider when setting vessel speed?
- A. The vessel's compass deviation and gyrocompass error
- ✓ The tendency of the vessel to squat and suffer impaired maneuverability when underkeel clearance is smallCorrect
- C. The date and time of the next required position fix
- D. The number of steering-gear power units in simultaneous operation
Why B is correct
33 CFR §164.11(p)(3) specifically lists the tendency of the vessel underway to squat and suffer impairment of maneuverability when there is small underkeel clearance as a factor the conning officer must consider when setting speed. Compass errors and steering gear power units are separate requirements under §164.11(i) and §164.11(t) respectively and are not speed-setting considerations.
