USCG Exam PracticeTwin-screw vessel handling
A vessel fitted with a bow thruster is required by 33 CFR §164.35 to include which specific information about that device on the wheelhouse maneuvering fact sheet?
- A. The maximum thrust output in kilonewtons at full power
- ✓ A table of vessel speeds at which the bow thruster is effective in maneuvering the vesselCorrect
- C. The turning circle diameter achievable using the bow thruster alone at slow speed
- D. The time required to shift the bow thruster from full port to full starboard thrust
Why B is correct
33 CFR §164.35(g)(5) requires that for each vessel fitted with an auxiliary device to assist in maneuvering, such as a bow thruster, the fact sheet include a table of vessel speeds at which the auxiliary device is effective in maneuvering the vessel. Thrust output values, turning circles using the thruster alone, and shift times are not specified requirements.
