USCG Exam PracticeTwin-screw vessel handling
Under 33 CFR §164.35, a vessel fitted with lateral thrust propellers must have which instrument readable from the centerline conning position, except when operating on the Great Lakes and their connecting and tributary waters?
- A. An indicator showing shaft RPM for each lateral thruster
- B. An indicator showing the pitch and operational mode of the lateral thrusters
- ✓ An indicator showing the direction and amount of thrust of such propellersCorrect
- D. An indicator showing the vessel speeds at which the lateral thrusters are effective
Why C is correct
33 CFR §164.35(n) requires that vessels fitted with lateral thrust propellers have an indicator readable from the centerline conning position showing the direction and amount of thrust of such propellers. The speed-effectiveness table is a separate maneuvering fact sheet requirement under §164.35(g)(5).
