USCG Exam Practice · Single-screw maneuvering and prop walk
Under 33 CFR §164.35(g), the wheelhouse maneuvering fact sheet for a vessel fitted with a fixed propeller must include which of the following in addition to turning circle and stopping distance data?
- AA table of shaft revolutions per minute for a representative range of speeds✓ correct
- BA table of control settings for a representative range of propeller pitch settings
- CA table of vessel speeds at which the bow thruster becomes effective
- DA table of rudder angles required to maintain course at each listed speed
Why A is correct
33 CFR §164.35(g)(3) requires that for each vessel with a fixed propeller, the fact sheet include a table of shaft revolutions per minute for a representative range of speeds. A table of control settings for a representative range of speeds is required under §164.35(g)(4) for controllable pitch propellers, not fixed propellers. The bow thruster table under §164.35(g)(5) applies only to vessels fitted with such auxiliary devices.
