USCG Exam PracticeSingle-screw maneuvering and prop walk
Under 33 CFR §164.35, the maneuvering information fact sheet required to be prominently displayed in the wheelhouse must state the baseline conditions under which the data was derived. Which of the following correctly identifies those baseline conditions?
- A. Wind 15 knots or less, no current, water depth equal to the vessel's draft, and clean hull
- ✓ Calm weather with wind 10 knots or less, no current, water depth twice the vessel's draft or greater, and clean hullCorrect
- C. Calm weather with wind 10 knots or less, current not exceeding 0.5 knots, deep water, and clean hull
- D. No wind, no current, water depth twice the vessel's draft or greater, and normal load condition only
Why B is correct
33 CFR §164.35(g)(6) and the warning statement at the bottom of the fact sheet specify four baseline conditions: calm weather with wind 10 knots or less and calm sea; no current; deep water conditions defined as water depth twice the vessel's draft or greater; and clean hull. Any variation from these conditions may alter the vessel's response.
