USCG Exam PracticeSingle-screw maneuvering and prop walk
According to 33 CFR §164.35(g), the maneuvering information fact sheet required to be prominently displayed in the wheelhouse must state the conditions upon which the data is based. Which of the following is one of those baseline conditions?
- A. Water depth equal to the vessel's draft
- B. Wind speed of 15 knots or less
- ✓ Water depth twice the vessel's draft or greaterCorrect
- D. Current not exceeding 0.5 knots
Why C is correct
33 CFR §164.35(g)(6)(iii) specifies that the maneuvering information is based on deep water conditions defined as water depth twice the vessel's draft or greater. The warning statement at the bottom of the fact sheet also lists this same condition. Wind speed of 10 knots or less—not 15—is the correct wind baseline per §164.35(g)(6)(i).
