The maneuvering information required to be posted in the wheelhouse must be based on certain conditions. Which of the following is NOT one of these conditions?

Correct Answer: Option D — The depth of the water must be at least one and one-half times the draft.

IMO and USCG requirements for maneuvering data (33 CFR 164.35) specify that trials must be conducted in deep water, defined as a depth at least four times the draft. A depth of one and one-half times the draft is insufficient and would cause significant shallow water effects, invalidating the data.
