Maritime QuestionsLoadline Marks Freeboard

Your examiner asks: "What is the Record of Draughts and Freeboards, and what entries does it contain?"

A. It is a record (often within the stability information or as a standalone log) of the vessel's draughts and corresponding actual freeboards at departure/arrival or other relevant points, used to verify the vessel was not loaded beyond its permitted load line for the applicable zone/season and density at the time, and to cross-check against the deadweight scale/hydrostatic data — examiners commonly walk through specific columns of this record and ask the candidate to explain what each represents.
B. The Record of Draughts and Freeboards is a class society survey-only document with no entries made by ship's staff.
C. This record applies only to passenger ships and has no equivalent requirement for cargo vessels.
D. The record contains only fuel consumption figures, unrelated to draught or freeboard.

Your examiner places a model ship in front of you and asks: "As a load line surveyor, where would you expect to find this vessel's load lines?"
A. The load line marks (the Plimsoll disc and the associated lines for summer/winter/tropical/fresh water etc.) are positioned amidships on each side of the ship, at the load line deck line reference, generally at about the mid-draught area of the ship's side — exact positioning and whether alternative load lines are assigned (e.g. for combination passenger/vehicle carriage) depends on the ship type and its conditions of assignment.
B. Load lines are always painted on the bow only, never amidships, regardless of ship type.
C. Only oil tankers are required to carry load line marks; all other ship types are exempt from load line marking.
D. Load line marks are applied solely to the stern of the vessel, next to the draught marks, with no amidships marking required.

Your examiner asks: "What is Dock Water Allowance (DWA), and how do you calculate it?"
A. DWA is the additional permissible immersion (beyond the assigned salt-water load line) allowed when loading in water of density less than standard seawater (1.025), since the ship will ride deeper for the same displacement in less dense water — it is calculated from the difference between the dock water density and 1.025, combined with the Fresh Water Allowance (FWA, the allowance for loading in completely fresh water, found on the load line certificate/stability information), proportioned for the actual dock water density measured with a hydrometer.
B. DWA is a fixed allowance of 50mm applied identically regardless of actual dock water density.
C. DWA applies only when departing port, not when loading, and has no relationship to the FWA figure.
D. DWA is calculated from the ship's deadweight scale alone, with no reference to water density at all.
