Nautical Terms

• Distinguish the vessel's ends from directions of movement and use bow, stern, fore, aft and amidships correctly in a crew instruction.
• Identify the vessel's port and starboard sides from any position aboard and relate them to navigation sidelights without confusing buoyage regions.
• Explain hull, waterline, draught, freeboard, keel and rudder, and identify which measurement constrains entry into shallow water.
