The interior of a boat is compartmentalized into bulkheads, decks, and hatches. The hatches are doors; when closed, the space between them becomes watertight and is called.

• A. WATERTIGHT COMPARTMENT
• B. WATERTIGHT CHAMBER
• C. WATERTIGHT ENCLOSURE
• D. WATERTIGHT SPHERE

Answer: (C)

When hatches are closed, the walls, deck, and the doors themselves create a sealed, bounded space inside the hull. That enclosed, watertight area is described as a watertight enclosure. The term emphasizes the space being sealed off by watertight boundaries to prevent water from flowing into adjacent areas, which is exactly what the closed hatches accomplish. While a watertight compartment conveys a similar idea, enclosure specifically highlights the bounded space formed between those doors. The other options are less precise for this context.
