In small passenger vessel regulations, an "open boat" is defined as a vessel that is not protected from entry of water by a complete weather tight deck.

• A. That is not protected from entry of water by means of complete weather tight deck
• B. A vessel with an enclosed cabin and no lifeboats
• C. A vessel with a weather-tight deck
• D. A vessel restricted to near-shore operations

Answer: (A)

The concept being tested is how an “open boat” is defined in relation to water protection from the deck. An open boat is one that does not have a complete weather-tight deck blocking water from entering the vessel. If there isn’t a fully weather-tight deck, water can enter, so the vessel is considered open.

That’s why the correct description is the one stating it is not protected from entry of water by a complete weather-tight deck. The other ideas don’t define open versus closed in terms of deck watertight integrity: having an enclosed cabin with no lifeboats, or having a weather-tight deck, or being limited to near-shore operations, do not establish the open-boat classification.
