🔍 Key Concepts

• 46 CFR Subchapter T requirements for port lights and windows on small passenger vessels • Difference between weathertight and watertight openings below the weather deck • Flooding risk when a port light is located below the deepest load waterline on exposed or partially protected waters

💭 Think About

• Ask yourself: if a wave hits the side of the hull or the vessel heels over, which option best protects against water getting inside through that port light? • Consider whether the regulations are more concerned with how high the port is above the water, whether it opens, or whether it can be effectively sealed in heavy weather. • Think about why the rules treat port lights below the weather deck more strictly than cabin windows above the weather deck.

✅ Before You Answer

• Verify in 46 CFR Subchapter T that port lights below the weather deck on exposed/partially protected waters must have the highest level of integrity against flooding. • Check whether the rule emphasizes fixed (non-opening) construction, or the presence of a solid internal cover (deadlight), or just a minimum sill height above the waterline. • Confirm whether material alone (like plastic thickness) is ever listed as a primary condition for allowing a below‑deck port light in these waters.
