Penetrations and openings in watertight bulkheads in a vessel of less than 100 gross tons must __________.

🔍 Key Concepts

• Watertight integrity and how openings affect flooding risk • The goal of watertight bulkheads on small vessels (less than 100 gross tons) • General principles for locating any required openings in watertight structures

💭 Think About

• If water gets into a compartment, how does the location of an opening (low vs. high, outboard vs. inboard) affect the spread of flooding? • Look at each choice: which ones describe design features that would actually weaken watertightness instead of preserving it? • Which option describes a general placement rule rather than a specialized fitting or unusual requirement?

✅ Before You Answer

• Identify which choice best supports limiting progressive flooding if the hull is damaged near the waterline • Eliminate any options that introduce extra potential leak paths (e.g., joints, valves) instead of minimizing them • Focus on the option that reflects a conservative placement of openings relative to the shell and the waterline
