🔍 Key Concepts

• Bulwark functions on the weather deck • Purpose of openings that let shipped seas and rainwater drain overboard • Difference between openings for ventilation, access, and drainage

💭 Think About

• Think about which fittings are specifically designed to let water on deck escape quickly in heavy weather. • Ask yourself which of these terms you usually hear in connection with bulwarks and safety against deck flooding, not machinery or closures. • Consider which openings must be sized and positioned according to stability and seaworthiness rules to prevent water accumulation on deck.

✅ Before You Answer

• Match the term to drainage of deck water through the bulwark. • Eliminate any option you associate with ventilation trunks, access openings, or fasteners/closures rather than drainage. • Recall that SOLAS and load line rules specify minimum area for these drainage openings along the weather deck bulwarks.
