through-hull
Boat's plumbing portal
A through-hull is a fitting that passes through a boat's hull, allowing water to flow in or out for purposes like cooling engines, operating toilets, or draining sinks.
Through-hulls are potential failure points—if one fails below the waterline, the boat can sink.
Check all through-hulls before launching.
Also used as an adjective: through-hull fitting, through-hull valve.
