Bulkhead

A bulkhead is a vertical structural partition inside a boat or ship, usually built into the hull, deck structure, or accommodation. Bulkheads divide the vessel into compartments and may be watertight, fire-resistant, or load-bearing, helping the boat retain strength and integrity at sea.

For boaters, bulkheads are critical to safety and seaworthiness. A watertight bulkhead can slow or contain flooding after a collision, grounding, or failed fitting, protecting buoyancy and giving crew time to respond. Their condition is closely linked to the Hull, the Bilge, and access to a Bilge Pump.

Common examples include collision bulkheads near the bow, engine-room bulkheads, and structural partitions around cabins or lockers. Any equipment, plumbing, or wiring passing through a bulkhead should be properly sealed; a poorly finished Cable Run can compromise watertight integrity. In heavy weather, sound bulkheads help the vessel withstand slamming, torsion, and repeated sea loads.
