Collision Mat Drill for Wooden-Hulled Vessels

This maritime drill checklist guides wooden-hulled liveaboard vessels through a full collision mat exercise to control flooding after a hull breach. It covers inboard actions to investigate and stabilize the vessel, and outboard actions performed by dive teams to position and secure a collision mat. The template prompts alarm and communications, notifying authorities, headcounts, pump activation, and rapid damage assessment. It details preparation of the mat, line handling, diver deployment, securing cables and D-clamps, verification of watertightness, and continuous monitoring. Station bill roles for captain, engineers, mates, deck crew, and dive crew are reviewed, followed by debrief, scoring, corrective actions, and logging to keep the emergency plan current.
