Step-by-step instructions
Identify likely seawater ingress points
Mark seacocks, shaft seals, engine intake hoses, through-hulls and deck penetrations.
Review pumps and alarms
Verify access to automatic and manual pumps, discharge paths and high-water alarms.
Stock damage-control supplies
Keep appropriately sized plugs, soft patching materials and a safe light where crew can reach them.
Agree on emergency roles
Designate someone to control the boat, investigate only when safe, and call for help early.
Practice the response
Run a dry drill identifying fittings and communications without deliberately introducing water.
Safety note
Uncontrolled rising seawater is an emergency. Prioritize crew safety and distress communication; never enter a dangerous flooded compartment.
Key takeaway
Fast response depends on knowing where to look and who will do what before the leak starts.
