Step-by-step instructions
Identify moisture sources
Look for leaks, wet sails, shower condensation and poorly ventilated lockers.
Improve safe airflow
Use passive ventilation or controlled fans without blocking combustion-air or electrical cooling requirements.
Separate vulnerable gear
Store tools and spares off damp hull surfaces and use suitable sealed containers where needed.
Inspect regularly
Check accessible hardware for rust and electrical areas for moisture without opening live equipment.
Address leaks quickly
Dry affected spaces and fix the actual entry point before applying corrosion products.
Safety note
Do not spray chemicals onto energized circuits or use unventilated combustion heaters to dry cabins.
Key takeaway
Corrosion control begins with stopping persistent moisture.
