Water System Draining & Flushing

Water left in plumbing during freezing temperatures can cause catastrophic damage to pipes, fittings, and tanks. Our thorough approach ensures every drop is removed or protected.

• Complete draining of freshwater tanks, lines, and hot water heaters
• Watermaker preservation with manufacturer-recommended storage solution
• Shower sump and drain pump clearing
• Head and holding tank system flushing and draining
• Bilge pump testing and bilge area cleaning
• All low points opened and drained to prevent trapped water

Antifreeze Treatment

For systems that cannot be fully drained, we use non-toxic, marine-grade propylene glycol antifreeze to prevent freeze damage throughout the vessel.

• Engine raw water cooling circuit antifreeze fill
• Generator cooling system protection
• All plumbing traps, drains, and P-traps treated
• Air conditioning seawater loops protected
• Toilet and head system antifreeze treatment

Engine & Generator Preservation

Engines and generators require special attention during extended storage periods to prevent corrosion, fuel degradation, and seal drying.

• Oil and filter change to remove acidic contaminants before storage
• Fuel system treatment with stabilizer to prevent diesel bug growth
• Fuel tank topping off to minimize condensation
• Exhaust system moisture protection
• Battery maintenance: disconnect, charge, and condition
• Fogging spray application to cylinders for internal corrosion prevention
• Belt inspection and tensioning for spring readiness

Sail & Canvas Storage

Sails, biminis, and canvas covers are significant investments that benefit greatly from proper off-season care.

• Sail removal, inspection, and cataloguing of any damage
• Cleaning and drying before folded storage
• Bimini, dodger, and cockpit enclosure removal
• Canvas cleaning, waterproofing treatment, and dry storage
• Running rigging inspection and lubrication
• Furling system inspection and servicing

Winter Covers & Shrink Wrapping

A quality winter cover or professional shrink wrap protects your catamaran from snow, ice, rain, and UV damage throughout the storage period.

• Custom-fitted shrink wrap with support framework
• Ventilation openings to prevent moisture buildup and mold
• Access doors for periodic inspection visits
• Snow load consideration in framework design
• Reusable custom cover installation where preferred

Securing for Storage

Whether your catamaran is stored ashore or afloat, proper securing is critical for preventing damage from weather events and environmental factors.

• Cradle or jack stand inspection and adjustment
• Through-hull valve inspection and closure
• Rudder and drive leg protection
• Bottom cleaning and antifouling assessment

• Dock line inspection and chafe protection
• Fender placement and securing
• Seacock management and monitoring plan
• Bilge pump and float switch testing
• Shore power connection verification
