Owning a boat in Sea Isle on Galveston Island means year-round coastal fun—but winter still brings cooler temperatures, salt-heavy humidity, and long periods of disuse. Proper winterizing prevents costly repairs, protects your boat’s systems, and ensures your vessel is ready for smooth launching when spring arrives. Here are expert tips to protect your boat this winter.

1. Flush & Stabilize the Engine

Saltwater and winter downtime are a bad combination for engines. To prevent corrosion and fuel breakdown:

Flush the engine thoroughly with fresh water
Add a marine fuel stabilizer
Run the engine briefly to circulate treated fuel
Change engine oil and replace filters

This keeps your engine lubricated and prevents internal rusting during storage.

2. Clean & Dry the Entire Vessel

Moisture and salt residue can damage every part of your boat. Before storing:

Wash the hull, deck, and interior surfaces
Remove salt buildup from metal hardware
Vacuum carpets and wipe upholstery
Allow everything to fully air-dry

A clean boat is far less likely to develop mold or corrosion over winter.

3. Protect Electronics & Batteries

Electronics are especially vulnerable to winter moisture. Best practices include:

Disconnect and remove batteries
Store batteries in a climate-controlled location
Remove GPS units, radios, and depth finders
Store them in padded, secure containers

This extends the lifespan of costly equipment.

4. Cover & Ventilate Properly

A good cover protects your boat from winter sun, salt air, and moisture—but it must be breathable. Use:

A marine-grade vented cover
Moisture-absorbing products inside cabins
Support poles to prevent water pooling

Proper airflow prevents mildew and interior damage.

5. Store Your Boat on Elevated, Secure Surfaces

Whether you use trailer storage, covered storage, or a drive-up unit, ensure your boat is:

Stored on an elevated, paved surface
Secured with wheel chocks
Positioned away from standing water
Protected from wind-blown debris

For Sea Isle residents, off-site storage offers extra protection from storms and coastal moisture.
