What are the steps to store a boat for the summer if I won't use it?

Preparing Your Boat for Summer Storage

Storing your boat correctly during the summer months is crucial for protecting your investment and ensuring it's ready for use when the season returns. Unlike winterization, which focuses on freezing temperatures, summer storage guards against heat, UV exposure, humidity, and prolonged inactivity. Following a systematic process will prevent costly damage from mold, mildew, fuel degradation, and mechanical issues.

Step 1: Thorough Cleaning and Inspection

Begin with a comprehensive wash using fresh water and boat-safe soap, removing all salt, dirt, and organic material. Clean the interior, including lockers and bilges, to prevent mildew. Once dry, conduct a detailed inspection of the hull, deck, and systems. Look for cracks, blisters, or any signs of wear that should be addressed before storage. A clean, dry boat is your first defense against deterioration.

Step 2: Engine and Mechanical System Preparation

Properly stabilizing the fuel system is critical. Industry findings indicate that ethanol-blended fuel can separate and cause issues in as little as 30 days. Add a high-quality fuel stabilizer to a nearly full tank, run the engine to circulate it through the system, and change the fuel/water separator. For inboard engines, change the oil and oil filter to remove acidic contaminants. Flush the cooling system with fresh water and consider applying fogging oil to the cylinders for long-term storage.

Step 3: Protecting the Interior and Systems

Moisture control is paramount. Remove all cushions, sails, life jackets, and other soft goods for dry storage ashore. Prop open lockers and refrigerator doors to promote air circulation. Place moisture-absorbing desiccants or a dehumidifier in the cabin. Turn off all electrical switches and disconnect the battery, storing it in a cool, dry place on a maintenance charger. Ensure all seacocks are closed.

Step 4: Exterior and Hull Protection

Apply a high-quality wax to the hull and topsides to create a barrier against UV rays and pollutants. Cover the boat with a breathable, UV-resistant cover that is well-supported to prevent pooling water and chafing. Ensure the cover allows for ventilation to minimize condensation. If storing on a trailer, check tire pressure, lubricate the wheel bearings, and consider using jack stands to relieve tire stress.

Step 5: Choosing and Securing the Storage Location

The final step is selecting the right storage environment. Evaluate your options based on security, cost, and climate control.

Indoor Storage: Offers the best protection from sun and weather but is typically the most expensive.
Dry Stack Storage: A popular marina option where boats are stored on racks indoors or under cover, providing good security and convenience.
Outdoor Storage: The most economical choice, either on your own property (check local HOA rules) or at a secured lot. A high-quality, fitted cover is non-negotiable for this option.

Regardless of location, verify your insurance policy remains active and covers the specific storage scenario. Remove all valuables and document the boat's condition with photos before leaving it.

Step 6: Creating a Maintenance Schedule

Storing your boat is not a "set it and forget it" activity. Plan to visit periodically to check the cover, look for pest intrusion, ensure ventilation remains adequate, and verify the security of the vessel. This proactive approach allows you to address small issues before they become major problems.

By following these authoritative steps, you deliver maximum value to your boat's longevity and performance. Always consult your owner's manuals for model-specific guidance and confirm any facility requirements with your chosen storage provider.
