How do you store an Aluminium boat?

Storing an aluminum boat properly is crucial to maintaining its condition and value over time. Improper storage can lead to corrosion, fading, cracking, and other damage. By following some basic guidelines, you can keep your aluminum boat in great shape during the off-season or when not in use.

Why Proper Storage Matters

Aluminum boats are susceptible to corrosion and oxidation when exposed to weather and moisture. This can cause pitting, discoloration, and rust on the hull, leading to leaks or even hull failure over time. Additionally, the marine environment is very hard on boats. Saltwater, UV rays, changes in temperature/humidity, and even airborne pollutants can gradually degrade and damage aluminum over an extended period.

Proper storage gets your boat up off the ground, shields it from the elements, and prevents prolonged exposure to moisture and condensation. This keeps it looking great and maximizes its lifespan. Putting in a little time and effort upfront will pay off every time you use your aluminum boat for years to come.

Location

Choosing the right location is the first key factor for proper storage. The main goal is keeping your aluminum boat covered and protected from rain, snow, sun, wind, and other environmental factors. Here are some good options to consider:

• Covered boat shed or garage – This is ideal if you have access to an enclosed, covered structure on your property. Be sure no chemical vapors or lawn/garden chemicals are stored in the same building.
• Carport or pole barn – While not fully enclosed, these structures will provide good cover from above.
• Boat storage facility – There are specialized storage facilities and marinas that offer secure indoor or covered outdoor storage spaces for boats.
• Contract an outdoor storage service to shrink wrap your boat.

Avoid storing your aluminum boat directly on the ground or with a basic tarp cover if possible. Moisture can easily collect and lead to corrosion.

Blocking

Once you’ve chosen a good location, use blocking to get your boat off the ground. Pressure points where the hull contacts the ground can lead to indentations, cracks, or distortion over time. Here are some blocking options:

• Wood blocks – Oak, pine, or marine-grade plywood blocks. Use at least three along the length of the hull.
• Jack stands – Purchase boat jack stands or trailer jack stands to securely lift the hull.
• Tires – Place several tires under the hull if storing on a hard surface.
• Racks – Store on a boat storage rack or lift system.

The blocking should lift the hull evenly 4-6 inches above the ground. Inspect blocking for sagging or settling periodically. Shirting can put excess stress on the hull.

Supporting

In addition to blocking the hull, it’s important to properly support other components of your aluminum boat:

• Trailer: Ideally, leave the boat on its trailer if storing for less than 6 months. Use jack stands to take the weight off the tires. Cover the tires to avoid dry rot.
• Canopy: Remove canvas canopies and store separately indoors. Fully collapse folding frames.
• Outboard motor: Remove and store separately if possible. Otherwise, make sure the motor is fully vertical and cover it.

This safeguards other components from damage while elevating the hull.

Stabilizing and Securing

A few other tips will keep your boat stable and secure during storage:

• Tie it down – Use rope or ratchet straps to securely tie the boat and trailer to fixed points, avoiding excess tension or stress.
• Chock the wheels – Place sturdy wood wheel chocks or blocks behind the wheels.
• Lower the keel – Empty ballast tanks to lower the keel and center of gravity.
• Position bow high – Face the bow slightly uphill to promote drainage.

This will prevent shifting, sliding, tipping, or rolling during the storage period. Perform regular checks on tie-downs and equipment as seasons change.

Cleaning and Protecting the Hull

Before storage, thoroughly clean and protect the hull using these steps:

1. Wash the hull, deck, and interior with a boat soap and water. Rinse thoroughly.
2. Use a wax and polish to buff the hull and build up a protectant layer. Avoid waxing non-skid areas.
3. Apply a corrosion inhibitor or barrier coating like a rust preventative lubricant.
4. Allow surfaces to completely dry before covering.
5. Install a storage cover tightly over the boat to seal moisture out.

This cleaning regimen prevents mold, mildew, and shield against moisture damage during storage.

Fuel and Fluids

To avoid problematic leaks or spills, properly remove/treat all fluids:

• Drain the fuel tank and fuel lines completely or add fuel stabilizer to prevent gumming.
• Change all engine oils and filters prior to storage per the manual.
• Drain cooling water and add antifreeze for winterization if needed.
• Charge batteries fully and disconnect terminals or remove batteries.

Checking for leaks, fumes, or other issues during storage can prevent major problems when reactivating your boat.

Ventilation and Moisture Control

While covered storage protects the hull, excess moisture can still build up inside a boat. Reduce interior humidity using these tips:

• Remove all cushions and open cabinets/lockers to increase air circulation.
• Place moisture absorbing desiccant packs in the bilge and interior spaces.
• Crack open hatches or install ventilation systems to allow airflow.
• Install sump pumps to remove any collected moisture.

Frequent checks for mildew odors or visible moisture will allow you to take corrective action.

Maintenance and Inspections

No boat storage method is completely maintenance-free. Build regular checkups into your storage plan:

• Inspect blocking/supports every 2-3 months for issues.
• Remove covers and air out the boat at least once mid-storage.
• Charge batteries monthly to avoid sulfating.
• Change engine oil and cycle engines if storing for over 6 months.
• Check tire air pressure and condition if on the trailer.
• Ensure covers remain tight and gaps/tears are repaired.

Being vigilant saves you from more intensive repairs later on. Develop a checklist tailored to your specific boat and storage conditions.

Recommissioning After Storage

When it’s time to use your boat again, proper launch and recommissioning ensures everything is shipshape:

• Charge and reconnect batteries fully.
• Install and fuel engines – perform all pre-launch checks.
• Pump antifreeze from systems and flush with freshwater.
• Install canvases, cushions, and accessories.
• Rig mast, sails, and inspect lines/wiring for issues.
• Carefully unblock and launch the freshly protected hull.

Address any new corrosion, leaks, damage, or problems before enjoying your first post-storage voyage.

Professional Storage

For worry-free storage, consider hiring professionals. Many marinas and dealers offer subsidized offseason packages. Benefits include:

• Indoor heated/insulated facilities.
• Access to forklifts, dollies, and equipment.
• Experienced staff handle all preparation and maintenance.
• Better security against theft and vandalism.
• Onsite mechanics for recommissioning services.

Shop around as prices and specific services can vary. Weigh the cost against peace of mind and your own time invested.

Key Takeaways

Storing an aluminum boat properly involves choosing a protected location up off the ground, removing or securing components, cleaning/protecting the hull, addressing fluids, controlling moisture, and periodic maintenance. This prevents corrosion, damage, leaks, and other problems. With the right preparation, your boat will launch in pristine, like-new condition season after season.

Conclusion

By implementing practical and thorough storage procedures, you can maintain the good condition and performance of your aluminum boat during periods of non-use. While boat storage requires an initial investment of time, effort, and workspace, the long-term rewards are well worth it. Use this guide to develop a customized storage plan for your specific boat and climate conditions. With careful drying, covering, blocking, fluid management, and regular maintenance, your boat will stay in great shape until you are ready set sail again.
