Storing Your Vessel: A Comprehensive Guide to Boat Storage Unit Sizes

‍Boating enthusiasts understand that the off-season can pose a significant challenge. Where should you keep your beloved watercraft when it’s not in use? The answer lies in self-storage units designed specifically for boats. However, the size and type of your boat dictate the appropriate storage unit dimensions. This article will guide you through the common storage unit sizes for boats and offer tips for boat preparation before storage.

Understanding Boat Storage Unit Sizes

While the actual size of storage units can fluctuate based on the facility, there are three standard sizes typically used for boat storage.

10×20 Storage Units: For the Smaller Watercraft

These units are a match made in heaven for small boats, such as dinghies, jet skis, and canoes. Apart from your watercraft, you can also accommodate small trailers and miscellaneous accessories within this size.

10×30 Storage Units: Room for the Bigger Fish

For those who own larger boats such as fishing boats, pontoons, and small motorboats, a 10×30 storage unit is an ideal choice. It also provides ample space for trailers and accessories.

12×35 Storage Units: The Ultimate Space for Large Boats

If you’re a proud owner of a large boat like a yacht or sailboat, the 12×35 storage units are the best fit. These units can also accommodate trailers and accessories.

Note: Always measure your boat’s height, width, and length before selecting a storage unit. These dimensions will ensure your boat fits comfortably inside.

The Importance of Boat Preparation Before Storage

Storing your boat isn’t as simple as parking it inside a storage unit. Proper preparation is crucial to maintaining your boat’s good condition.

Cleaning Your Boat

Before bidding adieu to your boat for the off-season, ensure it’s clean. A thorough wash will prevent any existing dirt or salt from damaging the boat’s surface over time.

Draining All Water

Drain all water from the boat to prevent freezing and damage during the colder months.

Removing the Battery

To prolong the battery’s life, remove it and keep it in a warm, dry place.

Using a Boat Cover

A suitable boat cover protects your boat from dust, pests, and moisture.

Adding a Fuel Stabilizer

A fuel stabilizer prevents the fuel from breaking down during the storage period.


In conclusion, selecting the appropriate storage unit for your boat depends on the boat’s size and type. Always measure your boat before choosing a storage unit and ensure it is prepared properly for storage. This preparation will ensure that your boat remains in good condition while it’s stored away.
