Ready, Set, Store: Off-Season Boat Storage Preparation Guide

Owning a boat can provide countless hours of enjoyment on the water, but it also requires a certain level of responsibility when it comes to maintenance and storage. One of the most important aspects of boat ownership is ensuring that your vessel is properly stored during the off-season.

This is particularly crucial in regions with harsh winter conditions, where extended exposure to freezing temperatures, snow, and ice can cause significant damage to your boat’s components and structure. Proper off-season storage not only helps maintain your boat’s value but also ensures a hassle-free start to the next boating season.

In this comprehensive article, we will discuss various aspects of off-season boat storage, including the importance of preparing your boat for storage, different storage options available, and the pros and cons of each method. Additionally, we’ll delve into the specific storage considerations for boats with sleeping quarters, as well as those without. Our goal is to provide you with a thorough understanding of the best practices for storing your boat during the off-season, so you can make informed decisions and enjoy many years of worry-free boating.

Now that we have set the stage, let’s dive into the details of off-season boat storage, starting with the critical steps you need to take before putting your boat away for the winter.

Preparing Your Boat for Storage

Before you store your boat for the off-season, you’ll need to take some essential steps to protect it from the elements and ensure it’s ready for use when the boating season returns. Here’s a checklist to help you prepare your boat for storage:

  1. Clean the boat: Thoroughly wash the exterior and interior of your boat, removing dirt, algae, and other debris. This will help prevent mold and mildew growth during storage. The link will take you to my article on cleaning the interior of a boat.
  2. Drain water from the boat: Remove any water from the bilge, water tanks, and other areas to prevent freezing and potential damage.
  3. Change the oil and filter: Perform an oil change to remove contaminants that can cause corrosion during storage. If you need more information on how to change your oil, check out my other article here which will answer all of your questions.
  4. Winterize the engine: Follow your engine manufacturer’s recommendations for winterizing your boat’s engine, which may include flushing the cooling system, adding a fuel stabilizer, and fogging the engine.
  5. Disconnect the battery: Remove and store the battery in a cool, dry place to prevent damage from cold temperatures.
  6. Prepare the fuel system: Fill the fuel tank to prevent condensation and add a fuel stabilizer to prevent gum and varnish buildup.
  7. Inspect and maintain the trailer (if applicable): Check the tires, brakes, and lights, and lubricate the wheel bearings and other moving parts.
  8. Protect against pests: Close any openings and use mothballs or other pest deterrents to keep rodents and insects away. If you’re not shrink wrapping your boat, then I highly recommend setting mousetraps inside your boat — LOTS OF THEM — especially if you have a berth (sleeping quarters)!
  9. Check and maintain safety equipment: Inspect life jackets, fire extinguishers, and other safety gear, replacing or servicing as needed.

Choosing the Right Storage Method

There are several storage options to consider for your boat during the off-season. The ideal method will depend on your boat’s size, your location, and your budget. Here’s a brief overview of the most common storage methods:

Indoor storage:

Storing your boat indoors in a garage, shed, or storage facility provides the best protection from the elements, but it can be costly and requires ample space.


  • Maximum protection from weather, UV rays, and pests
  • Easier access for maintenance and inspection during storage


  • Most expensive option
  • Requires ample space or access to a storage facility

Outdoor storage:

Storing your boat outdoors on your property or at a storage facility is a more affordable option but requires extra precautions to protect it from the elements.


  • More affordable than indoor storage
  • Suitable for larger boats that may not fit in a garage or shed


  • Less protection from weather, UV rays, and pests
  • Requires a high-quality cover

Dry stack storage:

Dry stack facilities store boats on high racks, protecting them from the elements and providing easy access when needed.


  • Good protection from weather and pests
  • Space-efficient and secure


  • Can be expensive, especially for larger boats
  • Limited access for maintenance and inspection during storage

Shrink wrapping:

Shrink wrapping your boat with a durable plastic film offers excellent protection from the elements, but it’s a temporary solution and may require professional assistance.


  • Provides excellent weather protection
  • Can be more affordable than indoor storage


  • Difficult to access the boat during storage
  • Requires professional assistance to apply and remove the wrap

Storing Boats with Sleeping Quarters vs. Boats without Sleeping Quarters

When storing a boat with sleeping quarters, there are a few additional considerations to keep in mind:

  • Ventilation: Ensure the cabin is well-ventilated to prevent mold and mildew growth. You can use moisture-absorbing products like silica gel or a dehumidifier to help maintain a dry environment.
  • Linens and soft goods: Remove any linens, cushions, and other soft goods from the boat and store them in a dry, climate-controlled area to prevent mold and mildew growth.
  • Appliances and electronics: Disconnect and clean appliances like refrigerators, microwaves, and air conditioners. Remove any portable electronics and store them in a dry, secure location.
  • Food and personal items: Remove all food items, toiletries, and personal belongings to prevent attracting pests and to avoid damage during storage.

For boats without sleeping quarters, the main difference is that there are fewer interior spaces to prepare and maintain. However, it’s still essential to properly clean, dry, and protect the boat’s interior from the elements and pests.

Final Thoughts

Properly storing your boat during the off-season is essential for maintaining its value and ensuring a hassle-free start to the next boating season. By following the steps outlined in this article, you’ll be well-prepared to store your boat safely, whether it has sleeping quarters or not.
