Storing a boat outdoors is certainly possible, but there are some important factors to consider in order to properly protect and maintain your boat. Proper preparation and maintenance are key when keeping a boat outside for any length of time.
Is it okay to store a boat outside?
Yes, boats can be safely stored outside with the right precautions taken. Many boat owners keep their boats outdoors on trailers, on boat lifts, or at marinas or yacht clubs. However, outdoor storage does expose boats to the elements, so additional maintenance and preparation is required compared to storing a boat indoors.
Advantages of outdoor boat storage
- Convenience – boats are easily accessible for launching and using
- Cost – outdoor storage is often cheaper than indoor storage options
- Ventilation – airflow can help prevent mold and mildew
Disadvantages of outdoor boat storage
- Weathering – boats are exposed to sun, rain, wind, etc. which can cause damage over time
- Debris – outdoor areas collect falling leaves, dirt, bird droppings, etc.
- Security – boats outdoors are more easily tampered with or stolen
Preparing a boat for outdoor storage
Properly preparing a boat for seasonal or long-term outdoor storage is crucial. Here are some tips for getting a boat ready for outdoor storage:
Cleaning
- Wash the boat hull, deck, cockpit thoroughly to remove dirt, grime, salt deposits, bird droppings, etc.
- Clean out all onboard compartments and lockers
- Vacuum and shampoo carpets, cushions, and upholstery
- Drain the bilge completely
Inspection and repairs
- Check the hull, thru-hulls, seacocks for any cracks or leaks
- Inspect and repair fittings, fasteners, cleats, rails
- Test engine and electrical systems, repair any issues
- Check and lubricate seacocks, shafts, drivetrain
- Pump out holding tanks and add biocide
Protection
- Apply wax to the hull and nonskid deck areas
- Buff and protect metal fittings, hardware
- Coat and lubricate electrical connections
- Fill fuel tanks to prevent condensation
- Fog the engine with a corrosion inhibitor
- Install a boat cover properly secured at all points
Taking the time to thoroughly clean, repair, and protect your boat will help prevent damage during outdoor storage.
What kind of boat is best for outdoor storage?
Fiberglass powerboats and sailboats generally hold up the best for long-term outdoor storage. Consider the following:
Fiberglass hull
- Gelcoat is durable and resists weathering and UV damage.
- Requires minimal maintenance compared to wood hulls.
- Easy to clean, polish, and wax.
Modern deck hardware
- Stainless steel and aluminum hold up better than brass, chrome.
- Created for marine environments.
- Withstands weather extremes.
Good cover or mooring system
- Full boat cover or tarp system secured at all points.
- Covered slip or indoor/outdoor rack storage at a marina.
- Well-designed boat lift or cradle system.
The main goal is protecting the boat from sun, rain, wind, and debris. A fiberglass boat with fitted canvas and modern deck hardware can endure outdoor storage with proper care and maintenance.
Considerations for storing a boat outdoors
Here are some important factors to keep in mind when storing a boat outside:
Sun and UV exposure
- Sunlight and UV rays damage boat surfaces and fade fabrics over time.
- Moor boat so it doesn’t sit with one side facing the sun.
- Use fitted cover or mooring canopy to provide shade.
Rain and snow
- Precipitation can leak through small gaps and cracks.
- Regularly check under the cover for any puddles or damp spots.
- Use support poles to create a slope for drainage.
- Make sure ice and snow don’t accumulate on the cover.
Wind
- Flapping and rubbing from cover material or ties will wear the hull gelcoat.
- Wind can rip poorly secured covers and cause damage.
- Use tight cover with integrated ties and under-cover poles.
Debris
- Outdoor areas collect dirt, leaves, bird droppings, etc.
- Regularly clean off any debris to prevent staining or damage
- Park boat away from trees that will drop sap, leaves, or berries.
Temperature and humidity
- Heat and humidity promote mold growth, mildew, and oxidation.
- Ventilate under the cover to allow airflow.
- Use anti-mildew sprays on carpeting.
- Keep the bilge clean and dry.
Pests
- Mice, birds, insects, spiders may nest onboard.
- Seal all openings to make boat as rodent-proof as possible.
- Use traps, deterrents, and pest-control services as needed.
Accounting for these environmental factors will help you take the necessary steps to protect your boat properly while outdoors.
Outdoor storage options for boats
There are several common outdoor storage solutions for boats to choose from, each with their own pros and cons:
Dry storage
- Trailer – Easy to launch, transport boat. Provides good ventilation. The least protective option.
- Cradle – Supports hull, adjustable height. Usually uncovered so minimal protection.
- Rack system – Stores boats in racks on land. Adjustable heights. Uncovered boats exposed to elements.
- Boat lift – Raises boat out of water when not in use. Minimal protection from rain, sun.
Wet storage
- Mooring buoy – Boat stays on open water. Requires frequent use to check lines, chafe.
- Dock slip – Protects sides of boat but open above. Easy to access and use.
- Pole lift – Moors boat in slip so it rises and falls with tides. Debris falls between boats.
Indoor storage
- Rack storage – Enclosed rack systems fully protect boat. Most secure option.
- Warehouse – Boat stored indoors on trailer. Complete protection from elements.
Indoor storage provides the most protection, but outdoor options offer more convenience and lower cost. Evaluate each option based on your specific needs.
Preparing for winter outdoor storage
Winterizing preparations are crucial when storing a boat outdoors in colder climates. Follow these additional tips to prep for winter:
- Perform fall maintenance service – change fluids, inspect components, test systems.
- Winterize the engine – drain cooling system, add antifreeze, fog cylinders, change oil.
- Winterize plumbing – drain freshwater system, add RV antifreeze.
- Fully charge batteries and remove for indoor storage if possible.
- Seal all openings – hatches, covers, snaps, storage compartments.
- Secure cover from all angles to seal out water completely.
- Use support frame or poles to prevent sagging from snow load.
- Consider storing the boat on land or indoors if possible.
Taking extra time to winterize your boat will help prevent costly freeze damage during frigid winters.
Regular maintenance for outdoor stored boats
Sticking to a consistent maintenance schedule is imperative for boats stored outdoors long-term. Perform the following tasks regularly:
Monthly
- Wash boat down thoroughly
- Inspect cover for wear or rubbing
- Check for leaks, dampness, or water intrusion
- Remove all leaves, debris, bird droppings
- Check bilge water levels
Every 2-3 months
- Wax the hull and apply UV protectants
- Flush the engine with fogging oil
- Spray vinyl and canvases with protectant
- Run electronics and equipment briefly
- Recharge or change batteries
- Inspect all fittings, lines, and connections
Off season
- Do thorough cleaning, waxing and detailing
- Complete maintenance items and repairs
- Change engine fluids and filters
- Have professionals inspect mast, spars, sails
- Replace sacrificial anodes on hull and metal components
Staying diligent with routine maintenance will extend the life of your boat despite being exposed to the outdoor elements.
Tips to prevent damage when storing a boat outside
Here are some useful tips to help prevent damage while storing your boat outdoors:
- Invest in a high-quality boat cover or mooring system designed for outdoor use.
- Avoid using tarps or temporary covers that can rub against the hull.
- Secure the cover tightly at all points to seal out water.
- Use padding on tie-downs or rails to prevent rubbing.
- Ventilate under the cover to reduce condensation and moisture.
- Use breathable fabrics like Sunbrella instead of vinyl tarps.
- Tie down or remove bimini tops and dodgers to prevent wind damage.
- Use frames or poles to keep covers off surfaces.
- Store boat on land if possible to improve ventilation.
- Park under structures or trees to reduce direct sunlight if possible.
Taking steps to protect your boat from the elements will go a long way in maintaining its condition when outdoor storage is your only option.
When is indoor storage recommended over outdoor storage?
Indoor storage is recommended over outdoor storage in the following situations:
- New or classic boats – Protect investment and maintain showroom condition.
- Wooden boats – Wood hulls are very prone to weather damage outdoors.
- Boats in saltwater areas – Salt air causes extensive corrosion issues.
- Regions with extreme weather – Severe winters, wind, hailstorms, etc.
- Often absent owners – Unable to frequently check on boat.
- Valuable electronics/gear onboard – Vulnerable to theft and tampering.
- Marinas or shared docks – Boats clashing together causes scratches.
- Birds, rodents, and pest problems – Infest interior spaces.
The complete protection from the elements provided by indoor storage can be well worth the additional cost for certain boats and owners.
Conclusion
Outdoor storage is a viable option for many boat owners if proper maintenance and protection steps are taken. Fiberglass powerboats and sailboats with fitted covers designed to be outdoors can endure seasonal and long-term outdoor storage with regular cleaning and preventative care. However, indoor storage does provide the ultimate protection and security for valuable boats or those in harsh environments. Assess your specific boat type, climate conditions, storage duration, and maintenance capabilities when deciding between indoor vs outdoor options.
