Owning a boat in Australia is a fantastic lifestyle choice. Whether you enjoy fishing, cruising, or weekend family trips, your vessel is a valuable investment. However, improper storage can lead to serious damage and expensive repairs.
Understanding the common boat storage mistakes and how to avoid them will help you protect your boat from harsh weather, corrosion, mould, and security risks. Below, we break down the most frequent errors boat owners make and provide practical solutions to keep your boat in top condition.
Why Proper Boat Storage Is Essential in Australia
Australia’s climate can be unforgiving. From intense UV exposure in WA to coastal salt air and heavy seasonal rains, boats left unprotected can deteriorate quickly.
Poor storage can result in:
- Faded gelcoat and cracked upholstery
- Rust and corrosion
- Engine failure
- Electrical system damage
- Mould and mildew buildup
- Theft or vandalism
Avoiding these risks starts with understanding what not to do.
Mistake #1: Not Cleaning the Boat Before Storage
One of the most common boat storage mistakes is putting the boat away without proper cleaning.
Why It’s a Problem
- Saltwater causes corrosion
- Organic debris encourages mould
- Dirt can stain surfaces permanently
How to Avoid It
Before storing your boat:
- Rinse thoroughly with fresh water
- Use marine-grade cleaning products
- Remove all food and rubbish
- Allow the interior to dry completely
A clean boat is far less likely to develop long-term damage.
Mistake #2: Ignoring Engine Preparation
Failing to prepare the engine for storage is a costly error.
Risks Include:
- Fuel degradation
- Internal corrosion
- Battery failure
- Oil contamination
Proper Engine Storage Steps
- Flush engine with fresh water
- Add fuel stabiliser
- Change oil and filters
- Disconnect or remove battery
- Check coolant levels
If unsure, consult a qualified marine mechanic before long-term storage.
Mistake #3: Using a Cheap or Incorrect Boat Cover
Many owners use low-quality tarps that trap moisture.
Why This Causes Damage
- Condensation leads to mould
- Poor fit causes chafing
- UV damage continues through thin material
The Right Approach
Choose a cover that is:
- UV-resistant
- Breathable
- Properly fitted
- Securely fastened
A high-quality cover significantly extends your boat’s lifespan.
Mistake #4: Storing the Boat in an Insecure Location
Leaving a boat parked on the street or in an open driveway increases the risk of theft.
Common Security Oversights
- No wheel lock
- No hitch lock
- No gated access
- No surveillance
How to Avoid Theft
- Install trailer locks
- Remove valuables
- Lock compartments
- Store in a secure, monitored facility
Professional boat storage facilities provide added peace of mind.
Mistake #5: Forgetting About Moisture Control
Moisture is one of the biggest threats during storage.
Problems Caused by Moisture
- Mould growth
- Upholstery damage
- Electrical corrosion
- Rust on metal components
Prevention Tips
- Ensure boat is completely dry
- Use moisture absorbers
- Leave ventilation gaps where safe
- Check the boat periodically
Regular inspections can prevent minor issues from becoming major repairs.
Mistake #6: Leaving the Fuel Tank Nearly Empty
Many boat owners believe draining fuel is best. In reality, a nearly empty tank can cause condensation inside the tank.
Correct Practice
- Fill the tank close to full
- Add fuel stabiliser
- Run engine briefly to circulate stabiliser
This reduces moisture buildup and protects the fuel system.
Mistake #7: Ignoring Trailer Maintenance
Boat storage isn’t just about the vessel — the trailer matters too.
Common Trailer Storage Errors
- Underinflated tyres
- Rusted brakes
- No wheel chocks
- Flat spots on tyres
Proper Trailer Care
- Inflate tyres to recommended pressure
- Use wheel chocks
- Lubricate moving parts
- Move trailer occasionally if stored long-term
Well-maintained trailers ensure safe transport when boating season returns.
Indoor vs Outdoor Storage: Making the Right Choice
Choosing between indoor and outdoor boat storage impacts long-term protection.
Indoor Storage Benefits
- Maximum weather protection
- Reduced UV exposure
- Lower long-term maintenance
Outdoor Storage Benefits
- More affordable
- Easier access
- Suitable with high-quality covers
Your choice depends on budget, duration, and local conditions.
