Protecting Australian Waters: A Simple Guide to Biofouling Prevention for Vessel Owners
At Gold Coast City Marina & Shipyard, we understand that caring for your vessel is more than just good practice—it’s part of protecting Australia’s beautiful marine life. Biofouling, or the build-up of marine growth on your boat’s hull and underwater parts, can slow down your vessel, increase fuel use, and risk spreading harmful invasive species.
What is Biofouling and Why Does it Matter?
Biofouling is the term for when marine life—like algae, barnacles, and mussels—sticks to your boat’s submerged surfaces. It starts quickly, with tiny films forming in hours and larger growth building up over time.
Ignoring biofouling can cause several problems:
– Environmental harm: Invasive species hitch a ride and damage our native marine ecosystem.
– Bigger bills: Increased drag can reduce fuel efficiency by more than 10%, leading to higher running costs.
– More maintenance: Severe build-up means harder, more expensive cleans.
– Risk to industries: Fisheries and seafood businesses are under threat from introduced species.
Keeping your vessel clean is essential not only for smooth sailing, but also to protect what makes Queensland waters unique.
Key Biofouling Prevention Steps
- Regular Vessel Checks
Inspect your vessel after outings—especially hulls, propellers, rudders, intakes, and underwater gear. Note any growth, take photos, and keep detailed records. This helps you spot trends and keep track of maintenance.
- Professional Antifouling
The right antifouling paint forms a barrier against marine growth. Choosing the best product depends on your boat type, where you go, and how often you haul out.
At GCCM, our expert team works closely with trusted paint brands to match the ideal solution to your vessel and local conditions. Our process includes:
– Thorough cleaning and assessment
– Repairing any hull damage
– Applying primers and antifouling coatings for long-lasting results
- Keep Good Records
Document all your maintenance, including inspections, cleanings, and antifouling work—with dates, details, and photos. Good records help with:
– Planning future maintenance
– Proving regulatory compliance
– Giving peace of mind to future buyers
- Clean Responsibly
Always clean your vessel in approved, land-based areas—like hardstands with wastewater collection. This prevents harmful residues and organisms from reaching waterways.
GCCM’s 50,000m² controlled hardstand is purpose-built for safe, eco-friendly cleaning. We capture and treat all runoff to protect our environment.
- Manage Wastewater Properly
Contain all wash water and debris, filter contaminants, and follow local waste disposal rules. Even small amounts of contaminated water can spread invasive species.
- Stay Alert for Marine Biosecurity
Learn to spot key invasive species—like Asian green mussels and Northern Pacific seastars—and know how to report them. If you see something unusual:
– Take clear photos
– Record the location and date
– Notify local biosecurity authorities
Early reporting helps stop new pests before they become a bigger problem.
