What you need to know


 What is boat antifouling?

Antifouling is the process of protecting your boat’s hull from marine growth by applying a protective paint layer to the bottom of your boat.

Antifouling is the most common (and arguably the most critical) job when it comes to boat maintenance, because once fouling has a hold on your hull it will rapidly colonise the surface, making it difficult to remove.

Applying an antifouling paint will prevent the attachment of fouling organisms, such as barnacles, weeds and slime, to the hull of your boat. A fouled hull can cause serious problems, therefore prevention is much better than cure.


 Common questions about Antifouling

How is antifoul paint applied?

Antifoul paint can be applied by brush, roller or spray. Rolling application is the most common and when done right, achieves great results. The spraying application is slightly more expensive but popular for those looking to achieve a racing-like finish. It is vital to have the application process done correctly to ensure the paint thickness and bond is consistent with manufactures recommendations. It is important as this results in a smoother finish ultimately delivering better fuel economy and antifoul longevity.

How often should I antifoul my boat?

To ensure a boat is well looked after the answer is approximately every 9-15 months, depending on how frequently the boat is used, where it lives and the harshness of that environment.

However it seems there is still that minority out there who push the boundaries in an attempt to save a few pennies. But in fact, that’s not that case.

What we are seeing more and more often are customers who bring their boat in to be antifouled 18-24 months later and commonly find more issues with the boat, which is costing them more money in the long run.






What can happen if you don’t antifoul your boat reguarly?

When a boat owner has pushed the limits regarding booking their vessel in for a clean, antifoul and anode replacement, here are some of the issues that we commonly find:

Fiberglass Damage

Excessive growth becomes difficult to remove once the barnacles have stuck to the fiberglass underneath the antifoul.


Sacrificial anodes play a crucial role in avoiding corrosion to all propellers, shafts, stern drives, trim tabs and rudders. If these are not replaced annually the risk of corrosion to the running gear is greatly heightened.

Engine Overheating

Raw water intake blockage is one of the most common contributors to an engine overheating. This can be avoided by the clean out and re-antifouling of all intakes and skin fittings. This is all included in the process when a boat is antifouled.

Fuel Consumption

As the growth underneath the hull continues to build up, so does your fuel consumption. It causes increased drag, and in turn, the boat travels much slower because it requires more engine power. There have been cases where excessive growth has been responsible for fuel efficiency dropping by 50%.

More often than not, delaying antifouling will NOT save you money. In fact, it will actually cost you more in the long run! So go on, give your boat the care it deserves.
