Professional Antifouling and Propspeed Services for Monohulls, Multihulls, and Cruising Yachts

Work with us

Regular antifouling is one of the most important maintenance tasks you can complete to protect the performance, fuel efficiency, and long term condition of your boat. Marine growth on the hull, propellers, and running gear increases drag, burns extra fuel, hurts sailing performance, and places unnecessary strain on your engines and cooling systems.

At Quayside Boatyard, we provide high quality antifouling and Propspeed services for monohulls, multihulls, launches, and cruising yachts. Our focus is on keeping your vessel performing at its absolute best below the waterline. Whether you are preparing for another great season cruising the Hauraki Gulf, heading offshore, or maintaining a wide beam cruising catamaran, our team is here to help.

Why Good Bottom Paint Matters

Antifouling is about much more than a clean look. Keeping your hull slick and free of growth directly improves:

  • Top speed and cruising performance

  • Fuel economy and engine efficiency

  • Sailing speed and light wind responsiveness

  • Essential hull and osmosis protection

  • Lower overall long term maintenance costs

A routine haulout also gives us the perfect opportunity to thoroughly inspect your hull, running gear, and through hulls, catching minor maintenance issues before they turn into expensive problems. For most boaties, the annual antifoul forms the true foundation of their vessel's preventative care.

Our Antifouling & Underwater Services

  • Every great paint job is only as good as the preparation beneath it. We do not cut corners on the dirty work. Our process includes:

    • Safe haulout and high pressure water blasting

    • Thorough scraping and wet sanding of the hull surfaces

    • A full assessment of your existing coatings to check for flaking or adhesion issues

    • Detailed inspections of the rudder bearings, cutless bearings, and skin fittings

  • We apply premium antifouling systems tailored specifically to your vessel type and how you use it. Whether your boat spends its weekends anchored in the Gulf, undertakes regular offshore blue water cruising, or sits on a mooring year round, we will help you choose the right hard, ablative, or foul release coating.

  • Propspeed is the gold standard for protecting underwater running gear from marine growth. Applied carefully to propellers, shafts, struts, rudders, and trim tabs, this specialized foul release coating keeps your metalwork completely clean.

    The benefits of a fresh Propspeed application include:

    • Significantly improved fuel efficiency

    • No marine growth binding up folding props or thrusters

    • A noticeable reduction in drivetrain vibration

    • Easier cleaning during subsequent haulouts

  • While your boat is blocked down on the hardstand, we can check and replace your zinc or aluminium sacrificial anodes, inspect the shaft seals, and ensure your grounding systems are completely secure to prevent galvanic corrosion.

  • Catamarans and trimarans present unique antifouling challenges due to their massive surface areas, dual running gear, and specific hull geometry. We regularly haul, prep, and paint leading multihull brands and custom designs, including:

    • Production Cats: Lagoon, Leopard, Fountaine Pajot, Outremer, and Catana

    • Performance & Custom Builds: Schionning, Gunboat, Grainger, Roger Hill, and Chris White designs

    Our team understands the importance of careful blocking and exact product application to keep cruising and performance multihulls sailing fast and efficiently.

Prepping for Blue Water Miles

Many cruising yacht owners use their haulout period to get their boats 100% ready for remote voyaging. Whether you are prepping for a Pacific circuit, an offshore passage, or long term liveaboard life, a clean hull and flawless running gear ensure your boat remains dependable when you leave New Zealand waters behind.

Frequently Asked Questions

  • For most local boats, a haulout and re-application is required every 12 to 24 months. This timeline depends on the type of paint used, how often the boat is sailed, and the water temperature at your home berth or mooring.

  • Yes, it makes a substantial difference. Because marine growth struggles to stick to the slick Propspeed surface, your propeller maintains its true pitch and efficiency, which directly lowers fuel consumption and prevents engine overloading.

  • Yes, absolutely. We pride ourselves on being a highly practical, DIY-friendly yard. You are welcome to take care of the painting yourself, or you can have our team handle the heavy prep while you apply the final coats.

  • We certainly do. Multihulls are one of our core specialties. We have the specific gear, wide hardstand spaces, and experience required to safely handle and paint large multihulls.

  • That is the best way to do it. Combining your annual bottom paint with mechanical servicing, through hull replacements, or hull polishing minimizes your total time out of the water and saves you money on transport and shipyard fees.
