The Performance Gap
The Truth Behind The “Performance Gap”
Traditional maintenance, whether it’s a yearly haul-out or calling a diver every few months, is typically a reactive response to a dirty hull. You wait until the boat feels slow or the growth looks "bad enough" to act.
That wait creates a Performance Gap. From the moment your hull is cleaned, the ‘slime tax’ starts building again. The longer you leave it untouched, you end up paying for it in wasted fuel and lost speed.
With Hull Guardian, you’re staying ahead of the problem instead of reacting to it.
Keeping You Fast & Efficient
Our subscription service lets you choose how often you want your hull cleaned to optimize your vessel’s performance to the way you want it. Whether you’re racing, fishing or cruising the country, we’re able to tailor a plan that works for you.
Set and Forget Management
Hull Guardian replaces reactive scrubbing with proactive robotic grooming. Using state of the art ROV technology, we maintain your hull at LOF Level 1 (Slime-Free) on a customized, recurring rotation.
Our soft-foam technology wipes away biofilm without scratching your gelcoat or degrading your antifoul. Your paint lasts significantly longer.
We don't pollute your marina. Our system features a closed-loop 50-micron vacuum that captures biological waste for safe, land-based disposal.
We take the guesswork out of hull maintenance. After every groom, we send a visual report with clear before-and-after photos and key video snippets of your hull, running gear, and intakes straight to your phone
Vessel Performance
A fouled hull creates hydrodynamic drag, forcing your engines to work harder to reach cruising speed. Proactive cleaning keeps your hull hydro-dynamically smooth. This eliminates unnecessary engine load, reduces long-term wear on your machinery, and improves fuel efficiency by up to 20%.
Cost Saving
Traditional maintenance is reactive and expensive. By actively removing micro-fouling before it becomes established, we protect and extend the effective lifespan of your antifoul coating. A Hull Guardian subscription can push back your expensive boatyard haul-outs and hardstand schedules by months or even years, saving you thousands annually.
Peace of Mind
Operate with zero guesswork. Our closed-loop robotic system captures bio-waste down to 50 microns, aligning with New Zealand’s Marine Biosecurity rules. After every service, you receive our 'Guardian Diagnostic' report complete with before and after photos and key video clips of your hull and running gear, giving you absolute confidence in your vessel's condition.
What This Actually Means
For the Power Crew: Range & Reliability
If you’re running a motor, drag is your biggest enemy.
Save on Diesel: Slime and foul build up can increase your fuel burn by 15% to 20%, sometimes more. Keeping your hull clean gets you further for less.
Protect Your Gear: It’s not just about fuel. When the hull is dirty, your engines, gearboxes, and shafts are under constant increased pressure. Robotic grooming takes the load off your running gear, resulting in less mechanical stress and a longer life for your drivetrain.
Keep Your Speed: Your boat was built for performance. A clean hull helps ensure you get those top-end knots when you need them.
For the Sailing Fleet: Precision Matters
Whether you’re cruising or racing under sail, every knot counts.
Stay Fast All Season: Peak performance comes from efficiency and a clean hull gives you the edge you need, potentially reclaiming 2 to 3 knots of speed.
Staying Unstuck: A clean hull keeps you moving when others are stuck, ensuring your trim is perfect whether you're on the start line or heading to the islands.
Preserve Your Coating: Our robot uses soft-touch nylon brushes that groom the surface ensuring no scouring. It keeps the finish slick for the racecourse and extends the life of your paint for the cruising season, meaning more time between haul-outs.
