What Counts as 'Heavy Fouling'?

Thick marine growth identified by a combination of barnacles, oysters, hard shell buildup, dense algae, and long grass that covers large sections of the bottom. This level of growth requires significantly more time and effort to remove and may require multiple passes or specialized tools. Owners will be notified of heavy fouling before any transaction.

Our Tools Make The Difference

We invest in professional-grade diving equipment so your boat receives a cleaner, safer, and more consistent service every time.

Nemo Soft Brush Hull Cleaner

We use a diver-controlled soft-brush system engineered for today’s bottom paints—gentle enough for ablative coatings and precise enough for high-performance hulls. It maintains perfectly even, controlled pressure that hand-scrubbing can’t match, giving you a cleaner bottom with less wear on your paint.


Think of it like a soft-brush car wash for your hull—consistent and gentle—but with every move guided by an experienced diver for maximum safety and precision. For tougher, hard growth, we switch to traditional hand tools to protect your coatings. 

Air Line E160V2 Hookah Diving System

Our tankless diving system provides continuous, Grade-E breathable air, allowing us to work longer and more safely underwater. No tanks, no rushed worked. Just steady, focused maintenance performed by a trained diver.

Professional Manual Tools for Running Gear

Props, shafts, struts, trim tabs, and intakes require a skilled touch. We use a refined mix of specialized brushes and polishing pads, giving our divers the control they need to thoroughly clean running gear while protecting sensitive surfaces.

Why This Matters for You

Better tools mean:

  • A cleaner, faster service
  • Less wear on your bottom paint. No fluctuations in pressure.
  • Safer and more controlled care for running gear
  • A consistently higher standard of underwater maintenance


We combine advanced diver-operated tools with skilled hands to deliver a premium, meticulous service every visit.
