Process
The heart of our underwater cleaning: Keelcrab is a remote-controlled drone that gently and thoroughly cleans your hull — right in the water, without haul-out.
After arrangement, we carry out the boat cleaning directly at the customer's location — in another marina, at the berth or even at anchor.
Keelcrab removes growth directly in the water — efficiently, material-friendly and without cranes or long downtime.
Enjoy better performance, lower consumption and a clean hull — all Keelcrab benefits at once.

Usable anytime
Control and cleaning directly in the harbor, at the berth or by arrangement at other locations — day or night.
Documented inspection
Photos, videos and documented conditions help with handovers, returns and insurance-relevant cases.
Ideal for charter
Especially in season, when guests change constantly, charter companies save time and can quickly check the underwater condition.
Then let's talk about a flexible solution for your fleet or your location. Our systems are also suitable for documented inspections — e.g. at handovers, returns or insurance-relevant damage.
