Welcome to KeelCrab

Traditional methods offer complete and manual cleaning operations, sometimes underwater or sometimes across hauling and launching activities. KeelCrab is a new method for leisure boats hull that does want to integrate the ordinary maintenance by reducing extraordinary interventions in the medium term. For this reason divers and shipyards integrate our system into services offered to customer.

We provide a nylon filter bag in several micrometer size (180 micron or 50 micron) to recover waste material, algae or vegetation produced by the cleaning operation.

The drone cleans 95% of the hull surface: hull and rudder. Floating discs allow the drone to move vertically from hull to keel and rudder.

In order to maintain the propeller clean (aft feet as well), we provide the Ultracrab. It's an ultrasonic antifouling device easy to install on the stern: the constant propagation of high frequency and variable power sound pulses prevents algae formation.

Thanks to KeelCrab App available for IOS and Android Store, you can watch the hull inspection from the KeelCrab camera and record it.

Our brushes are designed to remove algae vegetation and collect it in bag without removing antifouling.

A regular service prevents the growth of barnacles. 

Considering a 2,5 m²/min velocity, the drone cleans a 12 meters boat lenght (40 feet) in 1,5 hour, a 18 meters boat lenght (60 feet) in 2 hours, a 24 meters boat lenght (80 feet) in 3 hours.

Keelcrab is powered with a 20 mt kevlar cable and uses a plug suitable from 110 V to 220 V for the standard of marinas worldwide. We provide a standard plug for marinas worldwide, plus the possibility to request a kit for inverter generator to use remotely. The only alternative is using an electric generator: solar panels currently are not able to support the power usage of the drone.

We provide a remote controller connected to the drone with 7" display, joystick and 7 meters cable. You can also stream the camera feed to your smartphone with the Wi-Fi Mobile Connectivity kit (standard on the Pro Pack).

We provide three different brushes for three different levels of cleaning: white soft nylon brush; yellow medium nylon brush and stainless brush.

Before replacement the brushes last about 100 hours, longer if the cleaning is performed on regularly maintained boats and not on hard fouling.
