Traditional methods offer comprehensive, manual cleaning operations, sometimes underwater or sometimes during hauling and launching activities. KeelCrab is a new method for the hull of recreational boats that aims to complement routine maintenance by reducing medium-term extraordinary interventions. For this reason, divers and shipyards integrate our system into their customer services.

Keelcrab is powered by a 20 m Kevlar cable and uses a plug suitable from 110 V to 220 V by the standard for marinas worldwide. We provide a standard socket for marinas around the world, as well as the option of requesting an inverter generator kit for remote use. The only alternative is to use an electric generator-solar panels currently cannot support the drone’s energy use.

We provide a nylon filter bag in several micrometer sizes (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.

To keep the propeller (even the stern feet) clean, we provide Ultracrab. It is an ultrasonic antifouling that is easy to install at the stern: the constant propagation of high-frequency, variable-power sound pulses prevents algae formation.

With the 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 a bag without removing the antifouling.

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 hours, a 18 meters boat lenght (60 feet) in 2 hours, a 24 meters boat lenght (80 feet) in 3 hours.

We provide a remote control connected to the drone with 7″ display, joystick and 7-meter cable. You can also transmit 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, brushes last about 100 hours, longer if cleaning is done on regularly maintained boats and not on hard fouling.

KEELCRAB ONE (for Private Boatowner) starts from 2586 EUR and KEELCRAB PRO (full optionals pack for Yacht Business & Professionals) starts from 4386 EUR that include also the Point Affiliation Program.

Please note that these prices are subject to change and may not include VAT or shipment costs.

We accept wire transfer and credit card payment (subjected to a 4% commission by card).

Why Keelcrab is Different?

Keelcrab offer different solutions to improve the maintenance of you Yachts: the Keelcrab Drones allow you to clean safer out of the water driving the drone to clean the hull; the antifouling and hydrophobic paintings allow your yacht to maximize your performance on the water and protect the hull from algae and corrosion.

KeelCrab PRO 23: Our latest upgrades

Motorized vertical brush

We improved the experience of hull cleaning!

The motorized vertical brush is counter-rotating cushioned disc brush kit (15mm excursion/adaptation to surface) driven by dedicated waterproof motor with variable bristles (two nylon discs as standard and optional stainless steel discs ordered separately) to increase the cleaning capabilities of your robot.

 

Diver Pack

Let’s discover fundamental functionality of Diver Pack 

The diver pack is a kit for using your keelcrab in “manual control” mode while diving (apnea or ARA/ARO). The kit consists of 2 side handles and a backlit switch / IP69 switch for operating the traction motors (to be able to activate or stop the robot’s advancement and the relative dragging effect of the diver in the hull).

With this accessory, you can save effort and time during cleaning operations carried out underwater by using a real underwater mower that will drastically reduce the time needed, guarantee total respect for the surfaces treated, fully record the cleaning cycle, and collect the material resulting from the cleaning operation in the keelcrab-bag.

Frequently asked questions

The keelcrab drone is designed to have a cleaning capability classifiable as a “routine maintenance” of your hull respecting the surfaces, chemicals and technical elements on the living work. Since there is no scale (benchmark) with regard to the ability to abrade and remove dirt that has taken root to a boat hull, we start with the mechanical concept that the drone exerts 3.5 kg of thrust (when fully submerged) toward the hull surface and moves in counter-rotation (counter-rotation effect) a cylindrical inset brush body made of nylon (of 2 different weights) or corrugated stainless steel. Micrometric tests (pre and post robot passage) in a simulated environment (including with wastewater analysis) and practical feedback led us to obtain certification from A.N.C.C.P and to demonstrate that: complying with the starting condition of “perfectly clean boat” and “painted” with new antifouling, a hull is “still on target” (still workable i.e., cleanable by the keelcrab drone) even after a period of 6 to 8 months of complete stationing in port waters.

In the case of paints that are even partially water-soluble (self-sanding) if navigation was not possible, in order to avoid micrometer reduction of antifouling when using the drone, use is constrained to the removal of the central brush body, leaving the dual tasks of keeping the machine in adherence and sucking up silt algae or vegetation to the suction capacity alone. The proportion between suction capacity in kg and robot feed rate, demonstrates how using keelcrab without its brush body simulates slow sailing (less than 3 knots) by stimulating the paint’s natural chemical self-cleaning process.

All consumable and non-consumable items (thus covered or not covered by warranty) are designed with the logic of “do by yourself” allowing maximum freedom and autonomy over drone assistance. Assembly and disassembly operations of individual marinized components are therefore executable by anyone and without the use of special technical equipment. In all cases, replacement or intervention operations are supported by dedicated video tutorials and you will be able to find them: in the restricted area of our website, by sending a w.up to +39 327 029 5197 with a request to open a service ticket or a specific request for the consumable component you intend to replace or by sending an email to ufficiotecnico@keelcrab.com with the subject line “video tutorial for technical assistance” specifying the consumable technical component you intend to replace. One of our assigned technicians will follow up with you for quick troubleshooting.

The entire Keelcrab line is entirely designed and manufactured in Italy (100% made in italy) in our production facility in the province of Como, and the average delivery time is about 2 weeks from order.

  • 12-meter boat: 1 hour
  • 16-meter boat: 1 hour and 30 minutes
  • 18-meter boat: 2 hours
All consumables are:
  • Replaceable in total autonomy
  • Available h48 directly from us
  • Variable durations from a minimum of 50 hours to a maximum of 500 hours of use.
There are no other variable costs of maintaining your device in efficiency over the years.

Abundant rinsing with fresh water after each use and sheltering in a dry, sheltered place.

Keelcrab is maintained in perfect adherence to the hull thanks to a major suction effect generated by a powerful marinized pump motor by removing and sucking up algae or vegetation that typically builds up on the live work of boats during periods of dwellings in closed waters. The Keelcrab drone is capable of cleaning (once quickly mastered in piloting operations) up to the 95/97% of the surface area of a displacement hull of a sailboat that exhibits characteristics of shapes and geometries classifiable as “standard” in the 10/24 meter range and 85/87% of a planing or semi-planing hull of a motorboat that exhibits characteristics of shapes and geometries classifiable as “standard” In the range 10/ 24 meters.

Vertical motorized brush is the last upgrade of summer 2022 developed by R&D department of Aeffe ltd: this solution improves hull maintennace and cleaning performance.
