Frequently asked questions
What is it capable of cleaning? Does its use remove antifouling paints?
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.
How is technical assistance organized?
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.
Production and delivery time?
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.
Average cleaning times?
- 12-meter boat: 1 hour
- 16-meter boat: 1 hour and 30 minutes
- 18-meter boat: 2 hours
Consumable life or other variable maintenance costs?
- 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.
Does it require special maintenance?
Abundant rinsing with fresh water after each use and sheltering in a dry, sheltered place.
How does Keelcrab stand in adhesion to the hull? Is it more suitable for planing boat hulls (motor boats) or displacement boat hulls (sailing boats)?
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.
What is Vertical motorized brush?
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.
