Can I use the drone cable to transport or guide Keelcrab? Not exactly. It is possible to move Keelcrab and pull it carefully by the cable only when the drone is in the water. Instead, either you have to take it out the water or you have to immerse it, we strongly advice to use the handle (standard KIT)
How to collect the vegetation removed by Keelcrab? In the claw pack we provide the Keelcrab bag kit that is able to recover part of the vegetation removed through a nylon filter bag. In this way, you can avoid that part of the vegetation removed is able to stick again on the hull’s surface.
What’s the voltage? 220 VOLT or 110 VOLT (USA standard) , converted in low voltage 48v
What’s its power consumption? Maximum is 250 watt/hour and average consumption is 200 Watt/hour
What’s the standard length of the drone power cable? Its length is 20 meters – Is the power cable reinforced ? Yes, it is reinforced with Kevlar (120Kg traction)
What’s the standard length of remote control cable? The remote control cable length is 5 Meters.
What’s the Led power? The Led power is 200 Lumen
How deep could it be used? The maximum depth is 10 meters.
What is Keelcrab drone able to remove? Keelcrab cleaning function is set to make the drone able to remove algae and vegetation; numerous tests have proven its effectiveness even on boats moored in port waters since 6-12 months
Does Keelcrab remove mussels or barnacles ? If not why ? It doesn’t for valid reasons. First of all, in case such organisms grow up on hull’s surface, it could mean two things: either the anti- fouling paint used is not suitable for the waters where the boat is moored or it’s been too long since the last time the anti-fouling has been drafted on the hull’s surface. Secondly, our experience has taught us that their removal on the water could be very dangerous for the safety of the hull and for its life cycle. Such organisms normally stick so hardly on the hull that their forcible removal through a large abrasion, is be able to provoke for sure the detachment of the paintings and in the worst cases this operation could compromise the physical integrity of gel coat causing as a result problems of moisture infiltration and osmosis. In such cases there’s no other solution but to take the boat out of the water and to let the dockyard make the standard cleaning cycle usually performer by raising the boat with crane.
Can I potentially clean all the hull’s surface using Keelcrab? In terms of percentage, keelcrab is able to clean 80/90% of the hull of a sail boat and motor boat with planing hull by 40 feet and up leaving to the shipowner or professionals the shafts, propellers, rudders and corners
How many times do I need to use Keelcrab? It depends from several factors such as the temperature and the type of water, presence of fresh water tributaries and seasonality. However, our experience allows us to say that if water temperature exceeds 22/23 degrees it is advisable to use it even once a month;
Does Keelcrab remove anti fouling paint? Keelcrab use soft brush and therefore does not remove antifouling paint
Is it possible to order an extension of the cable? Yes of course, it possible to customize the length of both the drone cable either the remote control cable sending an email to email@example.com.
Can I replace the brush myself? The brushes are easy and fast to replace with an Allen key n.4 . Tutorial are available sending an email to firstname.lastname@example.org with object “tutorial brush”
