Green solution

The KeelCrab robot removes the layer of vegetation without affecting your antifouling but rather, prolonging its lifespan.

The waste material is is collected inside the filter bag (optional).

Efficiency of antifouling

Maintenance and prevention improve the efficiency and durability of your antifouling.

Numerous tests have shown that constant removal of the first layer of vegetation (3/5 mm) causes an important extension of antifouling life, which results in the 'impossibility of the formation of "dog teeth" (barnacles) and reduced hauling in the long run.

Always top navigation performance and low fuel consumption

Reduction of extraordinary hull cleaning operations in the medium term to ensure high levels of sailing performance of the boat at all times, maximizing efficiency of the delicate performance/consumption relationship.

Frequently asked questions

Green Keel Pack is recommended for yacht or pleasure boat owners or shipowners in general who want to directly and independently manage the maintenance of their hulls by espousing green solutions that aim to reduce haulage in the long run, to make the consumption-performance relationship more efficient in total respect of their hull and always in total autonomy.

Ultracrab ALWAYS (as much as possible), Keelcrab at least bimonthly (in the case of non-water-soluble chemicals classifiable as fixed matrices) or at least quarterly (in the case of water-soluble chemicals classifiable as self-smoothing); the main benefits occur especially during long winter (or worse summer due to higher temperatures) boat stops in ports, periods when stationing produces greater proliferation.

  • Speed of use and cleaning
  • Performance always at the TOP
  • Autonomy in hull maintenance operations
  • Reduced fuel consumption
  • Reduction of wingings in the medium term
  • Green solution (decreased consumption and decreased need for antifouling with biocide in the medium term)
