At JG Clean, we use the state-of-the-art Keelcrab underwater robot to deliver efficient, eco-friendly hull maintenance — all without lifting your boat out of the water. Designed and built in Italy, the Keelcrab is a compact, powerful ROV that gently but effectively removes algae, marine growth, and fouling, helping to preserve your boat’s antifouling paint and keep you sailing smoothly.
Before we start, our team assesses your hull’s condition to tailor the cleaning to your boat’s size, hull type, and fouling level. This ensures we use the right approach for the best results.
Our trained operator deploys the Keelcrab directly in the water — no need for drydocking or lifting. The robot uses its powerful suction system to cling safely to your hull, while its motorized, cushioned counter-rotating brushes remove surface growth without damaging your antifouling coating.
While cleaning, we monitor the process through a high-resolution underwater camera, allowing us to inspect the hull thoroughly and guarantee full coverage. After the clean, we share high-resolution footage of the process so you can review the results with complete transparency and peace of mind.
All removed algae and marine growth are vacuumed into a fine mesh bag, preventing debris from reattaching to the hull or polluting the water. The collected material is biodegradable and often reused as nutrient-rich compost, supporting our commitment to eco-friendly maintenance.
Our ANCCP-certified brushes maintain the integrity of hard matrix antifouling coatings, extending their lifespan by regularly removing early-stage growth.
Cleaning speeds up to 6 m² per minute mean less time tied up in maintenance and more time enjoying the water.
No chemicals or detergents are used, and all waste is collected responsibly.
The robot maneuvers easily on all hull types and sizes (up to 24 meters), including displacement and planing hulls.
Operated via joystick for precise maneuvering, with real-time video feedback to monitor the inspection. All footage is recorded in high resolution and shared with you afterward for detailed review and documentation.
By choosing JG Clean’s Keelcrab service, you’re opting for a hassle-free, safe, and thorough underwater hull clean that protects your investment, reduces fuel consumption, and keeps your boat performing at its best.
