The satellite anchor: stability and respect for the sea
The goal of the project is clear: to create a device capable of keeping a boat practically stationary anywhere at sea, regardless of seabed type or depth. Today, recreational sailors rely solely on the traditional anchor, which cannot fully eliminate movements caused by currents, or on systems that facilitate mooring maneuvers via joystick.
Maintaining a stable position at sea remains a challenge: the traditional anchor requires a scope at least three times the depth, performs poorly on sandy seabeds (“plow effect”), and can get caught on rocky bottoms, often requiring complex interventions to free it. The satellite anchor revolutionizes this concept: the reference point is no longer the seabed, but the satellite. Thanks to GPS, the device maintains the boat in the desired position.
The system, resembling a buoy that is deployed at the start of the stop, consists of a satellite antenna that continuously detects the position, a board that stores latitude and longitude data, and a second, more advanced board that converts this information into commands for the electric thruster, allowing automatic adjustments in power and direction. The thruster is powered by photovoltaic cells with a backup battery, ensuring a completely eco- friendly operation.
Early prototypes revealed some stability issues, which are currently being refined. Development focuses on the anchor’s final design, lightweight and waterproof materials, and reliable thruster operation. The electronic boards record position data every 5 seconds and convert it into commands for the electric motor, powered by photovoltaic cells, ensuring precise and autonomous performance. Beyond stability, the satellite anchor delivers a tangible environmental benefit.
Traditional anchors damage sandy and rocky seabeds and require frequent motor adjustments to maintain position, producing harmful emissions and discharging heated cooling water into the sea: these effects become significant considering the high number of boats at sea. The satellite anchor eliminates these issues, protecting marine flora and fauna while reducing pollution. The concept originates from the analogy with a GPS navigation system: changing the reference from the seabed to the GPS enables precise and secure station-keeping.
Recreational sailors can enjoy freedom, simplicity, and safety without compromising the environment they cherish. Even though initial prototypes showed minor stability challenges, they demonstrated effective interaction with the GPS system and the ability to maintain position accurately. The satellite anchor is not just a technological innovation but a revolution for sea enthusiasts. Deployed at the start of the stop, it integrates a satellite antenna that records the position every 5 seconds, a data storage board, and a second board that translates the data into commands for the electric thruster, adjusting power and direction.
It features dual control for activation and deployment, and the motor is powered by photovoltaic cells with a backup battery. Three key values—ease of use, freedom of movement, and environmental protection—make it the definitive alternative to the traditional anchor.
