Smartgyro has completed an R&D programme to develop a tailored gyro solution for multihull vessels — starting with the Bluegame BGM75.
The project, which began in 2024, aimed to overcome the challenges of stabilising power catamarans.
The Bluegame BGM75 presented Smartgyro’s R&D team with challenges compared to single-hull designs.
The BGM75 has been designed with a seamless lower deck and a full beam owner cabin which limited the available installation points for a gyro stabiliser.
In addition, Smartgyro points out that the fundamental distinction between monohulls and multihulls lies in their motion dynamics with waves impacting each hull at different moments and one hull often being immersed at a different level than the other.
Although the solution was tailored for the BGM75, the methodology can be adapted to other multihull configurations.

Consequently, a catamaran of comparable size requires greater stabilisation forces, applied with concise timing with software modifications applied to a standard gyroscopic stabiliser which otherwise would not effectively with the specific motion of a multihull.
To provide stabilisation to the BGM75, two SG80 units were installed, one in each hull.
In addition, a custom algorithm was developed to control force output with precise timing.
Software modifications also enabled the gyros to deliver higher-than-normal torque, but only when required by the vessel’s dynamic motion.
Alongside onshore development, the team carried out on-water development using adjustable ballast to simulate different behaviors on the BGM75 test hull.
Adapting methodology for different configurations
Sea trials were conducted using different algorithmic setups, with continuous data collection., particularly monitoring vessel behaviour in a variety of conditions.
“As a team, we take great satisfaction working closely with OEMs to address complex challenges,” explained Fabrizio Stifani, R&D manager at Smartgyro.
“This project not only enhanced onboard comfort, but also helped evolve our product intelligence.
“Although the solution was tailored for the BGM75, the methodology can be adapted to other multihull configurations.”
The Bluegame BGM75 featuring Smartgyro’s stabilisation will be on show at the 2025 Fort Lauderdale International Boat Show.
