Smartgyro Advances Multihull Stabilization with Tailored R&D Approach

A steadfast focus on precision engineering and real-world testing delivers unprecedented results, strengthening Smartgyro’s innovation pipeline.

Smartgyro, a global leader in marine stabilization technology, has completed an advanced R&D program to develop a tailored gyro solution for multihull vessels — beginning with the Bluegame BGM75. This highly specialized project, originally launched in 2024, aimed to overcome the challenges of stabilizing a new class of luxury power catamarans. The results are a testament to Smartgyro’s engineering capabilities, agile development process, and commitment to innovation.

Stabilizing Multihulls vs. Monohulls  

From the outset, this project set an ambitious goal of surpassing the comfort levels traditionally associated with stabilized monohulls.

The Bluegame BGM75 presented Smartgyro’s R&D team with unique challenges compared to single-hull designs.  The closer proximity of the two hulls enabled Bluegame a seamless lower deck and a full beam owner cabin, but it also limited the available installation points for a gyro stabilizer, making the precision of the algorithmic solution even more critical.  

The fundamental distinction between monohulls and multihulls lies in their motion dynamics. In a catamaran, the two hulls do not roll in unison, as waves impact each hull at slightly different moments. This results in one hull often being immersed at a different level than the other, creating an asynchronous motion response.  Consequently, a catamaran of comparable size requires greater stabilization forces, applied with concise timing.

For more insight into why catamarans benefit from gyro stabilization, see our recent blog: Why Stabilization on Catamarans Matters.

A Tailored Engineering Solution

A standard gyroscopic stabilizer, without software adaptation, does not synchronize effectively with the specific motion of a multihull.  Without dedicated software modifications, the system would not provide effective stabilization.  

To meet the challenge, Smartgyro’s engineers installed two SG80 units, one in each hull of the BGM75, and developed a custom algorithm to control force output with precise timing. Software modifications enabled the gyros to deliver higher-than-normal torque, but only when required by the vessel’s dynamic motion — a critical factor for effective stabilization in asymmetric sea conditions.

From Theory to Sea Trials

Alongside extensive onshore development, the team followed a rigorous and articulate testing program on the open seas. Adjustable ballast was used to simulate different behaviors on the BGM75 test hull, replicating a range of metacentric height variations. Multiple sea trials were conducted using different algorithmic setups, with continuous data collection. These insights drove iterative refinements, culminating in a performance level that met the high expectations of both Bluegame and Smartgyro.

Parameters monitored included:

• Dynamic vessel behaviour. Considering the feasibility and safety of berthing a vessel across a variety of conditions.
• Sea state data. Including wave height and wave period, precisely recorded with technical instrumentation.  
  
  

Strengthening Smartgyro’s Innovation Pipeline

“As a team, we take great satisfaction working closely with OEMs to address complex challenges.” said 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. It proves that Smartgyro can engineer to specification, and deliver results.”

The insights gained through this extensive testing enabled Smartgyro’s R&D team to further develop its predictive algorithms and refine stabilization logic. The learnings have already contributed to firmware updates across the Smartgyro range, reinforcing system performance, design integration, and onboard comfort.

The program also confirmed Smartgyro’s ability to deliver flexible, high-performance solutions while maintaining core advantages such as onboard serviceability and modular installation — benefits increasingly valued by both builders and operators.
