Smartgyro has detailed the installation of its latest-generation SG40 gyro stabiliser aboard the new Bluegame BG64 ahead of the 20-metre yacht’s Cannes world premiere. During commissioning and sea trials, the company reports that the system achieved up to 86% roll reduction.
SG40 becomes part of the BG64 comfort package
The BG64 sits between Bluegame’s BG54 and BG74 and combines an open connection to the sea with accommodation and an upper deck designed for longer cruising. Smartgyro’s SG40 was selected to reduce roll both underway and at anchor, adding active comfort to the yacht’s broader layout and performance package.
Gyro stabilisation is particularly attractive on yachts in this size range because owners increasingly expect day-boat openness without accepting uncomfortable movement at rest. The stabiliser adds weight and electrical demand, but it can substantially change how social spaces are used in exposed anchorages.
Commissioning produced the headline figure
Smartgyro says sea trials recorded up to 86% roll reduction with the SG40 operating aboard the BG64. Roll-reduction percentages depend on sea state, loading, test method and operating conditions, so the figure should be read as a commissioning result rather than a universal guarantee.
Even with that qualification, the result gives buyers a useful indication of the system’s effect on this specific hull rather than relying only on generic product data. Yacht-specific test results are valuable because gyro performance depends heavily on vessel displacement, roll period and installation.
The SG40 itself has been substantially updated
Smartgyro completed an upgrade programme for the SG40 in 2025, revising performance, power consumption, maintenance access and serviceability while retaining a compact installation footprint. The manufacturer says the current generation draws on more than a decade of operational experience and owner feedback.
Service access is an important ownership issue because gyro systems contain high-speed rotating machinery that must remain inspectable throughout their life. Smartgyro’s modular philosophy is designed around onboard maintenance rather than requiring major structural removal when components need attention.
Bluegame and Smartgyro deepen an existing relationship
The BG64 is not the first Bluegame to use Smartgyro equipment, with installations already spanning models including the BG54, BGX63 and BGM75 multihull project. The repeated selection suggests stabilisation is becoming part of the builder’s standard engineering conversation rather than an isolated owner option.
For BG64 buyers, the important question is how the system performs across real cruising conditions after the launch period. The commissioning result is encouraging, and the yacht now provides another reference installation for owners assessing gyro stabilisation on a sub-24-metre performance cruiser.
