STABILISATION
SMARTGYRO The benefits of Smartgyro’s seamless stabilisation installation and maintenance can now be experienced by even more of the superyacht market, with the introduction of two new models of gyroscopic stabilisers, the SG120 and SG150 expanding the range to now include yachts over 95’. Owners, guests, and crew can all enjoy more time on the water, thanks to the innovative modular mechanical design unique to Smartgyro, resulting in less downtime and more yacht time, whatever the sea conditions. The range of gyroscopic stabilisers, offers advanced control electronics, braking systems, liquid cooling, and the flywheel within a vacuum housing, efficiently maximising the roll reduction and performance for uninterrupted comfort onboard.

“Similarly, management of the vacuum inside the sphere itself is another point of difference between us and others on the market. Air friction at 10,000 rpm is very high, and some use a high degree of vacuum to compensate for a less powerful, or less efficient electric motors. Unlike our motors which are directly liquid cooled, others are not and heat can sometimes get introduced into the sphere.
“The design of Smartgyro is different, and inside the ball everything is cooled with glycol, including the motor and bearing pack, so it is not necessary to use helium or other gases. Furthermore, repairs to leaks on spheres with anything other than air inside the vacuum are often complicated, and not possible to be carried out onboard. Over time, therefore, the vacuum itself gets depleted and the gyro gradually becomes less and less effective.”
It’s just a theory, but when it comes to retrofit on used boats, it appears that gyros get the lion’s share of that market.
VEEM’s Sales Manager, Dan Fisher, would seem to agree, when he told me: “VEEM Marine Gyrostabilizers are very well suited to retrofit applications on account of their self-contained, compact configuration. Unlike other stabilisation systems, gyros do not rely on drag-inducing external hull appendages and are all-in-one units that do not require multiple points of installation and hull penetrations.”
Certainly, by looking at their six-model line-up,for yachts from 65ft (20m) upwards, I would agree with Dan that each model looks nothing less than ‘bomb-proof’ in appearance, with everything encapsulated in a high strength aluminium vacuum chamber and support frame, with equally sturdy looking mounts that transfer the stabilising torque forces back into the vessel. Dan adds: “Depending upon access, VEEM Marine gyros can even be installed without drydocking. This simplicity also allows for simplified service and maintenance because all of our units are

fully maintainable in the vessel. You can even carry out the 10 year/35,000 hour overhaul with the gyro in the vessel while still afloat.”
Operator feedback, combined with data collected from units in service is proving vital for improving the product and enhancing the overall experience.
VEEM, for example, has recently examined the condition of bearings and other wearing components in its longest serving machines. This valuable intelligence has resulted in new operating guidelines and preventative maintenance intervals, that will extend the time between component replacement and reduce the overall cost of ownership.
It’s perhaps an obvious thing to say, but working with designers and yards as early as possible, to optimise installation configuration and preserve the recommended service access pays off in the long run.
