and easy to locate electric direct-drive motor, at speeds above 12 knots the roll-damping effect becomes negligible, and the product sensibly retracts.
Last of all, DMS Universal is an up-to-date operating system that can be swopped in place of a malfunctioning, or parts-redundant control box, to prolong and extend the working life of fins and actuators and so forth, as opposed to scrapping and replacing expensive hardware that otherwise had nothing wrong with it in the first place. The potential for cost-saving here is huge, and I think DMS Holland should be commended for having this kind of money-saving attitude.
But with all that’s been said about alternative stabilisation technology, it’s gyros that have been around the longest and the technology shows little sign of plateauing anytime soon. Credit where credit is due I say.
Early criticism from competitors levelled at the cost, the size and general inconvenience of gyros taking up large amounts of space inside a hull, have largely diminished. Manufacturers have bounced back with a vengeance, with new gyro systems that are not only smaller, but are quicker, easier and less expensive to maintain.
Based in La Spezia, Italy, take Smartgyro, for instance, who’s modular gyro units can be serviced, maintained and assembled directly inside the boat.
Incorporating the sphere with flywheel and base frame negates the need for the gyro to be shipped back to the factory for servicing. Seamless installation and onboard maintenance mean vessel downtime is reduced. New design opportunities are created for builders, and there is increased potential for installation in vessels with small or restricted access spaces.
The range includes systems for a variety of vessels in the 30 to 80ft range. With further units under development, the SG series now consists of the SG20 (45 to 55ft), SG40 (50 to 60ft), SG60 (55 to 65ft) and SG80 (over 60ft). Average power
consumption is said to be considerably lower than for competitor units, suggesting that other products might require a larger generator for the same level of roll-reduction.
Even down to the smallest detail, such as having entirely recyclable cardboard packaging and reusable wooden crates, it’s clear that efficiency and sustainability are key considerations for Smartgyro and I commend any company with that kind of positive attitude. With a six-model gyro range aimed squarely at yachts and megayachts in the 20m plus category, VEEM Marine from Australia has focussed on making it as easy as possible for customers, from all over the world, to buy their product.
What exactly do I mean by that? Well, even though these are large and complex products, VEEM Marine are still able to offer a lot of product ‘off the shelf’ and ex stock.
Brett Silich, Global Commercial Manager, told us “Clients can purchase our product often with very short lead times for refit projects, and we saw this became a real selling point last year, for owners having quickly made a decision they would like stabilisation onboard. Depending upon the installation method, docking the vessel is not always essential and often this type of installation can be done alongside the quay.”
Brett is convinced that in the often heated debate over ‘gyros versus fins’, the stabilisation of a vessel at rest (when owners desire the best performance for using toys, for swimming, diving and even for pilots trying to land or take off in helicopters), is superior with the correctly paired gyro(s), over all other stabilisation means.
Brett feels gyros offer greater options for designers and naval architects, in particular with the trend for explorer-style yachts, transiting areas with the potential for ice, that otherwise would not be suitable cruising ground for external appendages, such as fins. “Gyros are completely contained within the hull,” says Brett, “and for environmentally conscious owners pursuing DNV Silent or RINA Dolphin underwater noise classifications, gyros have lower noise and vibration levels inside and out.”
