Thank you to everyone for posting your comments on our system, your feedback is very helpful.
To address one or two comments in particular;
1. The power consumption of the system should not be in issue assuming most vessels are equipped with the correctly sized generator. The maximum consumption of the system in underway mode will be 3KW with the average consumption at 2KW, this is very much dependent on sea conditions. If a vessel does not have a sufficiently sized generator it would need to be upgraded at the time of the installation of our system. Compared to installing hydraulically operated fins, the simple upgrade of the generator would be far more straight forward. Both the Chief Designer of the equipment, Theo Koop, and ourselves have many years experience designing and manufacturing hydraulic fin systems for the Super Yacht market and fully understand the complexity and inherent problems of such installations both in terms of installation and ongoing servicing. This is why we concentrated our efforts on producing a fully electronic retractable system with the added benefit of producing far greater amounts of lift force required to stabilize a boat when it most requires stabilization i.e. at zero speed, slow speeds and cruising.
2. With regard to the comment regarding the demonstration videos on our website RotorSwing UK
- we completely agree that the best way to showcase the performance of the equipment will be to produce a video of vessels at sea in real life conditions and this is our intention. The videos currently on the site are very much "early days" videos as this system is brand new to the market. We have concentrated our efforts on perfecting the system performance and the video you see on the site was put together in order to have something on the site whilst we work on filming and producing the new video. The "forced roll" video gives an idea of the amount of roll that can be eliminated by the system when operated normally. The amount of roll that can be induced by the system can also be eliminated. In early 2014 you will see our new video added to the site and so please keep checking back. I will post a link when this is available.
3. To clarify how and why this system works so well please allow me to give a brief summary and history.
Having spent the past 30 years designing and manufacturing hydraulic fin systems, Theo Koop has earned a reputation as one of the world leaders in yacht stabilization. Formerly - Theo was behind the well known brand KoopNautic and, having sold this company to Naiad, Theo became part of the team at Quantum Stabilizers who are widely regarded as the market leader in Super Yacht stabilization. When Theo joined Quantum the first ever Zero Speed Stabilization system was designed and installed which changed the way many super yachts have operated for the past 15 years. Quantum has gone on to supply almost 1000 of these systems worldwide on a range of Super/Mega Yachts, military and commercial vessels. Quantum currently holds around 85% of the market share.
In 2008 Quantum was engaged to design and manufacture a system for the worlds largest privately owned Mega Yacht at the time - MY ECLIPSE. Due to the size of fins required for this 160 meter project Theo and Quantum designed and manufactured the MagLift Stabilizer which in essence is a hydraulic version of the RotorSwing system.
Both the MagLift and RotorSwing system employ the exact same principal in order to produce lift forces required to stabilize a vessel - The MagNus Effect. By rotating a cylinder in water - an upward or downward lift force is produced in a similar way to when a tennis ball is hit with top spin or back spin. The amount of lift force that can be produced by the RotorSwing system is far greater than the comparable fin size. The rotor is also installed at a much more efficient angle to the water line resulting in only a 5% loss of lift compared to a typical fin installation which looses approximately 35% of it lift due to its orientation. The result of this calculation on a typical vessel is that the RotorSwing system will be approximately 3 times as effective as fins. A more in depth calculation of this can be found on our website at RotorSwing – A Comparison Calculation Between the RotorSwing and Fin Stabilizers
When you consider the fact that the RotorSwing system is retractable under the hull to reduce drag at higher speeds where the system is not required as well as being electronically operated the system has major benefits over any other system on the market. We are very confident of this based on our experience and are keen to demonstrate this to the market.
