“Comfort and enjoyment at sea is greatly enhanced by a quiet “vibration-free” environment, which also reduces levels of fatigue and boosts alertness. To achieve this, Bering utilizes the latest acoustic technologies and components to include Seatorque roller bearing shaft systems.”
“Our yachts are incredibly quiet,” explains Mikhaillov. “As a large majority of our customers are recreational users, the length of journey at sea can be considerably long. Therefore, the added feature of vibration-free, quiet cruising is a key sales angle for our buyers.”
“The vessel’s light weight, propeller design and shaft system all add together to make a huge difference,” said Chavez. “In all my years on the water, I have never witnessed a vessel this size with a comparable power package to cruise at this speed. Thanks to Seatorque’s enclosed shaft system, the vessel achieved maximum horsepower, experienced zero shaft noise and vibration, and produced very little wake.”
“I have to give Seatorque Control Systems a plug, great system. One of the big problems as to noise on a boat is the shaft noise and also vibration. This system is one of the quietest and vibration free systems I have ever experienced… on any boat.”
“We’ll probably never build another boat without it (Seatorque)”.
New Installation: 72’ F&S Boatworks “Bandolera”:
The initial sea trials of LAMBETH , the PLA’s (Port of London Authority) new launch built at Alnmaritec and now forming the first of class of their “Wave Guardian” class of patrol boats , have been very successful. We’re currently testing and tuning all the navigation and operational equipment.
With the propellers designed by Newcastle University and H4 Marine supplied Seatorque’s oil-lubricated stern shafts, we are achieving the 2,600 rpm maximum revolutions of the engines …..The Twin-Disc electronic engine/gearbox controls make the vessel very manoeuvrable with safety, in confined waterways, and the Seatorque stern-gear is a great success in reducing noise, vibration and transmission losses. At Professor Mehmet Atlar’s modelling and tank testing of the optimised hull form, he (conservatively) predicted 18.5 knots with 2 x 200 SHP @ 2,600 engine rpm, for a 10.6 tonne completed vessel.
With the propeller optimised and with the slippery Intersleek 900 silicone-based anti-fouling, we are achieving a mean speed of 21.0 knots in the vessel in its finished state (11.0 tonnes)… I am convinced that the successful power delivery is also a result of the reduced transmission losses from the oil-lubricated stern gear.
So we’re delighted with the performance and will be showing the vessel off, at Seawork, to provide a platform for all equipment contributors.
Thanks for your contribution to this project. We have a great boat, in which everyone can be pleased!
“Marex started with the Seatorque system on our new project Marex 370 Aft Cabin Cruiser. In an aft cabin boat, the engine has to be centre placed with the risk of sound and vibration disturbance.We needed a silent system. We were very surprised how little vibration and sound the Seatorque system produced.It was simply exactly what we wanted.The higher efficiency in speed was a very big bonus and has become another key selling point for the Marex 370.The system helped us to win the “European powerboat of the year 2009”
