Roll Damping Videos

These short videos can provide you with real life roll damping experiences from RotorSwing. Some videos also give some information as to how this yacht stabilizer system functions. If you want to witness the RotorSwing roll damping system for yourself, we also offer test rides on several yachts, both on displacement yachts and on GRP vessels.

RotorSwing 140 Multi roll yacht stabiliser

This Fairline Squadron 55 is fitted with a RotorSwing 140 Multi, which is the ZeroSpeed version. The sea trial was performed while battling a 2.5 meter beam sea during wind-force 5. Since the natural roll period of this yacht is 3 seconds, the yacht stabilisers have to work fast and hard. RotorSwing has developed new technology that can cope with this kind of fast roll on a GRP ship. It is currently available under its code name 140 Multi. The performance of the yacht stabiliser not only performed outstanding at half sea but also during fast turns and following sea. Following sea is especially difficult to control, but RotorSwing has conquered this challenge.


Roll damping in wind-force 8

This short video shows the power of the RotorSwing roll damping system. An independent party was onboard this 50′ yacht to check out the effectiveness of our roll damping system. Since it was wind-force 8, filming became uncomfortable without the RotorSwing enabled! Yacht stabilizers come in many different shapes and forms but RotorSwing is highly effective for yachts up to 35 meters (115 feet). These rotors start working even at 3 knots. This is not the case with fin stabilizers. They are simply one of the most powerful roll damping systems on the market.


Roll damping while cruising and at anchor

RotorSwing Marine is performing many tests and measurements to objectively be able to improve on it’s own roll damping system. The video shows both functions of this yacht stabilizer; roll damping while cruising (underway) and roll damping while idling or at anchor (zerospeed). We also tested the natural “roll out” time of this rather heavy 15 meter steel yacht. This was done while inverting the gyro signal to make the displacement vessel roll. After the yacht is rolling profoundly, we switch the gyro signal back to roll damping. In less than 2 periods, the vessel is stable!


Forced Roll: Switching the gyro signal

RotorSwing stabilizers have a “Forced Roll” function to demonstrate its powerful effect when there are no waves. This forced roll mode is basically a testing mode for the RotorSwing to show the efficiency in roll damping. This Linssen displacement vessel is fitted with the Underway roll damping system. After the yacht has been placed in a large roll motion, the captain switches the system to roll damping. The yacht will almost instantly diminish the roll to a minimum. Even on larger displacement vessels of significant weight, the RotorSwing yacht stabilizer works superb!


Anatomy of the Underway roll damping system

This yacht stabilizer by RotorSwing Marine is the Underway version. This video shows the main anatomical structures. Only a small area within the engine room  is required to install the system.

The yacht stabilizer is also very flexible in terms of installation placement (anywhere between aft or midships). This is due to the fact that the RotorSwing yacht stabilizer is installed almost horizontally and therefore eliminates steering effects. The belt drive has been proven to be successful for many years in the automotive industry.
