AntiRoll – ‘Care for Comfort, Care for the Ocean’
Roll damping system for yachts in excess of 30 metres
A superyacht is synonymous with comfort. To achieve the absolute highest level in on board comfort, a yacht must lie still in the water and not rock to and fro. Owners and guests want to be able to enjoy all luxuries on and around the yacht, from the jacuzzi on the sun deck to a to Michelin rated dinner, without any disruptions.
Stabilizers are installed on almost all superyachts. Stabilizers reduce the non-desirable rolling of a yacht and increase onboard comfort. In turn, this reduces sea sickness and should the yacht come up against bad weather and conditions, the stabilizers improve safety on board. Most superyachts are fitted with a so-called ‘zero speed’ system. There are also systems on the market that stabilize the roll both during sailing and when moored. The performance of these systems are not truly optimal as a compromise has to be made between the sailing and mooring performance.
Thanks to its unique, dual-axis fin stabilizer, which rotates whilst sailing and flaps at anchor, AntiRoll provides stabilization both underway and at zerospeed without any compromise of performance in either circumstance.
The curved, high-aspect ratio fin significantly reduces the drag by between 50 and 75 percent whilst sailing which in turn has a positive impact on the fuel consumption. In addition, with the fin flapping at zerospeed as opposed to rotating, a greater lifting force is generated providing a more stable platform. Of particular interest for sail yachts, the fin is also retractable and can be partly folded back in to the hull. This leaves only minor resistance whilst sailing – a feature welcomed by sailing enthusiasts and which solves well known problems related to non-retractable fins. AntiRoll uses an innovative hybrid drive system resulting in relatively low power requirements.
A combination of towing tests, model tests and experts have confirmed that the AntiRoll system will deliver better performance, both in terms of stabilization and resistance through the water. This low resistance through the water makes AntiRoll ‘greener’ than any other system.
AntiRoll is developed in collaboration with well known parties such as MARIN, TNO and TU Delft and patented.
