A revolutionary generation
of fin stabilizers
Only a fin stabilizer system can handle both cruising and at-anchor well. On a typical fin stabilizer system optimized for at-anchor stabilization, the fin size is larger than the fin used for underway only. Larger fins provide more stabilization force, but also create more drag which equals higher fuel consumption, especially at higher speeds, an important point for most boat owners. Larger fins also means that the internal components grow in size, making it difficult to install them in an optimal position.
Some stabilizers end up with negative side-effects like causing yaw (steering effects) and sway (side-ways movements). These side effects force owners and designers to compromise stabilization for efficiency. With the introduction of the Vector Fin™ and Side-Power's range of compact actuators, there is no need to compromise. Now you can have it all; speed, efficiency and a stable boat.
A simple solution to a complex problem
The Side-Power Vector Fin™ stabilizers improve the roll reduction efficiency by some 50% in at-anchor mode, and 30% while underway, while at the same time reducing undesired yaw and sway motions caused by active fins. The huge benefits both for efficiency and reduced side-effects make them particularly ideal for any type of vessel from today’s modern, fast cruisers to trawler style vessels with lower speed ranges.
Each has their own challenges: Lighter, fast boats are more prone to sway while at anchor. (This is where the fins physically push the boat side to side rather than reducing the roll.) Trawler style boats require bigger fins and become prone to yaw. (The fins steer the boat as they actuate causing wear and tear on the steering and stabilizer systems and reducing the efficiency of the hull.) In each case, vector fins redirect this wasted energy to better stabilize the boat and minimize these ill effects.
