What do stabilizers do?
Less Overall Fuel Consumption
Stabilizer systems have been around for a long time, but typically only used on larger passenger ships and super yachts. The dramatically increased comfort and usability of any boat, have made owners of also smaller leisure vessels wish for this. When installing a high performing stabilization system onboard, you benefit from:
More use of the boat as you can go out in more weather conditions.
People that easily get seasick can now enjoy boating.
Less wear and tear of the boat as you do not have to always head into or away from larger waves to avoid the uncomfortable rolling motion.
Increased Comfort on Board
Reduced risk of accidents caused by unexpected boat roll.
Increased crew awareness by less fatigue and discomfort.
Increased Second Hand Boat Value
Surely, the boat will be a lot more attractive on the second hand market, boasting a system that allows people which might be prone to seasickness to reconsider their ability to enjoy the sea, and thereby adding a whole new range of potential buyers.
Increased Safety on Board
While adding fins (or other stabilizer types) most systems will increase the fuel consumption a little at the same speed, fins by direct drag in the water, and gyros by adding weight. However, our claim is that the overall fuel consumption will be reduced because with stabilizers, you can take the direct route to where you wish to go, even in rough conditions. You can also choose a more fuel efficient speed, with the waves from the side, while still being comfortable (modern cruisers have less roll at higher speeds, thereby people often drive them hard to avoid the rolling). This is a generic statement for all fin stabilizer systems, with Vector Fins™, this improves even further, as described later for the added benefits of Vector Fins™.

What do stabilizers do?






Fin stabilizers is the only system that handle well both cruising and “at anchor” use, with the “at anchor” stabilization force deciding the size of the fins.

Fin stabilizers is the only system that handle well both cruising and “at anchor” use, with the “at anchor” stabilization force deciding the size of the fins.
This is 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 which in turn can result in the stabilizers having more
negative side-effects like causing yaw (steering effects) and sway (side-way movements).
Thereby, the overall situation often results in a compromise in fin size, so that most fast boats today do NOT
have as much stabilization as most boat owners really want.
That is, until now!
Introducing a revolutionary generation of fin stabilizers


The Vector Fins™ stabilizers dramatically improve the roll reduction efficiency while at the same time reducing undesired yaw and sway motions caused by active fins.
Vector Fins™ - a simple solution to a complex problem!


Vector Fins™ - a simple solution to a complex problem!
The Vector Fins™ stabilizers dramatically improve the roll reduction efficiency while at the same time reducing undesired yaw and sway motions caused by active fins.

The huge benefits both in efficiency and reduced side-effects is beneficial for all boat types. This is particularly important for today's modern, fast cruisers where traditional flat fin stabilizers have typically not been able to satisfy the desired roll reduction without causing too many side effects.
The low weight and speed-efficient hull design cause short natural roll periods as well as it being easier to feel negative motions like sway and yaw in a lighter vessel.
Also, these hull designs follow the waves more rigidly and thereby require more stabilization force to be applied faster due to the shorter roll periods. So to avoid negative sensations for the guests, it is important to apply forces in the right direction.
This finally enables the use of fin stabilizers, getting all the benefits of a stabilization system that works well at "AnySpeed" also on smaller, lighter and faster vessels than what have traditionally chosen fin stabilizers.

Underway
Unlike Gyro stabilizers that always have the same maximum total force they can apply to reduce roll, independant of boat speed or roll periods, fin stabilizers increase their stabilization force by both speed and roll period when "cruising".
Fin stabilizers increase the possible force they can apply by the physical law of all forces where speed is a factor, by speed2, meaning a dramatic increase. Typically fin stabilizers do not totally utilize this potential because the forces become huge at higher speeds, so they are naturally limited by the force the actuator can apply to turn the fin to higher angles.

Typically fin stabilizers do not totally utilize this potential because the forces become huge at higher speeds, so they are naturally limited by the force the actuator can apply to turn the fin to higher angles.
Fin stabilizers will also be able to apply a more total force to counter roll in a long roll period than in a short period. This is because it is the total force impulse over time that is important, and with the counter roll force being caused by the fin acting in an angle on the passing water, it can continue for an unlimited period.
The force impulse is named "Nms" - Newton × meter × second, so with the time factor being principally unlimited, so is the force impulse. This is a huge benefit because bigger waves are typically longer, so this is not just theory. While underway, Vector Fins™ typically improve the roll reduction efficiency by about 30% compared to standard flat fins of the same size.
Due to the Vector Fins™ unmatched effiency, the Side-Power system is therefore capable of reducing uncomfortable rolling motion of the boat up to 95% while cruising even in quite large waves, keeping you and your guests both comfortable and safe on board.

As most boat owners spend more time at anchor than underway, it is critical that the stabilization system performs well at any speed, including no speed.
A stabilized boat offers a significant increase in onboard well-being. Moving around, getting the tender out, serving dinner or just getting in and out of the water for swimming becomes a lot easier and safer from a stabilized boat.
A good Any Speed stabilization system allows for comfortable use of your boat when you otherwise would, or at least should, have stayed in port.
At Anchor
Up to 50% more efficient than flat fin stabilizer systems. Spend those amazing nights at anchor under the stars in a bay - instead of a busy harbour!

Why are the Vector Fins™ so much better?
The Vector Fins™ simply re-direct the force direction/force vectors so that more of the force will benefit roll reduction and less force is wasted on the negative side-effects of yaw and sway that is unfavorable for a boat's handling and comfort on board.


The vertical concave shape of the fin creates a net force direction, both in cruising and in "At Anchor" situations, so the work is more "up/down" instead of side to side or almost horizontal, as flat fins work with forces parallel to the hull angle.
But there is more. By changing the net force angle, this also increases the leverage arm around the boat’s rolling point, further increasing the physical forces that work on the boat to reduce roll. This provides a lot more roll stabilization per fin size, which means that drag, power consumption, internal space occupation as well as load on the mechanical parts is a lot less than with other fins that can give a similar roll reduction.

The compact power packs can run the stabilizer from the generator power at all times. An optional load sense pump can also be added to allow for stabilization while underway and with the generator shut down.

This pre-made system is used for installations where the vessel does not have a hydraulic thruster system. All of the hose and wire connections are pre-installed allowing for faster system install and startup in the field. Side-Power focused all of the connections on two sides of the tank allowing for the system to go in tight spaces. By separating electronic control boxes the systems can be installed in engine rooms and other technical spaces.
We also offer similar pre-connected and easy to install central hydraulic systems when other hydraulic consumers, typically thrusters, are required. These have a similar level of integration while of course being a bit larger due to the higher capacities required by thruster systems. When combined with a hydraulic thruster system, the stabilizers and thrusters talk to each other via our S-link™ CAN bus system, enabling automatic hydraulic power distribution to where it is needed at the time, and even stabilizer control from the inexpensive thruster control panels.
