Frequently Asked Questions
Since the speed of planing vessels is higher than that of displacement vessels, the fin stabilizer system is generally used during the anchoring process. For this reason, during the design stage of the system, care is taken to ensure that the fins give maximum effect to the vessel while standing still, and not to increase the resistance effect in a negative way.
Systems operating during the anchoring process need more torque and power and must be able to demonstrate quick reflexes. In this case, systems require larger units in terms of power and volume.
Fins are controlled via a touch LCS panel placed on the deckhouse. The captain is able to make the necessary adjustments according to the demands of those on board in manual mode, as the system detects the numerical values of the factors such as wave and speed in adaptive mode and adjusts the fin movements electronically.
The electronic control system, one of the most important features of Stabilis Electra, ensures that the fins are brought to the safe zone, which is the “0” position.
It is not recommended to operate the fin stabilizer system while the vessel is moored to the quay or marina with ropes, and undesirable situations may occur as the fins may go beyond the maximum width of the vessel during their movement. In addition, since there is a force on the ropes at that instant, the system should not be expected to give the desired reactions.
There is a skeleton structure made of stainless steel inside the fins. On this structure, there is an outer wall made of fiberglass. Meaning that the fins are designed in such a way that they prevent damage to the hull wall as well as absorb the impact in case any object hits.
Theoretically, we can say “yes” to this question but in practice, the resistance of the fins is compensated by the improved stability.
If you fill out the information form to be submitted to you by BTS Marin, we can select the most suitable system for your vessel. Speed, weight, and stability values play a significant role in the selection of the system.
In underway the system requires less torque and power and the fin areas get smaller, which leads to the use of smaller engines. For this reason, the systems that are intended to be used in underway only will be reduced in terms of power and fin area as well as decreasing in price without losing any value in terms of their features.

The system is warranted for 30 months from delivery, as long as proper storage conditions are provided, and for 24 months following the commissioning by CMC Marine/BTS Marin.
Compared to the existing fin stabilizers on the market, there is scarcely any maintenance and repair cost for Stabilis Electra.
Please contact the BTS Marine representative in this regard.
When the selection of the fins is over, the concentrated load values on the vessel will be given by CMC Marine and the relevant strengthening composition should be prepared by making calculations accordingly.
In order for the fins to perform at a high level, attention should be paid to the angle of the fin axes with the vertical plane and care should be taken to ensure that their longitudinal positions are close to the vessel’s rotation center to avoid a rudder effect. Thanks to the small size and silence of Stabilis Electra components, it can be placed in sections close to the living space of people without any problems.
Yes. Our actuators can rotate the fins 360 degrees. However, this feature is optional. The fact that there is as little distance as possible between the upper edges of the fins (stabilizer blades) and the hull and that water escapes as little and difficultly as possible from this distance during movements is a factor that primarily affects the performance of the system. Even though certain manufacturers claim that this is a prominent advantage, the upper rear corners
of the fins are cut into triangles, especially in vessels with chine, so that the fins can rotate 180 degrees, and the system performance is dramatically reduced just for the sake of this feature. As BTS Marin, we examine the form structure of your vessel and share our ideas in this regard with you at the purchasing stage.
Yes. This feature is also offered as an option in fin stabilizers of certain sizes. Since our systems operating with AC power do not need batteries, they do not impose an additional load on the service batteries that feed the other systems of our yacht, and thus, do not shorten their life.
