How do I know what stabilizer system is best for my boat? Stabilizers for vessels used to only be passive systems, like bilge keels and paravanes, but has now transformed to algorithms and predictive movement software that consists of sensors, coding, and touchscreens. It’s hard to wrap your head around the development of stabilizers over the last 30 years to where we are now. Now, we have active fin stabilizers that counteract movement to the motion of a vessel to eliminate roll. When these were introduced, they were powered strictly by Hydraulic Power Units (HPU’s). Today we have electric active fin stabilizers that are powered by both AC and DC electric. 𝐇𝐲𝐝𝐫𝐚𝐮𝐥𝐢𝐜 𝐒𝐭𝐚𝐛𝐢𝐥𝐢𝐳𝐞𝐫𝐬 𝐇𝐨𝐰 𝐢𝐭 𝐰𝐨𝐫𝐤𝐬- Hydraulic actuators power the stabilizers through pressurized fluid and are connected to the HPU through hydraulic hoses, manifolds, and pumps. 𝐖𝐡𝐨 𝐢𝐭 𝐢𝐬 𝐛𝐞𝐬𝐭 𝐟𝐨𝐫- They are best for vessels that demand power in rough conditions and more frequent operation. Boats with large engine rooms. Vessels that have other hydraulic powered equipment that they can run on one integrated system. 𝐀𝐂 𝐄𝐥𝐞𝐜𝐭𝐫𝐢𝐜 𝐒𝐭𝐚𝐛𝐢𝐥𝐢𝐳𝐞𝐫𝐬 𝐇𝐨𝐰 𝐢𝐭 𝐰𝐨𝐫𝐤𝐬- AC electric actuators have motors that are powered by the vessel’s generator, the generator or PTO needs to be running to run the stabilizers. They have quicker reaction time because of the electric current. 𝐖𝐡𝐨 𝐢𝐭 𝐢𝐬 𝐛𝐞𝐬𝐭 𝐟𝐨𝐫- Best for vessels that run their generator more often than not. If there is not a lot of space in the engine room for hydraulic infrastructure because there are less parts to install and maintain. If power demand of vessel’s equipment is high. 𝐃𝐂 𝐄𝐥𝐞𝐜𝐭𝐫𝐢𝐜 𝐒𝐭𝐚𝐛𝐢𝐥𝐢𝐳𝐞𝐫𝐬 𝐇𝐨𝐰 𝐢𝐭 𝐰𝐨𝐫𝐤𝐬- DC actuators also have motors on them but are powered by the vessel’s battery banks instead of the generator. You need to have enough charge in the batteries to run them, they can’t run forever. They also have a quicker reaction time than hydraulic stabilizers. Since there are no generators, PTOs, or hydraulic units involved, the operation is extremely quiet. 𝐖𝐡𝐨 𝐢𝐭 𝐢𝐬 𝐛𝐞𝐬𝐭 𝐟𝐨𝐫- They are quiet in operation because you don’t need generators or hydraulics powering them. They are typically the most compact and take up the least amount of space out of the three. If you have the capacity to run them overnight while you sleep, they are quiet enough. For boats that have larger capacity battery banks. Less parts to install and maintain. We give you the choice of picking the stabilizer the is the perfect fit for your vessel no matter what power option you go with. See all our options on our website: https://www.abttrac.com/
