    Any feedback on gyro gale stabilizers? They use either 2 or 4 small fins and are pneumatic instead of hydraulic. Manufacturer claims numerous benefits with pneumatic plus some reduction in pitching with the 4 fin system

    I ran a couple of boats with them. While they worked well I did have an issue were one fins mounting tube bent for no apparent reason. I have not run a boat with their new fin design.

    Pascal, Did you have any specific questions about them?

    Thks bill. Not really I was just trying to learn about them out of curiously at this point... They dont seem as popular as Niads... pneumatic seems simpler than hydraulic

    They are simpler as far as running air lines and the fact if they leak you don't have oil going every where.

    But I'm not sure the old style fins where as effective at low speeds as the traditional hydraulic fins are. Now with the new style fins they have with there articulated trailing edge that may have changed.

    Are you considering putting fins on Charmer?

    If it was up to me, I would :). With the enclosed FB, jet ski and 15' tender up there she s a roller!

    I always thought it was odd that it came without them. Was it an option in those models?

    It is interesting that they Gyro Gale offers zero-speed stabilization. We had that on the 140' I was engineering on for a bit and once you have it you never want to be without it.

    The units I worked with were the originals which did not have that. Nor did I have the new digital controls that correct for pitch not just roll and list.

    I wonder... There is absolutely no room the ER to add them, the only place would be just forward of the ER in the port and stbd SR but limited room under the beds. When you figure 100k cost, it pays for many wait n see days !

    I have been presented a used package of Gyro-Gale stabilizing equipment.

    I have fantasized on installing stabilizers on our '78, 58' Bert MY for a long a long time.

    I have witnessed it (Gyro-Gale) work on one boat years ago and was not impressed. However it was an ugly day in q/following 4' seas.
    I was delivering a Flemming a couple of months ago in similar seas and the Naiads seemed slow also. So maybe the Gales weren't to bad on my only experience with them (stern Q's sux).

    I like the idea of air over oil, but can not believe that an air system can react as fast than an oil system. It's that simple theory thing ringing in the back of my head.

    So, anybody have any more input on the Gyro-Gail stabilizing system?

    They're not very good, they help a bit but not like oil driven ones. The reason nobody uses air is because it compresses. So in rough seas the force on the fins compresses the air as it tries to push the fin out. They either used an engine driven compressor like lazzara or a very large and noisy 220v compressor that uses about 20 amps and seems to run constantly. So they take a bit of power to run. The fins are not strong enough and if you have a 4 fin setup, you're going to lose one from it's shaft about every 3-4 years. They use 4 fins because they need 4 to attempt to do what 2-6 sq ft naiad's do. There is no way to set them straight either, they're either on, or flopping around if they're off. If the boat has them and they work, they're adequate. I'd never recommend purchasing a set.
