    Very interesting new product.

    It would be interesting to compare cost of this unit vs. larger units vs. stabilization torque generated.

    The thing is, there is nothing stopping installing multiple smaller units to a larger boat vs. single bigger unit. They could even be energized sequentially according to the sea state. The stabilization might even maybe benefit a little from having multiple units not in sync with each other… Interesting.

      As part of my discussion with Seakeeper for this product announcement I learned that their model numbers correspond to the number of newton meters per second of force the stabilizer can deliver. So, the 1 is able to deliver 1,000 newton meters per second while the 2 is 2,000, the 9 is 9,000 and so on.

      The list price on the 2 is around 20,000 which makes it $10,000 / 1,000 nms compared to $15,000 / 1,000 for the 1. The 18 has a list price of $120,000 so it’s $6,666 / 1,000 nms. I doubt that the installation of the smaller units is enough cheaper to overcome the cheaper per nms cost of the larger units. But, where multiple stabilizers can be very helpful is if there’s not a spot for one large unit.

    When a boat need multiple small units, you must start all of them, otherwise the units working can get overloaded and will fail prematurely. Installing two instead of one is only recommended when you have space issues

      Why exactly they have to be all running, if sea state is not that severe? I see no problem starting just some of them first.

      Of course they should be alternated so that hours are balanced between the units.
