The Seakeeper Ride kicks in at 10 MPH so it does nothing when rolling but not moving forward faster than 10 MPH.
There are other advantages to the system though. In addition to lessening rolling, it can also adjust trim when networked with the motor network. That can help keep the bow up or down as appropriate in active seas or when getting on plane.
It will also lessen listing as when your passengers move from one side to the other or when abeam seas are present or winds for that mater. The aggressiveness of the adjustments can be adjusted as can the pitch control and those variables saved in the system. With the control panel real time adjustments can also be made.
So in my mind, the advantage is that when used, you don't need to make those frequent small trim tab adjustments or as is often my case, ask your somewhat 'buff' buddies to move to the other side of the deck!
I have the system in my new to me 26 foot CC but I haven't launched that boat yet
To be honest, I have no real world experience other than my sea trial. The Ride product was not on my list of 'wants' when boat shopping. It just happened to be on the boat I bought. We will see if it is a game changer, nice, or an overpriced option.
