It looks like the only Ride version that'll fit your boat is the 450, for $4500. Is that the price installed, or just the cost of the unit itself, and installation is extra? That seems like it would have turned your day on Lake Michigan into a multiple hour fun excursion with the way it definitively affected the movement of the boat in the video.
Not sure how much your prescription meclazine runs, but this system seems like it'd eliminate that cost for you, or at least allow you to drop to an OTC version that could be easily obtained. The cost of NOT having to dose your system seems like it'd be priceless, for as much as you're affected!
Also, when is your installation appointment scheduled?
