Stabilizer on R31

Does anyone know if I can put a stabilizer, such as a sea keeper, too, on an R 31 with a generator. If so, where would it fit? And how well would it perform?

It's generally not advised to retrofit a Seakeeper into an existing boat. Much better to have them installed by the manufacturer, as normally the boat will have to be 'beefed up' in the key areas along the stringers and the hull where the Seakeeper sits. They can exert tremendous forces on the boat, and have been known to rip boats apart that weren't sufficiently built for the strain. Even boats built for seakeepers have been damaged when running on a plane with them on, as the boat wants to heel into a turn but the seakeeper prevents it, twisting the boat like a pretzel.
I wouldn't install one without the advice and consent of Fluid Motions.
