Seakeeper Ride

im not sure what exactly you are asking. if you are familiar with SKR, you know what it would do on the boat....
 
I had them put on the transom flush to the bottom into the edge of the sides of the boat. I had to have the old trim tabs removed and then glass in so that the back of the transom is completely flush as the sea keepers have to be mounted on a flat surface cost about $3000 for the fiberglass work to be done. It's well worth it.
