High Torque Marine SR24?

I picked up an AO NSX this year and was surprised how large the cuddy area is on this boat. I can lay down on a horizontal pad (to the center line of the boat) and have more than expected space to sleep. My three children love to go down there when the boat is going. The only issue for me is getting down there. It's not the easiest area to access if you're a middle aged, overweight boater w/ a previous back surgery, IMHO.
