...you show and mention that the stern sits a little high in the water when you solo from the front seat, and you levelled that out with 30 pounds of gear in the rear of the boat. Would it be safe to assume that if you happened to solo this boat with no ballast, that the sailing rudder would sufficiently eliminate the problem of the rudder sitting too high in the water?
The Oasis now comes with the large (sailing) rudder as standard equipment. In the following pic, you can see that, even with the stern a little high, there is plenty of rudder below the boat and control is not an issue:

Most boats perform best most of the time when they are level in the water or "on their (design) lines" The primary purpose of the ballast is to accomplish that. Obviously rudder authority would increase as well as more if it engages the water.

I've never seen the sailing rudder for boats like these, as my wife's Revolution has the standard rudder, but I assume that it's similar to my AI's rudder. I would assume that the sailing rudder would go deeper, and that the steering response would be restored to at least what the standard rudder would supply...
The large (sailing) rudder is the same for all hardshell models (except the TI and 2011 AI). It has double the surface area as the standard rudder. Not only is it deeper, but much broader. the following pic shows the standard rudder overlaid on the large rudder:

On all the boat models, the performance difference is significant -- it's like getting racing tires for your car. Response is quicker and snappier, turn radius is reduced, directional stability is enhanced and low speed control is greatly extended. As an experiment, try your AI rudder on your wife's Revolution and see what you think (they can be swapped out in less than 10 minutes).
