BMJR Models Splash-E
I finished this plane a little over a week ago. It's a cute little small field flying boat. It hasn't flown yet, but I did some taxi tests. The wind was too strong to attempt a maiden flight - particularly because it doesn't belong to me.
The only problem noted was expected. It has no water rudder so I couldn't turn it around. I just waited for it to blow back to shore while using rudder to keep it steared away from weeds. This was at our field that is currently under water due to the hurricanes this season.
Anyway, a rudder could easily be added. Details of the build on my site:

RE: BMJR Models Splash-E
You can steer with the air rudder, elevator, and throttle.
To go upwind, just let go with lo idle or stopped motor and the plane will weathervane into the wind.
To go downwind, hold full UP, add about 1/3 throttle. and the plane will lift up onto the tail end of the float, and will weathervane downwind.
Reducing the throttle some lets the front part of the float find its way back to the water....by careful manipulation of the throttle(Still holding up elev) you can balance the tendency to turn upwind or downwind, and steer with the throttle and with almost no correction from the rudder.
People put water rudders on their floatplanes planes and expect to drive them around like RC Cars....it doesn't happen.
If you have propblast over your air rudder, you can steer without a water rudder. If there is no propblast...it doesn't matter.

Hi Jim,
That's pretty much what I did. When I tried to steer with rudder alone, the model tried to dip its wing tips in the water. Eventually I was holding full down elevator and using aileron to keep the model level while using rudder to steer. But the model pointed into the wind the whole time. The best I could do was to get the model to move back and forth.
Thanks for the information. I don't know a lot about seaplanes as you can see. I figured a water rudder would at least allow me to turn the plane around.
