    I think this would be better off as a dynamic diver ballasted slightly bouyant.

    What if you used a water pump for thrust and moved the end of the exhaust tube around like the kort nozzle moves. Maybe x-tail mixed controls.

    After seeing the video of the finished product, I may just wait until Nautilus Drydocks brings his new "Blue Water" boat out! I am looking for a smaller type sub for swimming pool operation!

    It doesn’t have a kort nozzle. The prop would be inside the shroud if it was a kort, it’s got vectored thrust and the prop is inside the hull. Doubtful you’ll get any reverse thrust with such an arrangement, so perhaps that’s why the designer has gone for a bow thruster to get out of a tight spot.

    Thanks Romel,

    As soon as I get a little more ahead on my Alfa build, I will start printing out this little jewel. It really looks like a good project!

    Thank you very much for all the info you have posted up on this project!! :-))

    If you look in Tiver21's YT album you'll see most of the videos showing building process and bathtub testing but very few actual deployment in the pond or pool.
    Thanks Romel!

    I will check it out!

    I really like this, though!

    As Bob has stated, with the kort nozzle being aft as per design and it's possibility ability to really turn well, why would you need bow thrusters?

    Romel, I have been looking for a YouTube or video of the whale actually in the water doing it's thing, but I have not been able to locate it! Have you located one yet? This whale is starting to tug at me for a build!
    The stern fin really printed out well and that was going to be my go a head piece for the project if it turned good!

    I am holding off a little because I know Bob has some smaller type 3D printed boats that really look good for the swimming pools as well, and more to come!! I am so hooked on this hobby!!

    Maybe swap out the paddlewheel for a centrifugal type pump like those used in windshield washers.

    That would have been awesome, but I'm 90% sure that's a bow thruster. Looks like a standard paddlewheel style, and I can't see any outlet running to the upper hull.

    Ditto on the location of the intake for the propulsion.
