RC hydroplane

[Letniq]

Hi, guys
This is a project I'm working on it.
It's a model of RC hydroplane. I intend to produce a real rc model. For now it's just on my computer.
The design of the hull is mine. After finishing it I will 3d print it in real size so I can make a negative template and produce several pieces for me and my father beacause We are both RC fans and We often go competitions The hull is already finished just some small adjusments left. I'm working on some small details outside The model will go around 70-80 km/h. Powered by Lehner 1535 Brushless motor. The lenght of the boat is around 600mm. If you have any suggestions It will be great to hear them. I'm not quite sure about the front sides hulls. May be they will be a bit longer.
If someone can suggest me a some program to import the hull and test the aerodynamic and hydrodynamic it will be great.
All comments are welcomed

An interesting configuration. What are the main dimensions of the model?

Middle hull
length: 450mm;
width 60mm;
height 56mm;

Side hulls
length: 176mm goint to 210mm;
width: 30mm gointo to 40mm; the tests will show is 40 better than 30 and then I will decide.

Overall
length: 495mm --> 529mm;
width: 283mm;
