Rc Boat hull

This is a boat hull i designed for 3d printing, Ive yet to print it, so i have yet to tweek all the mistakes. If you have any with this let me know, and we could brainstorm how to fix it.
i will design a top for it, and hopefully a wing for the back.
Overall dimensions are:
398mm150mm90mm

Like i said, this is a work in progress. Ive put this on Thingiverse because i havent been able to find one that i could print yet.
feel free to alter it and share your designs.
