Direction study and start of 3D printing

- Session summary:
Working on the boat's steering and improving the modeling.

- What we did:
Brainstormed on propeller shape and steering system. Needed a fast servomotor to transform rotary motion into linear displacement.
Modified the 3D model of the boat (moved some parts, strengthened the rudder).
Start of 3D printing of the hull.

- Results / Progress :
Significant progress on the directional plan and start of physical tests via printing.

- What we need to do:
Test the printed rudder and validate the design.

- What we'll do next:
Continue component assembly and validate the interior layout.
