Hi there,
This is Bogdan from Romania. I'm a mechanical engineer, 3D designer and modeler. I have over 15 years experience in designing, engineering and prototyping of various systems/devices/models.
As per your project, several images and some basic measurements (for reference) should be enough.
Based on your pictures, I'll use my 3d scanner (Fusion 360) to get a rough 3d model of the boat.
With this rough model, I'll make the parametric model in Autodesk Inventor.
With your assistance, I'll modify/adjust the shapes/dimensions until the desired outcome is reached.
Once the final model is approved, I'll send you the files in different formats(iges, stl, stp, etc)
