What are the best applications for designin and building a boat ?

Where did I say you had?

That is pretty much the MO of most mega yacht designers.

 

Rhino, Fusion 360, and Delftship are all solid choices—depends if you want pro-level naval design or a more general 3D CAD approach.

 

I agree that images are what sells a yacht. Few owners would care to go through all the hydrodynamic or stability calculations. They are content with the way it looks, and the specifications for speed, range, etc.

 

It’s fascinating how designing a RIB or other small boat means balancing performance, structure, and materials - and likewise, using tools that support your goals is key whether you’re building hulls or optimizing your health. Just like selecting CAD apps or doing hydrodynamic simulations are critical in the BoatDesign community, something like https://wellness‑app.com/ can serve as your digital shipyard for self‑improvement: acting as an intermitten fasting app that helps you chart out eating windows, monitor how your body responds, and adjust accordingly. You may debate CAD vs. FreeCAD vs. SolidWorks for hull shape, draft, or beam - but you want clarity, ease of use, and reliable feedback; similarly a good fasting app should offer intuitive tracking, reminders, and insights so your body performs well. Whether refining your boat or refining your daily rhythm, the right tools matter.
