Exploring Womp was informative. I won't revisit it soon though. The free version is very laggy, because of the constantly streaming nature of the online tool.
Also, the more interesting features, such as textures, are paid-only. The free features are very basic.
#MagicaCSG is the go-to tool if you'd like to enter the world of SDF modeling.
@pafurijaz I gave the hull a little try. 🙂 For reference I used the drawn boat blueprint and your subdiv-modeled 3D boat, so it has become a bit of a blend between those references.
It's just a 20-minute eyeballed simple experiment, and the hull isn't open, because that would require more work, and will be much easier once the nested SDF primitives are added (the #MagicaCSG dev is currently working on that).
