A mid-build change order on a luxury yacht costs up to €200,000. CFD costs a fraction.

A mid-build change order on a luxury yacht costs on average between fifty thousand and two hundred thousand euros.

A full CFD simulation costs a fraction of that.

But the real cost of not knowing isn't financial. It's handing over a space that disappoints a client who had placed their trust in you.

For someone buying a forty-million-euro yacht

PMV and PPD are technical indices. But for someone buying a forty-million-euro yacht, they mean one thing only: the master cabin is comfortable, or it isn't.

At that level, there's no such thing as "almost comfortable". There's comfortable. And everything else.

Fluid dynamics simulation translates physics into certainty before the owner ever steps aboard.

The moment you know something is off

There's a moment, in every complex project, when you know something is off. You can't measure it yet. You can't prove it yet. But you sense the air isn't moving the way it should.

That moment has a precise cost: change orders mid-construction, complaints after handover, a reputation that erodes in silence. We step into that moment with science — before it becomes a problem.

Revellum's value isn't in the price of the simulation. It's in the cost you avoided.
