The bridge looks steam punk with the radar and polished wood and brass.

It looks like what it is, an actual steam powered yacht, no
Steampunk silliness required.
Plus remember Steampunk adds purposeless gears and various "brass" constructions that
flat out wouldn't work and be heavier than if made of steel or iron.
It would be interesting to see a pic of
Delphine's bridge before modernization.
