The Ocean from 1805 and the Impregnable from 1810 are clear representatives with a hull of 6 and 11 boxes, each with over 2250 bm. They are even heavier than the New Boyne class.
And finally, of course, the ships of the Trafalgar and Princess Charlotte class.

The extended Prinz comes with 2088 bm of course very close to the limit and if it had been built directly, I would also tend for hull 6 there. But this way she gets the maximum body 5 version - with 11 boxes and 55 points. Maybe I'd give her a maneuver class better than the other 90/98 ships. Or the card deck "I". Whereby the Boyne 1810 and Union 1811 should be reserved. As DB has already written. Makes perfect sense.
