Not size is the limit - money is it.
A 70 ts submarine can not have more as 30-40 m3 living sphere.
The free square meter m2 in Euronaut is about 10 by 2 meter so 20 m2 meters or 5 m2 for a crew of four and for each person. Plenty of space - a german WWII
submarine has less - and the stay transatlantic and back for months...
Not easy for sure.
