Lovely drawing, heuhen. Although it feels a bit stretched to me. I think it could benefit from being about 200 ft shorter at the stern.
If I did that I would loos 1/3 of the car capacity of the ferry.
the length of the vessels is inside the limits. it is also not as beamy as Ace's ferrys. but at the same time I have similar car capacity as him. The reason for my ferry to not be so beamy is because I wanted that little extra sea-capability when traveling with or up against weather. but I do also get a tiny better full consumption, (but that depends on the engine setup). main design have the advantage to be an three stage design layout. that mean more customers can be interested in this design and thus cut down the cost of the ferry.
stage 1 design layout: two large car decks, cabin areas and a cargo deck aft. Some ferry companies want that.
Stage 2 design layout: two large car decks, large superstructure with a lot of cabin, lounge and restaurant space.
Stage 3 design layout: two large car decks, and a supper-sized superstructure.
But the paint work do also affect the stretch look to!
