Where do the costs of a bigger boat come from?

Seeing my boat is surrounded by enough snow to be clinically depressing,
I've come up with this question for you all ( while most of us await the big thaw). It's been stated here and elsewhere once you go above 34-35 feet the costs add up fairly exponentially. So let's compare my c&c 30, and a alberg 37.
Let's dismiss slip/mooring , storage /hauling, as that's a no brainer that the longer the boat the higher the marina fees. Let's keep things pretty apples to apples , both simple galleys with icebox , alcohol stoves, manual heads , Hand pump sinks, simple lighting loads etc... Just how much more does that extra length equate in added costs? Anyone have any personal experiences? I'll throw the first one out ...more bottom paint , probably another gallon , how about it,
Sail costs? Rigging? Let's throw some numbers around( what else do most of us have to do, if you live up here in the north anyway!)?

If a boat were a blob shape then costs sensitive to surface area (sails, bottom pain, deck wash, varnish, etc) would rise as the square of the basic linear dimension. Costs sensitive to volume (lead in the keel, resin in the hull, displacement etc) would go up as the cube of length. Since the basic boat shape is long and narrow this does not quite happen and the increases are less than squared or cubed, but they are certainly not linear.
