If the top of the range model was only $45,000 then the upwardly mobile executive would not derive enough status from his peers knowing that he was only driving a $45,000 car, so they charge $80,000 for it.

What has this got to do with catamarans? They cost more because everyone knows that they're the guys with the big bucks!
So the extra bedrooms , bathrooms, living area and extra engine/ saildrive are all no cost items to the builders?
Do Yanmar do a buy one get one free engine deal for cat builders?

Mmmmmm

Re: why do catamarans cost more than monohulls?

wouldn't it also cost more to build a strong cat simply due to shape?

a mono is more like half an egg, a naturally strong shape.

Usually taken care of by designing shape into the hull with curved shape, bulkheads or chine like sections. more importantly consider the surface area, two hulls, two decks, under bridgedeck, cockpit, and cabins.
All of that requires materials, laying up, bonding and final finishing= lots of square feet = $$$$$

But it IS difficult to attach lead keel to an egg ... ;-)

There is a series of challenges and offsets in both designs. And they get addressed in specific ways so it is hard to impossible to tell what is 'stronger' or 'easier to build'.

You know, monos tend to have 20% to 50% of completely useless displacement designed into their ballast. Then a cat does not need ballast (nor its attachment points) and so can be built lighter and sail faster. Then again, mono will 'give' so that any sudden loading on the rig will be dampened by the boat healing while a cat is a 'stiff' boat and so needs a much stronger (a mono sailor will shout here: 'overbuilt!') rig ...

So to say - each is different and has its own benefits, shortcomings and associates challenges in building and sailing them.

Hug,
