Sure. My mother and her partner had a 70' motor catamaran built in Chile. Custom job - designed by marine architect and customer. Custom hull, and mostly off the shelf running gear, big Cummins in each hull etc. Passagemaker, goes anywhere other than ice pack, huge range - they did a Pacific crossing a few years back without a refuel. It took a team of 20 on/off (they work on a dozen or so boats concurrently), lots of calls and meetings, and cost about $2.5m all said and done. One would assume the shipbuilder made a decent profit. IIRC it didn't require much tweaking after sea trials. The materials tend to be the cheap bit, it's skilled labour and design that costs you.
