The WAM-V

"TheWAM-V™ -Wave Adaptive Modular Vessel- is a new class of watercraft based on a patented technology that delivers a radically new seagoing experience. These ultralight flexible catamarans are modularly designed to allow for a variety of applications and to fit the requirements of specific users, missions or projects."
Can't imagine what I'd ever do with one, but someone must have had a use for it. Here's the website for Marine Advanced Research.

Sure looks like it could be fun, and I bet it could handle some killer waves. I'd love to try one out.
