This is the experimental WAM-V, Proteus, presently undergoing sea trials. WAM-V stands for Wave Adapting Modular Vessel and, supposedly, this one is ocean capable. Powered by twin 355 hp Cummins diesels, she stretches 100' x 50'.
The principle idea behind this concept is that the hull shape and form permit it to bend and flex instead of fight the motion of the sea.
To be honest, I'm not convinced of her sea keeping. I'm even less impressed by her looks. I think I'll keep an open mind and wait for the final verdict.
The Hickman Sea Sled was a great concept and an even better boat but you don't see companies rushing to build them. Come to think of it, the SWATH is a pretty good concept, and yet, it's another idea failing to break industry records.
Bottom line, it's hard to beat the traditional mono-hull for cost, sea keeping, and practicality.
