American Shark Catamaran

The Shark is a design from Rod MacAlpine Downie, and is a 20' version of the Hellcat C class Cats that dominated the early years of the Little America's cup. She was a rival to the Shearwater iv in the mid 60's. The Shearwater iv was the "B" class version of the Shearwater iii, with added sail area to bring her up to "B" class max.

She does look dated compared to the Tornado, but that is mainly because the Tornado was pretty much the first of the Catamarans that modern day boats are based on, so "the look" is familiar. In comparison to dinghies, very few of the 1960's Cat designs have survived, to it is great to hear the Shark is thriving across the Pond. 

Yes, but not because it looks dated.

Come on Scooby, you should know better than to troll with comments like that!
