Honestly, NC 19 looks like a fantastic Kayak but nothing (other than size) lends it to the idea that it's truly a fast kayak. It's 24" wide, and has a starting passenger weight of 190lbs. I would charactorize this hull more for a casual to semi-serious kayaker who wants a good swiss army knife of Kayaks. Though I'm sure being 19' long it has a good chance of keeping a good pace, however, I can't find any technical data to confirm or deny that claim.
PS> whats with their website ? Kind of cheapish IMHO.
