What do you guys think of the North River Seahawks?

I've never been on one on the water, but I checked out ShaneO's 21ft when he had it. Seemed pretty well thought-out.
The 20' pictured here, has a 14/29 deadrise as opposed to the 21's 18/42, which could be a significant difference.
There's lots of NR Offshores running around our parts but I've never really paid much attention to these canvas-top jobs.
