Magooch, your obvious enthusiasm for NC kayaks has led you well beyond simple advocacy into Derek Hutchinson-like certainty: "...the NC Expedition is without doubt, the boat to have if you are serious about sea kayaking". My latest favorite Hutchinsonian utterance comes from some notes in a Canadian paddling journal, 2008: "If you want to paddle successfully, you want a 90-degree feather. I use a 90-degree feather".
Seriously, I think I'm a reasonably serious sea kayaker, but even I don't have an NC Expedition. I'll bet Derek Hutchinson doesn't have one either.
