Have you checked out the Adirondack Guideboat? Suitable for larger water than some canoes, rowed or paddled, higher ultimate stability, faster, The Adirondack Museum in Blue Mountain Lake New york has many fine museum examples of this type. A builder in Vermont is making them in Kevlar. Kinda pricey but these boats are enjoying a comeback around here. I have a few photos on my website at
