i have to agree with Hoz and Mr. Krabs on the double paddle issue. double paddles are for kayaks. Rushton designed a small solo canoe that was called a 'double paddle canoe' and i built a modern version of one (called the "Wee Lassie") in cedar strip/epoxy construction. it was a terrible boat. slow and unstable. i also built a double paddle to try with a 15' Hiawatha canoe that i built. it made the boat go fast but it just felt 'wrong'. i'll stick with single blades for canoes and doubles for kayaks.

What are the advantages to using a Decked Canoe vs. a Kayak? Is it only cargo capacity or the amount of weight you can carry? This might be a good option for bigger folk like myself. Could you use a kayak paddle to propel yourself or would it be to awkward to manuever yourself? Wondering if I could build a Canayak? Any thoughts on this?
kayaks are faster.
canoes, decked or not, can carry more load.
there are a few older designs kicking around for free on the 'net of decked canoes and/or open cockpit kayaks that might suit you. if i can find them, i'll post links.
