A courting canoe by definition is a canoe for a couple to court in as Kathy mentioned. This means that any canoe which can hold two people could qualify. (I suppose that a narcissist could court themself in a solo canoe but that would be a special case.)
The courting canoes in the early 1900s often included things like long decks, extended torpedo stems, high tips, lots of mahogany, fancy paint designs, closed gunwales, and other features. The analog today is to have a sports car or to 'pimp your ride' for cruising. There is no hard and fast rule that a courting canoe is required to have all or a specified number of these features so you will probably get as many answers as people you ask. An Otca typically has twenty inch decks with high tips and a nice round stem. I will go out on a limb and suggest that an Otca with unusually long thirty inch decks, in AA grade with all mahogany trim, closed gunwales, and a fancy paint job could be considered a courting canoe, especially if you add a fan back rest, pillows, a nice picnic lunch with suitable beverages, an attractive partner, on a relaxing summer afternoon, etc.
