I'm thinking about buying a K-79 Tahiti myself (like I really need another boat). You can use the folding seats for canoes/yaks, or glue some D-Rings on the sides and use the deluxe seats with straps to brace the seat back.

Does yours have the skeg? They can be retro-fitted for under $25.00. From what I have heard, adding the skeg makes it track as well as any canoe.
