As an aside apropos of this. I paddle with my buddy in his feathercraft K2. It has a rudder. It is designed to paddle with a rudder. We found out on a 4 day trip that we left it behind in my van at the takeout. So off we went and we could barely get the boat out of the creek. With a light cross breeze we were working like dogs to stay on course. So, not to say die and loving to solve problems we came up with a fixed skeg from the spare paddle. (tie wraps, baby...don't leave home without them!) Next day I got it up to an adjustable system with cords and adjustments for the sternsman to set the angle.
Bottom line.... this is a Rolls Royce of boats, but its gotta have the rudder.
(actually this is just a chance to see if I can include a photo in a post and to show how clever I am... I don't get enough validation, I guess).
