I am in need of some advice from experinced canoe builders. I have built a 15' cedar strip ribless canoe. I fiberglassed the body inside and out. The top of the seats are 10" from the floor of the boat. The gunnels are made of ash. The gunnells are about 2" wide and 2.25" high. \The boat turned out beautifully. However, it is very unstable. It is fine with a single paddler (without much wind) but once you get a second person on board it gets very tippy. I am assuming that means the center of gravity is to high. I am wondering if the weight of the ash gunnells are the problem. I don't think I can lower the seats much without having to paddle with my knees in my chest. Additionally, the camber of the hull at the location of the seats is such that I would have to cut the width of the seats to keep them in the same position or move them in toward the middle where the boat is at its widest. Because the boat is finished (and wooden) I am not too exited about experimenting with changes to the boat without having a pretty good idea that the change I am about to make will result in a more stable boat. Can someone out there give me some advice on what to do?
