The bottom sections are fully conically developed, which ensures that the fore body and after body are very strong, exceptionally rigid and very light. Note the amount of curvature in the first two bulkheads above. There is no torturing of the ply whatsoever, and the panels bend naturally to shape. Once the bottom is joined together, each side can be sewn on in 20 minutes - apart from the last 18 to 24" of the stern - see left and immediately below - where, because of the very full stern in plan view, very flat buttocks in profile and flared topsides, it might well take an hour to ensure that each panel is absolutely perfectly aligned. This type of stern has considerable reserve buoyancy, unlike the slim conventional canoe sterns, as well as being attractive, so perhaps the extra work can be excused, but is less suitable for the inexperienced builder. Note, too, how well the panels fit together. In the photo on the left can be seen the small plywood tabs that maintain perfect alignment at the keel, and which are removed later
