Design of double chine flat bottom fishing canoe for lake fishery
A 7.0 meters Length Overall (LOA) flat bottom canoe similar to the one commonly used for fishing in Kainji lake, but with some modifications, was designed. The improvements/modifications over the local canoe include, an additional chine to reduce the flatness of the bottom which was absent in the local canoes commonly used. The canoe's light displacement (weight empty) was 0.48 Tonne, which was similar to local canoe of same size. The draft obtained was 0.13 M( 13cm), which is 36.9% of its depth (0.48 M). The capacity of the canoe was 1.304 tones. The water plane area (WPA) was 3.89 M2; WPA coefficient, and block coefficient were 0.83, and 0.82 respectively. The modification on the canoe resulted in provision of a canoe with the bottom shaped close to V-bottom to aid better performance on rough turbulent water such as the Kainji Lake, and increased life span of canoe and safety of fisher folk while aboard fishing.
