I've been fooling around again with the Old Town Canoe database described at http://www.wcha.org/ot_records/ to see how their business changed over time. The two charts below show the percentage distributions for wooden canoes among the most popular models as well as canoes, boats, and kayaks made out of wood, fiberglass, and ABS (a.k.a. Royalex). I found it interesting to see how much the popularity of a given model changed from year to year and how quickly plastics took over. This shows how difficult demand forecasting can be.
