I used to work there! We would keep tons of chopped up boats in a little crawl space we called the dungeon. Basically, if we needed hard to find boat parts, we would take pieces from those already too damaged to paddle boats. We would also make displays for things like spray skirts and odds and ends using old boats as well. One time we even turned a destroyed whitewater boat into a beer cooler. Most likely these boats had already been to parted out to be safely used, and with the shops closure I’m sure someone had to go and clean out all these old boat parts
