One of my high school teachers retired and bought a river paddle boat to put a restaurant on it. The idea was to cruise the local bay and provide a nice dining experience. Two years into owning it, the hull started leaking quite substantially. Apparently, the hull had not been maintained properly over the years and was now dangerously thin. The boat ended up being scrap. I guess they weren’t bringing in enough profit with it sailing, they didn’t even try to land lock it.
