I like big boats and I cannot lie...well, anyway, they are pretty neat. Here is a picture of some decent-sized boats overwintering at Bay Ship in Sturgeon Bay, WI. I recently read that these sorts of boats have lifespans of about 60 years, in contrast to saltwater boats that have a lifetime of about 20 years. What a nice illustration of the corrosive effects of saltwater. Another science-related concept is that of boat bouyancy and water temperature and salinity, as illustrated by Plimsoll lines.
