The guys I sailed with on my college sailing team went ice-boating. Because of the unusual aerodynamics, an ice boat can move three times faster than the wind speed. Check out this video of iceboating on Maryland’s Eastern Shore.
Smith Island, about which I wrote several months ago, was completely surrounded by ice during the winter of 1977, and supplies had to be flown in by helicopter.
What’s incredible about the Chesapeake freezing so far south is that the salinity at that part is quite high… and salty water freezes more slowly than fresh water.
To everyone out there coping with frigid temperatures, please be smart and stay safe!
