Lightning Sinks Boat with Bonded Through Hulls



The headline reads:

Lightning strikes a boat in Wisconsin and the boat sinks in less than an hour......

On Wednesday, June 8th, 2011 as the sailboat fleets made their way in from the evening races, they were glad to beat the thunderstorm that was coming in from the west. Just at dusk eye witnesses saw a lightning bolt hit a 30 ft ketch swinging on a mooring in McKinley harbor, downtown Milwaukee. " It lit up like a Christmas tree" was how one observer described the event. Within an hour the boat was under water with just portions of the masts showing.

This is what the boat looked like an hour after being hit by lightning. Still want to connect ground to your through hulls?

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
