On Wednesday, June 8, 2011, frequent cloud to ground lightning was seen above Milwaukee. That's when witnesses saw a lightning bolt hit a 30-foot ketch on its mooring in McKinley Marina near downtown. "It lit up like a Christmas tree," was how one observer described the strike.
Within an hour the boat completely sank. The cause was an old bronze through-hull that was completely blown out of the hull by the strike, leaving a 3-inch hole. Two Forespar products could have helped prevent this disaster.
Our Lightning Master ion dissipater could have reduced the build-up of static ground charge, retarding the formation of the ion "streamer" that completed the path for the lightning strike.
Nonconductive Marlon composite through-hulls would not have attracted the energy from the bolt like the bronze through-hull.
