Last August while in the slip in Kemah Texas, Yaga took a direct hit which destroyed the following; alternator, engine oil press and temp gage, engine alarm module, both A/C main control boards, one A/C thermostat, AB freezer control board, VHF antenna and radio, wind sensor and control head, depth instrument and speed instrument. The techometer, Garmin GPS, AB frig, microwave and TV/VCR survived. Boat US insurance was great. But the experience was not. Since then we have added Raytheon AP, radar, fishfinder / chartplotter, an Interphase scanning sonar and second VHF so we worry when T-storms come our way. This Saturday while at anchor in Warton Creek on the Chesapeake the typical afternoon storms were marching across the bay with lots of lightning. So I turned off all power and disconnected the antenna connectors from the back of the VHFs. As the third storm passed by, Debbie said "Looks like that one missed us too". I felt an air of 'Ha, Ha missed' in her voice and told her, "You should be careful HOW you say that". A minute later - Crackel, crackel, flash, BOOOOM! Another DIRECT hit to Yaga. One of the skippers in the many boats around us (we had the tallest mast) yelled over he saw three bolts light up our mast and wondered if we were OK. We were sitting in the cockpit under bimini and dodger and the electrical sound of snapping and crackeling was very loud just before a blinding flash of light followed by what felt like an explosion. It was weird but I felt very calm and told Debbie to also remain calm, (she looked a little shakened). I went below to check the bilge for any signs of leaking from blown out thru hulls. We waited 10 minutes for the skies to clear and then began to turn power back on. ALL systems were A-OK and the A/C units worked fine back at the slip. We do have a Forespar dissipator on the masthead and the mast is bonded to the keel. Only difference I see is the first hit that caused the damage was in the slip with shorepower connected. Go figure.
