My "80 Hunter 30 was hit by lightning while in the slip on Lake Michigan about 13 years ago. It took out the
radio, depth sounder, knot meter and every bulb in all of the running
lights.. The masthead antennae was charred to a cinder. The wiring was left intact. There were a few strange phenomena; a book in the main salon leaning against a chainplate bolt had a pinhole burned through the cover. Aside from the damage to the instruments, no other damage occurred or has been found in the intervening years.
