This Urban Legend repeats itself regularly. It has been roundly rejected. On the basis of logic alone, where are all the shattered Dynaplates? Nobody has ever posted a picture of a single
one. I have searched for the pictures.
Two summers ago on July 5 we were struck in our slip. Witnesses saw the direct hit. The Windex was vaporized; all SS antennas on the mast
top were also melted. There were only bits of SS on the deck
remaining. We lost
three radios, 5 LED lights
, 60 amp main shore breaker; 1.5 KW alternator
; fused the wiring
in the bow; all Raymarine
instruments; 18 Buss fuses
; the transom paint
cracked, etc. The Dynaplate is unaffected. Further, the 4" wide X 1/16 inch thick copper bonding strip inside the boat was also not damaged. This strip is many times less cross section for carrying the current
than a Dynaplate.
