Yacht Lightning Strike.

I wonder if the mast was bonded to hull fittings that were below water? The hull is probably made of glass fibre (G.R.P.) which is electrically insulating, but perhaps not if subjected to thousands of lightning Volts. Or was there an electrical path via internal bonding within the yacht?

    From memory, the relevant international standard published by IEC (IEC 60092-507 which calls up IEC 60092-401) requires the mast to be bonded to a copper plate below the waterline with a surface area of 2 square metres. I have never seen such a system on a yacht and most yachts seem to use a published ISO standard which seems to ignore such safety issues (or they don't use any standard).

    I doubt if the mast was deliberately bonded to the electrical equipment but there would be enough mutual inductance between the mast and any adjacent cabling to fry the electronics.
