Bob,
SEAHORSE is 65' LOA, aluminum hulled. The mast is 3" aluminum pipe
tripod which was roughly parallel to the affected antennas. I could find no
burn or scorch marks anywhere on the superstructure exterior, so from what I
can tell the antennas took the brunt of the strike.
The coax from all the antennas are protected by polyphasor bulkhead mount
arrestors already. The problem apparently was the antennas themselves
could not carry the current & were destroyed.
The on-board electronics are protected with MOV's wired to ground,
shielded twisted pair on all the signal,data, & power leads.
