Bzzzzt, Wrong answer, but nice try. Would you like to try again for
what's behind Door No. 2?

Marine SSB Radio Systems do NOT need a direct connection to Sea Water
to operate. Not even to operate efficently. What the Antenna Systems
of a Marine MF/HF Radio need IS an efficent Coupling to the water.
There is a Giant Difference between "Connection" and "Couping".
On a metal hulled vessel the difference is moot, but on wood and
plastic hulled vessels, the difference is Extremely Significant.
