The only 2400 Mhz RFI source on your boat is probably your microwave
oven at 2450 Mhz. There is no interference from 150W of HF through
the wireless.....LIKE THERE IS ON EVERY WIRE OF THE NMEA SYSTEM aboard
the boat. NMEA wiring cannot be effectively shielded as long as.....

You just take every opportunity for a rant about NMEA, don't you?

Why would NMEA at 4800 baud produce more interference than a 100mbit network
on UTP (U=Unshielded)?

NONE of the plastic boxes the damned cheap marine crap comes in is
shielded in the first
place against the HF transmitter or your 5W walkie talkie on deck.

Another one: It is NOT necessary to put electronics in a shielded boax to be
EMC proof. It all depends on proper PCB layout. A lot of equipment in
plastic unshielded boxes carry FCC or CE approval. They don't get that
approval when the equipment is radiating like hell or going dead when keying
an SSB.
