Bonding and Grounding Checks [Re: Triatic , and use for SSB.]
I am pretty sure the 802 was not yet on the market when your boat was built, so its wiring is aftermarket. Amel's original purpose for rigging the triatic as an antenna was for feeding a signal to the weatherfax receiver that was an optional feature on the Super Maramu. With standalone weatherfaxes now pretty much obsolete, its use as a DSC signal receiver for the 802 is a good one.
But does anybody actually uses SSB DSC?
The triatic's location and configuration would make a poor choice for a primary high power send and receive antenna for an SSB.
As a VHF antennea, I'd be skeptical. Its length would probably make it a very high gain antenna, unfortunately not focused in a useful plane. It would broadcast and receive in a plane perpendicular to the length of the wire... pretty much straight up and down. Maybe good for communicating with satellites, but not other boats.

The Triatic is about the correct length (a little too long) and height for VHF radio, which includes AIS. I am not aware of anyone trying this, but many Amels had a coax cable from the Triatic stay to the back of the nav station. That coax is probably OK for receiving, but maybe marginal for transmission.

Re: Triatic radio aerial.
I recall (but cannot find the reference at the moment, unfortunately), that the Triatic is the aerial for the reception (and transmission?) of DSC signals used by the SSB HF/MF radio. At least, that is how SM#396 is rigged (IC-M802).
For info, the recently decommissioned Furuno FAX-30 RFax/Navtex receiver (and not to be confused with a FA-30 RX-only AIS black-box) used a stand-alone whip-aerial located on the port-quarter.

First of all, thanks a great bunch for a fantastic feedback, which is greatly appreciated.
As a part of my standing rigging upgrade, this winter I have ordered from ACMO a new triatic with required isolators to potentially use it as SSB antenna, when and if I decide to invest in this system.
So incidentally I was wondering whether you could also advise me and other interested parties on the best SSB radio set currently available for sale.
Thank you very much,
