Looking around the various sites on the internet, the common year when talking of the final demise of the Mebo 2 is 1984.

I don't believe this to be true, the main reason being as follows. In 1982/83 I worked for a station in Ireland where Robin Adcroft/Banks(RIP) was our chief engineer. As you would expect, we had many anorak discussions and during one of those Robin mentioned that the ship had already been disposed of. I am pretty sure this was in the early days of joining our station which would make it autumn/winter 1982.

Robin was always clear that he did not witness the end of the ship, but he did decommission and remove the studio and transmitter equipment that was put into storage near Tripoli. There were rumours during the Libyan revolution that former Mebo transmitters were used by the rebels. Robin thought this to be highly unlikely, as the transmitters were in a poor condition back in 1980 when removed from the ship due to lack of maintenance by the Libyans.

There have been so many stories of the Mebo being sighted over the years, but probably just stories.
