What about the efficiency of this strange AM tower ?

It appears to be a monopole with a capacity "top hat" to raise its radiation resistance, with four "skirt wires" used to feed the monopole, and to improve its r-f bandwidth.

Obtaining a good r-f ground would be no problem for such a system installed on a sea-going vessel.

The slant wires look like guys to me...I see insulators at the top and no cap hat....just looks like a folded unipole with four wires. Probably short at 1224 kHz though....
Agreed on the ground ;)
 
It's a dutch pirate ship... that means, it was used by an illegal dutch "pirate" station... called "radio Veronica" back in the late 60's...

Yep, knew it was a pirate...wasnt sure which one.....Ahh Radio Veronica.....now that brings back memories (boarding parties, ships being sunk, fire started, et...all by the "state" who didnt want independant thinking or music; shades of Orwell!!)
 
The MV Communicator was used by Laser 558 in the mid 80's with two 20Kw CSI transmitter. Too many sparks flew when both transmitters were combined so never reached it's full power potential.

This vessel was later fitted out by Dutch engineering company Nozema with a new 25Kw solid state Harris TX for licensed station 'Q The Beat' who broadcast on 1224Khz. This company also installed this mast.

Ship was then decommissioned and purchased by a UK buyer. It went to the Orkney Islands, north of Scotland and was used for one or more low power broadcasts. However, the vessel has now been scrapped.
Another former offshore pirate ship bites the dust.

Only two original radio ships exist, Caroline and Veronic. The latter has lost it's masts.

There is however one legal radio ship anchored off of the Dutch coast which at present broadcasts during the summer months. 1Kw into a 120ft mast though with sea water underneath it's signal reaches the east coast of the UK without any problem on 1602KHz:

Well, it was a very mediocre contraption. A vague, dissapointing and weak signal.
Consequently it got five owners and later everything was scrapped which seemed
the best choice for everyone. Something there was not good.
And standing before it gave a wooly feeling in the head i remember.
