Sant'antonio terzo as the ventilators are the same

Not so fast! The plot thickens.

I said that I thought the logo was familiar - I now remember seeing it on the yacht (ex-tug) DON GIOVANNI in Barcelona some years ago. As a tug she was owned by SARGENAVI of Naples. Sargenavi's FORTROSE also had the same logo design.

and perhaps it is no coincidence that SARGENAVI owned STRANTON's sister SEATON as SANT'ANTONIO TERZO

Apart from SEATON and STRANTON there is one other "stray" from the original five sisters: HART, later the Irish PORT LAIRGE II. She was sold to Dragatudo in Portugal in 2006, just about the time that Dragatudo went bust, and I have not been able to confirm whether she was actually delivered.

Meanwhile one of them became PANAGIA SOUMELA and was seen at Perama in 8/2012

She is definitely not the same tug as GENESIS 4 as there are too many differences and the chronology doesn't fit.

We need photos of SANT'ANTONIO TERZO (and PORT LAIRGE II) for comparison. GENESIS 4 has distinctive ventilators installed at some time.

Imo 5342192 tug stranton last known flag Lebanon
It seem that it's stranton
Thanks David , mystery over

Not THROSTON as she went to Pakistan when almost new as TAQATWAR and listed as scrapped there in 1989.

But STRANTON was indeed last reported sold to Lebanese owners in 1998 and under Lebanese flag until 2008, without change of name. The wheelhouse is exactly right for the Hartlepool group.

Hello for all dear friends, i search a lot to get the real imo number but i didn't get any certain one

Could it be the throston ? .

Ex hartlepool tug maybe
Hart sister to Stanton
Just a guess

KALED/TAREK not a good visual match even assuming some rebuilding - and the wrong Tripoli.
The logo seems familiar, though I cannot place it.

Possibly one of at least two tugs built in 1967 by Richard Dunston in the U.K. for the Libyan Government. "Kaled" (6713506) and "Tarek" (6720614)

Here it is looking a little better : http://www.shipspotting.com/gallery/photo.php?lid=1972813

Looks like an ex-British tug.

Ex Manchester Ship Canal tug?

Look more like wreck rather than casualty.
