This might be of interest to south east UK spotters
I noticed that there were a couple of different tugs working Felixstowe the other day, the SVITZER HAVEN & SVITZER SKY both normally found in the Bristol Channel and South Wales, I'm also told that the SVITZER CALDEY has also been seen in the area.
And at Lowestoft, the 2010 built dredger UKD ORKA is working.
