What do you call

This strange craft?

[Maggiemae]

Perhaps its a dredge or maybe just a ferry transporting machinery! Love the seawater feel!

Great capture

[Susan Wakely]

Industrial looking Tug.

[Dione Giorgio]

A mobile enthusiast delight. Why? Because all the members of the crew are playing with their mobiles. Seriously this could be a converted barge capable to do simple drenching works or salvaging wrecks.

@maggiemae I see it around a bit. @sangwann I think you have it there. I often see it next to the retired Medina Car ferry from Cowes. @bkbinthecity @wakelys Thank you everybody for the comments.
