Lifting out from the building shed of Alnmaritec's facility at Wimbourne Quay, ironically on the site of the former shipyard on 8th May 2015

See her underway at: https://www.youtube.com/watch?v=wrPYve8dClw

But what is she? Some sort of fishing vessel?

'Offshore Shellfish' on the notice is a clue?

And the three gatling guns on the fore deck are for shooting down flying whelks?

It's a sort of hippo shape and colour, maybe it's a stealth hippo hunter ......

And no Hippo's were harmed during her construction
