It’s a rubber duck with a baked bean tin mashed into it. The baked bean tin rotates to indicate which side of the craft the broadsides are facing. The crew have ducks for heads - think Ratatouille if it was a horror film about ducks.
The creation of this monstrosity was targeting a Scabz event being run by Salute Fringe. It was a gruesome affair, as desperate rival steamers blasted and shunted their way around the tables of Bad Moon Cafe.
A lovely event, with lovely folk in attendance! It will always be Eel Day in my heart.
