Artist Julian Berthier made this sculpture. It looks like a capsizing boat, but there's no hull beneath the waterline:
the floating sculpture is made from a large sailboat that has been modified to appear as if it is capsizing. despite its battered appearance the boat is fully functional and able to move around thanks to a built-in motor. to create the piece a 6.5 meter yacht was cut in half and a new keel was added to allow the boat to remain upright in the sinking position. since its construction berthier has taken the boat out on numerous trips inside harbours like canary wharf in london and in normandy, france.
