Rub a dub dub, two men in a tub,
And I firmly believe they’re daft.
Not metal or wood, as a sane man should,
They used chocolate to build their craft.
There's a video of the launch on BBC, but I won't link to it because you have to watch a 29 second commercial, just to see 28 seconds of break the champagne bottle and dump the boat in the water, with no real information.
Anyway, one of the two guys owns a chain of chocolate stores, and according to
Arbroath, won a bet by building it.
It's flat bottomed, tipsy as hell, and neither the engine nor sail are chocolate.
