Yesterday, a London artist, Dmitri Galitzine, crossed the Solent, from Stokes Bay to Wootton Creek, in a giant pumpkin, complete with two outboard motors. The journey went so well that he sailed it back. I think that if I hadn't been stuck at work I'd have gone down to Wootton Creek to watch him sail in. Given the costs of and also the cutbacks to the Solent ferry services it would be tempting to rush out, get a giant pumpkin (or any other oversized vegetable), hollow it out and fix a couple of outboard engines to it...
Here's a link to a video of Dmitri's pumpkin Solent crossing.
