Later - since I started writing this, I've been hand steering for a couple of hours because it's too much for the electric autopilot as well. The wind is strengthening and I think freeing us and we may have to drop the kite soon. I saw our first Portuguese Man 'o War (Bluebottle for the Australians) quite a big one, deep blue sac with crenellated fringe on the top edge and half moon curve so they drift with the prevailing wind. And a white bird settled on the water - unusual as most of them here are brown or black - orange beak, white head, black slashes around the eyes, grey flecks on top of the body and wings and two long straight white tail feathers - hard to judge their length but at least as long as the body. Not in the albatross book but somebody will know what it is.
Later still - we dropped it in time for a relaxed meeting with the Grindy - was building a nice fat quarter wave so time to douse and get the boat upright again - lost perhaps half a knot but the knuckles no longer grey.
Norm - thanks! Wish we had one of those machines.
