I have set up a webcam that shows a live image of the Spitbank Fort just outside of Portsmouth harbour. People might find this handy if they want to see what the conditions are like before they set out. It updates every 30 seconds, 24 hours a day.

If it doesn't work, please let me know - I've had a couple of teething problems so far but I think they are sorted now.
Edit: having just put this up it appears to have stopped working. I changed hosting companies yesterday and this appears to be to problem. If it doesn't work when you click try again later - I will attempt to sort the problem.
