I am currently in England on holiday and had the chance to do some tidal sailing on a friend's boat. He keeps it in Saltfleet, a tiny drying harbour on the East Coast of England. It's a drying mooring, meaning there's no water at all during low tide.
Unfortunately the boat even sat at an uncomfortable angle, so we had to sleep in the club house, or one of us would have fallen out of the bunk.
Waiting for the tide to come in we ended up in a pub. Bingo,
Sunrise occured at 3.30am. Don't ask me why I was awake. I just was.
The tide started to come in during the morning.
Not enough yet...
Finally
And sailing.
