From the look on the tides I would say Beachies would have plenty of water from about 1130 onwards which is when I would expect the wind to come in. I sailed Sandgate the other week and couldn't believe how many Jellies there were. Almost as many as kitesurfers

. Hopefully there will be less of both a little further north. The drive is not that bad, and it's certainly worth it if the conditions are right.
