I have booked the scrubbing posts for Sunday 31st May. High water on Sunday is 05.14, If I lock-out at 06.00 and arrive at the posts by 07.00 will there be enough water? The tidal charts show approx 4.5 metres at 07.00 and I draw about 1.2 metres. It's my first time on the posts so any advice would be much appreciated.
