Any thoughts on the up river passage from Ramsgate using the 4 Fathom Channel with 1 metre draft? Have not done this passage before but looks a bit tight around Hook Spit and the Gant?
Done it many times, I also draw a metre. Never had less than 3 metres under us. I have done the four fathoms channel at all states of the tide.
You should not have a problem if you stick to the bouyed channel.
