Hi All

I am taking a trip to St Kats in August and will pass Richmond about 7am high tide being about 5am but cant get into st Kats untill 14.40 , we plan a little venture out past the Barrier but will still have a few hours to kill , last time we did it we lost and engine under tower bridge and had to hover around tower bridge on one , not fun. Any ideas for a spot to moor up for a couple of hours downstream of Richmond preferable with breakfast or lunch but doesn't have to?
We we were thinking Chelsea Harbour pier?
