Just been reading about Sulley's trip on the tidal Thames looks as though you had a great time. Like Emjay next week will be our first trip down to St Kats, were all booked in for the 23rd so looking froward to it immensely.
I am assuming subject to good conditons lack of interferance by rowing boats etc that Richmond lock to St Kats will be about 2.5hrs therefore say 3 would this be about right or am I way off the mark.
Enterprise6 - Yes you will be ok for timings, we took just over 2 hours to get back from St Kats to Teddington going with the tide and we did NOT exceed the speed limit at any point of time. I would say the tide gave us another 3-5 knots going at the same rpm we do on the upper Thames.
