Looking ahead to next season, it might be useful to identify how many boats could join a weekend meet at different locations.

Assuming the meet is on the non-tidal Thames, where is the furthest place up and downstream you could sensibly reach in a day from your normal mooring place?

I will correlate replies on a map so that we can see what venues would be most likely to attract the maximum number of participants.

To start the ball rolling, I could reach (up)Marlow or (down)Teddington.
