Morning All,
Apologies if this has been discussed before but I couldn’t find it on the search:
I have a 60x11 Piper Widebeam with a 60hp Beta in a Marina on the Thames near Bray. I am new to boating having only had 1.5-2 weeks cruising since I purchased the boat this year.
Q. Is there a way of working out the speed of the river? I can’t find any useful websites with the info. I am really only interested in non-tidal Thames, particularly between Henley abs Shepperton.
We are on yellow boards (increasing) and have been all week. The river levels themselves are not a problem, I just want to make sure if I go out I can get back up stream.
I have tried measuring the speed of floatsam by walking at pace with it using a gps. It’s around 2.5-2.8 mph (at least on the surface). I have been told she will make 3.8-4.5 mph. In theory it seems fine as I only want to go 1 mile downstream to empty the holding tank before winter and fuel up.
Any advice would be appreciated. I am aware that going out on red boards may invalidate insurance.
Thank you!
