I wonder how many routes make that possible - or even more. With planning and a longer day, we could probably have made it five on this trip.
On Monday August 1st, we left the bottom of Hanwell at eight o'clock. At twenty past nine we were on the visitor moorings at Brentford waiting for our passage through the lock.
At ten thirty we were through the gauging lock...
And at quarter to one we left CRT waters and were on the Port of London Authority tidal Thames.
Through Richmond bridge and over the weir
We made it to Weybridge dead on half past five,
A few more hours would have taken us to the Basingstoke Canal and a fifth navigation authority, but for us that had to wait a few more days.
Can anyone suggest other trips taking in as many or more different navigation authorities in a space of, say, twelve hours?
