Our progress is based on a 6 hour day and worked out by the excellent CanalplanAC web based program. So today we are supposed to be at Milepost 74 to Braunston, but we don’t know where that is exactly. My best guess is here. Leaving Cowley after an excellent meal At the Malt Shovel last evening, we did Cowley Lock and stopped for water before proceeding on. We are now expecting guests on Saturday, staying over till Sunday afternoon. So the 6 hour day guides as to where and modified by practical considerations. It looks like Berkhamsted. Tomorrow should be Apsley where we will be able to stock up on victuals for the weekend. Moving on after our water stop it was interesting to note changes in the environment since the time we were based in Harefield. In particular the offside below Dunham Deep Lock is now an overgrown jungle. The towpath side is a “boatyard” and the lock landing seems to have been consumed within that, so using the offside landing does not look pretty. The bottom gates of Denham Deep look like the hanging gardens of Babylon. We needed to access Harefield Marina for an item of chandlery, but the wharf was occupied, the wind was troublesome and a boat emerging from the lock made an attempt at reversing alongside the moored boat impractical, so we went into the lock and did a very slow ascent while I rushed round to the chandlery by road. After that a brief stop at Tesco because it is so convenient, a difficult time in the wind with no convenient mooring possibility waiting for Batchworth Lock. Finally we moored up above Lot Mead.
