Stayed put in the boatyard overnight on Tuesday, so they could fit the Sterling AB12160 first thing. In the end, everyone was a bit late, but it got done. Much bigger job than the Sterling bumph and website suggest – mainly in relation to creating and siting the cables.
Moved up above Wardle lock again mid-afternoon. Ran the engine in the evening, though after being on a hook-up this probably wasn't really necessary.
0.3 miles, 1 lock, 2 hours engine.
