Early start to go through Blisworth tunnel as we wanted to get ahead of two working boats to avoid the fumes, even though you can pass in the tunnel we were lucky not to have to pass anyone. It took us 35 minutes to get through to Blisworth, not too bad for the third longest tunnel. We stopped off at Gayton Marina as we were booked in for our engine to be serviced, they are based on the Northampton arm so we had a short cruise then on to the winding hole just before the locks before heading back onto the Grand Union. We would have liked to have gone onto the River Nene but the water levels are so low on the lock chambers it wasn’t advisable.
