We left Kinver this morning and cruised down to Cookley - all of two hours.
The rains over the past few days have washed away part of the towpath in Kinver.
At Cookley there is a very short tunnel.
Using the BW calculations: 3 minutes to cruise 59 metres produces an interesting result. Assume the boat is 21m long that means 80m to pass through the tunnel in 3mins which equates to 1mph.
Perhaps BW calculations are based on legging it through.
We moored opposite the park homes at Austcliffe where Gecko tried to keep a low profile.
