This has been an interesting month because we have spent the past 4 weeks cruising the Thames going both up-stream and down-stream.
The boat is more efficient on a river because of the greater depth and width of water, so we use less power and go faster.
An added bonus on the Thames is that there are moorings with charging points. So we’ve been able to charge from shore power, topped up each day from our solar panels, so have not used our on board generator all month.
We charged the battery at St. Johns lock ( Lechlade) at their electric charging point and then went for three weeks before charging again at Sandford lock (south of Oxford). We could have gone another 4 or 5 days before charging, but we had heard that the moorings at Goring lock were closed for resurfacing work, so we charged when we could.
Distance travelled – 73 miles
Hours cruising – 35 hours 12 minutes
Electricity used for propulsion – 40.46 KWhrs
Electricity from Solar panels – 150.97 KWhrs
Electricity used for cooking etc. 187.12 KWhrs
This means for May our average electricity used for propulsion was
0.55 KWhrs per mile
1.14 KWs per hour
We are often asked how far we can travel on one charge – over 3 weeks in May we travelled for 35 hours, covering 73 miles and did all our cooking from a single charge topped up daily from our solar panels.
