I was told to go fast – so I did

Kidderminster Trip Day 3 – a technical perspective

Travelling through the 1.66 mile long Harecastle tunnel was an experience.  We had been warned to go quickly by the attendant, and that most people with new boats go too slowly and end up zigzagging, hitting the walls and scratching their paint.  I took the man seriously and took my first opportunity to see just how much power we have from out electric motor tried to see just how much power our boat has, my first opportunity.

We travelled through the tunnel in exactly 30 minutes at 580RPM, at 147 amps, (7.5kW).  In total we used 73.5AH (3.7kW hrs) traveling through the tunnel at an average speed of 3.3MPH.  That is the equivalent of less than 1.25 litres of diesel or 89p at the price we pay.

I was pleased with this because we were told that the normal time to do the tunnel is 40 minutes and we did it in 30 minutes.  Apparently one boat the day before 1 hour 15 minutes.

We travelled from the tunnel to Stoke at high speed because the canals were wide, deep and with very few boats allowing me to test how well the boat performed in wider canals, at higher speed.  The boat handled well and I had plenty of extra power in reserve.
