Reading the Instructions

Electric motor in place   © Paul Balmer 2007

Another visit to Fenny Compton today.  This time it was to see Emrhys and Ian from the Thames Electric Launch Company at work.

They had been working on the boat yesterday and today and had installed the “A” frame with the electric motor.

The photo shows it driving the pulley on the main prop shaft just astern of the diesel engine.  The bright blue circular thing is a centrifugal clutch which gives a soft start and the motor is almost invisible behind it.

When the electric motor is running the diesel engine is left in neutral and the electric motor drives the propeller through the belt. 

When the diesel engine is operating like a conventional boat the belt is driven but the blue centrifugal clutch is disengaged so the motor doesn’t turn.

Ian was completing the wiring today, while Emrhys was reading the instruction manual.  By this afternoon they had completed the wiring to the motor and the control system and I saw the motor running.

We were still in the paint tunnel so we could only try it briefly in forward gear but I was impressed.  With the engine cover open and no insulation in place I could hear Reading the instructions   © Paul Balmer 2007the motor running at maximum speed – but the noise of churning water from the propeller was louder still.

Once the cover is on the engine compartment and the sound insulation is in place it will be quieter than the noise of the water.

Lots of other work had been going on elsewhere on the boat.  Lots of fittings inside and lots more painting outside.

My next visit will be this Friday when the Boat Safety Scheme Examiner will (hopefully) issue our certificate.
