An Stradag on Coniston Water November 2005

Fiona, Countess of Arran set the first officially acknowledged record of 50.825 mph in An Stradag in 1989. 

An Stradag had been on display in the Lakeland Motorboat Museum until it was bought by Henry Engelen early in 2005. The boat was reworked and updated at Henwood & Dean's boatyard near Henley by a team of EBA business members. 

 
Thames Electric Launch Company installed the controllers and electrical systems, Cedric Lynch supplied four new 25kW motors manufactured in India by Agni Motors, each controlled by a 1231C Mosfet controller from Curtis Instruments.  The Exide AS45R 12 volt batteries were provided by Chloride Motive Power An Stradag, piloted by Helen Loney, increased the speed for battery powered electric boats on Coniston Water in November 2005. She clocked 70.610 mph during the south run and 65.561 mph on the return trip to record an average of 68.09 mph.

Solar Power

July 1997 EBA member Malcolm Moss made a successful
Solar Powered Crossing of the English Channel in S.B. Collinda
and was awarded a special trophy by the EBA to mark his achievement.

The voyage between Dover and Calais was undertaken under solar power alone when weather conditions were broken cloud followed by hazy sunshine.  An average speed of 6.3 kph (3.9 mph) was established for the 24.47 mile crossing in 6hrs 15 minutes

 August 2000 Cedric Lynch set a time for a solar powered boat for the Guinness Book of Records. The official record was established on the River Arun at Littlehampton over a 50m stretch of river. The average speed for traveling the measured course in both directions was 5.48 kph and optimum time was achieved with Cedric at the helm and Cllr. John Richardson as a passenger.

Cedric used a Canadian style canoe to which two photovoltaic panels were mounted

There were no batteries or any other source of power in the boat.  The craft was designed and constructed by Cedric Lynch, solar panels were connected via an electronic speed control unit to a prototype Lynch electric motor coupled via a reduction gearbox mounted at the stern to a modified two bladed model aircraft propeller.

June 2003  EBA members Paul and Ulrike Lynn made the first-ever solar-powered voyage along the entire non-tidal River Thames from Lechlade to London (124 miles, 43 locks) in their 21ft home-built catamaran “Solar Flair”. Total cruise time was 37 hours spread over 11 days of travel.
