Barry Sullivan's fireboat, built in 1969 from the aero kit. This was his first boat and was given to his son, then brought back and refurbished. it was then given to his grandson and brought back again for refurbishment last year.
Dusseldorf that's recently been finished by Dave Gibson. He has still got a few bugs to Iron out on the electrics such as rudder and motor twitches.
He also thinks it seems to be a little under powered and noisy (however his last build was a motor torpedo boat) so it may just be a little getting used to.
