Unwanted vessels left to decay release fibreglass shards into the water, harming marine life. Steve Green – with his trusty van Cecil – is determined to clean things up

Steve Green, a boat engineer from Cornwall, was pulled over by the police just before Christmas. He was driving a decrepit-looking VW campervan and towing an even more dilapidated yacht up to Truro. He hadn’t broken any laws, but he admits that Cecil the campervan, which runs on donated chip oil from local pubs and has a crane and a winch on the front, “wasn’t quite what VW intended”.

Green (and Cecil) are on a mission to rid the beautiful hidden creeks of Cornwall’s Helford and Fal rivers of 166 abandoned fibreglass yachts, which are leaking plastic and toxins into the predominantly marine waters. Marine biologists have likened the thousands of shards of fibreglass they have found embedded in the flesh of sea-creatures in areas with wrecks such as these to asbestos, a substance known to have a noxious effect on humans.
