Jehol, a 1970s Westerly Centaur – one of the most popular British-made yachts – is a boat that Green is in the process of tackling. “She has changed hands for £1 four times, always to people with a dream and the best intentions,” he says. “But life takes over.”

Wood and steel hulls in old boats can be managed relatively easily through established recycling routes, as can other metal and wood components on a boat. This is not the case for FRP, which doesn’t easily decompose, though it does physically break down over time. Research undertaken at the University of Brighton has shown that boats made of FRP which are left in the water release microscopic fibres.

“…She was built at a time when people wanted adventure on the water, rather than a chilled Chardonnay tied to a pontoon.”

There are an estimated six million boats in the EU alone, 95% of which are made of GRP. Every year, around 1-2% (60,000-120,000) of these boats reach the end of their useful life. Of these, only 2,000 are recycled, while 6,000-9,000 are abandoned.
