Notes

Before Hurley Marine went out of business the moulds were sold to Russell Curnow of Penzance, Cornwall who continued to build them up until about 1979. The moulds were then bought by Varne Yachts of Nottingham who were later taken over by Weston Boats who then went out of business in 1986. Over 900 H18s were built altogether.
