Notes

In 1979 Hughes Boat Works acquired the molds and built the COLUMBIA 8.7 for a while in Ontario, Canada. When Hughes went into receivership in 1982, the molds ended up with Aura Yachts where they were sold in varying states of completion. In 1986 Hughes took the line back again until their factory was destroyed by fire.
