This from designer, Ted Brewer: "The yacht is a grp version of the custom, wood, 'Black Velvet' (see her on under Sail - Wood.). The first fibreglass versions were built by Cape North in Hong Kong, in the mid '70s, as the Cape North 43. Later a Philippine firm obtained the molds and produced a few.
The CN 43s were good boats and several did well in prestigious ocean races in the '70s and '80s, including a China Sea Race fro HK to Manila. Others survived some severe storms in the Atlantic on their way to Britain from the builders. The CN 43s seem to have been well built, under British management, but I have no idea of the quality of their Philippine sisterships."
