I've been intrigued by the Yachting World Diamond ever since I saw Black Diamond on Dylan Winter's video diary "Keep Turning Left".
Back in 1960 the editors of yachting world sought ideas for the design of a new keel boat. The requirements were that it be reasonably priced, yet have high performance suitable for national and international racing. The details of how he became involved are not clear, but Jack Holt a dinghy designer more famous for his GP 14, Cadet, Enterprise and Mirror dinghy, used his small boat experience to create a revolutionary 9 meter plywood keel boat - which some describe as a dinghy with a keel.
The Yachting World Keel Boat was first shown at the 1961 boat show to great interest, and one went on to win the 250 boat strong open class in a race around the Isle of Wight in that year.
The boat was launched in Australia on Pittwater in 1962 and has a strong following right up to the present day under the Yachting World Diamond Association of Australia, the name being changed to Diamond in 1967. Since the 1980's the boats have also been made in fibreglass.
Plans are available for the Australian Association and the boat can be home built within the class rules. Although I don't especially want to build one, I was interested to understand the hull form and learn more about this fasinating boat.
Imagine my surprise the other day, I was looking through my collection of old sailing books when I found these lines plans in a volume "Make Sail" by Peter Heaton.
