The HAVOC National Twelve (1975)

The HAVOC National Twelve was a joint business venture between Patrick Blake and myself. It may seem strange that we decided on a National Twelve project, instead of a Merlin Rocket, but I think we felt it would be much easier to produce a GRP hull under the more liberal National 12 construction rules.

I made the plug for the Havoc hull mould in my dining room. The mouldings were made by Lloyd Channing Associates of Nottingham. Only a few were built.
