This is the website of Keith Callaghan, trading as CALLAGHAN DESIGN. I have been designing and building racing dinghies and small yachts for nearly 60 years. My high performance sailing dinghies include the state of the art Merlin Rocket HAZARDOUS series and the HADRON singlehander series, including the HADRON H2 carbon composite singlehander. My small yacht designs have been developed for ease of use, light weight and excellent performance. All but the largest are easy to tow behind a 2 litre vehicle.

This website gives details of all my designs but please see my popular YOUTUBE CHANNEL for videos of many of them in action. The channel has already received more than 130,000 hits.

JORDAN BOATS can provide a complete set of plywood components, cut to exact shape and size, for any of my designs. Please contact me or Alec Jordan if you want to know more.


My designs all have the following features: full size berths, full sitting headroom, galley space, large self-draining cockpit, 'inboard' well for outboard motor, ballasted centreboard fully enclosed in hull when raised, true trailerability, and last but not least - excellent sailing performance.


My design career started with racing dinghies: mainly National Merlin/Rockets (about 110 of them were built), but also National Twelves, International 14s, and the Harrier single-hander. The design portfolio now includes several singlehanders and the latest HAZARDOUS series of Merlin Rockets.
