A lot of thought has gone into making sailing the Hadron H2 dinghy a pleasant and rewarding experience. Here are some of the main features, many of which are shared with the original Hadron (a multi-chine plywood boat):

  • The extremely light, performance-orientated but forgiving hull form and rig produces aH2 sailplan08 simplified 20160216 versatile, manageable dinghy which can be sailed on lake, river or sea, with good performance to windward and also offwind. An easy performance dinghy for novices. Excellent handling and exhilarating performance for experienced sailors.
  • A unique buoyancy configuration which ensures that the boat floats low in the water when on its side, thus facilitating righting. The boat floats on its side with the centreboard just clear of the water, and when righted retains a very modest amount, which can be evacuated via the self- bailers within a minute or so, even in light conditions.
  • The angled boom provides plenty of headroom for ease of tacking.
  • The large, deep cockpit area and ergonomic side decks provide a comfortable sitting out position. The central buoyancy compartment acts as a useful seat in light conditions. There is also a thwart for that purpose.
  • A centreboard is fitted – much more convenient than a dagger board, especially on a singlehander.
  • Rig controls are led to cockpit sides for easy adjustment afloat.
  • The flared hull, good freeboard and wide gunwhales minimise spray and keep the crew dry in all but the windiest conditions.
  • One of the biggest difference between the H2 and the original Hadron is the WEIGHT. The latest materials and techniques are used in the hull manufacture. The hull layup consists of carbon cloth with additional carbon/aramid reinforcement in areas liable to hardest use. The result is a hull which is extremely strong and long-lasting and significantly lighter.

The current OWNERS MANUAL is available here.

One of the major features of the H2 is its light weight. In order to achieve this, a minimum amount of gel coat is applied to the mouldings and no scrim layer is added between the carbon cloth and the gelcoat. This scrim lamination is designed to minimise ‘print through’ of the cloth weave, but adds significantly to the overall weight. Thus you may well see signs of ‘print through’ on the laminates. This is normal, and is a feature of the lightweight laminate structure.

The Hadron H2 has been tested by expert helms in winds up to Beaufort Force 6 (27 knots) and waves of up to 2 metres in height. However, sea state is dependent on many conditions, such as depth of water and tidal flow and it is an individual’s responsibility to sail in conditions in which he/she is competent.
