Design
The M34 is a racing keelboat, built predominantly of fibreglass with a sandwiched core. It has a 7/8 fractional sloop rig with a carbon fibre keel-stepped mast and fixed bowsprit, and an aluminum boom. The mast has two sets of 20° swept spreaders. The hull has a plumb stem, a raised plumb transom, an internally mounted spade-type rudder controlled by a tiller and a fin keel. It displaces 5,952 lb (2,700 kg) and carries 2,315 lb (1,050 kg) of lead ballast.[1][2]
The boat has a draft of 8.16 ft (2.49 m) with the standard keel. The keel can be partially raised for ground transportation and gives a draft of 5.92 ft (1.80 m) with it raised.[1][2]
The boat is fitted with a Swedish Volvo diesel engine of 20 hp (15 kW) with a saildrive for docking and manoeuvring, supplied by a fuel tank with a capacity of 13.2 U.S. gallons (50 L; 11.0 imp gal).[1][2]
The design has sleeping accommodation for four people, in two cabins. The below decks headroom is 67 in (170 cm)[2]
For sailing downwind the design may be equipped with an asymmetrical spinnaker of 1,399 sq ft (130.0 m2). It has a hull speed of 7.71 kn (14.28 km/h).[2]
Operational history
The boat served as the one-design class for the Tour de France à la voile from 2011 to 2014.[7][8]
