Pleasure Vessels

CNAC designs custom cruising sail boats constructed of marine Aluminum alloy. Current designs are specialising in Motor Sailers, which provide the cruising sailor with the best of both worlds. For those days when the wind is against you and you want to get to a particular destination for the week-end, just put the engine on and sit in the comfort of the large pilot house and relax. When the wind is in a favourable direction, un-furl the sails also from the comfort of the pilot house, and scoot off over the horizon. On days where the wind is not quite enough, then the sails and engine can be used together. A self pitching propeller is supplied so that the most efficient pitch is developed to provide the thrust necessary to drive the boat and produce the greatest fuel ecconomy.

Designs are currently available for yachts upto 65 feet in length.Larger vessels can be designed to meet a cruisers specific needs.

MS55. A 55 foot motorsailer, capable of 1500 miles range under power, and considerably further if using sail assist. She is capable of cruising at hull speed (over 9 knots) under power with ample reserve for heading into weather. Off the wind, there is 1200 sq ft of sail to drive you along. Also provided is an off wind jib on a bowsprit, to provide additional horsepower when reaching or running. The yacht is constructed of marine grade aluminum for extended life. Bilge keels may be fitted if the boat is to be sailed in areas with large tidal fluctuations, so the boat can 'dry' out without having to shore the boat up. The bilge keels also allow easy winter storage, since no cradle is required.
