Design and Lineage
Camper & Nicholson commissioned Ron Holland to refine the existing Nicholson 303 hull, which became the basis for the 1/2 Ton design. The yard’s stated aim was to demonstrate the quality of its hulls in the IOR Half Tonner class. The resulting boat was conceived to dominate around the buoys rather than to wander.
With a length of 9.14 meters and a beam of 3.12 meters, the hull sits at the compact end of the category. Its 28-unit production run makes it a rare and deliberate special.
Construction and Specifications
The Nicholson 1/2 Ton has a solid fiberglass hull and deck, with a fin keel and spade rudder. Iron ballast of 3,086 pounds accounts for a substantial portion of its 5,750-pound displacement.
The numbers place the boat firmly in the light-displacement racer camp. Its ballast-displacement ratio is 51.85, its displacement-length ratio is 175.26, and its sail-area-to-displacement ratio is 27.42, underscoring the emphasis on powered-up speed.
Auxiliary power comes from a 12-horsepower Yanmar diesel. Fuel capacity is 12 gallons, while the water tank holds 20 gallons—minimal provisions consistent with the boat’s racing focus.
Rig and Handling
Period descriptions sum up the Nicholson 1/2 Ton as small, agile, and fast. Its fractional sloop rig carries 563 square feet of sail. With a 24.75-foot waterline, the boat has a theoretical hull speed of 6.67 knots, respectable for a 30-footer driven toward the windward mark.
The 2.26 capsize ratio and 15.74 comfort ratio also reflect its priorities. This is a buoy racer first, designed around performance rather than accommodation.
Accommodations
The available record provides no descriptive interior detail beyond the racer-cruiser envelope implied by the tankage and the silence of the sources. What can be stated is the constraint: 20 gallons of water and 12 gallons of fuel define a boat whose belowdecks plan served a racing crew rather than long-distance cruising. The 28-unit production count suggests few were ever fitted out for anything else.
The Verdict
The Nicholson 1/2 Ton is a concise statement of Camper & Nicholson’s late-1970s racing ambition: a Ron Holland design based on the Nicholson 303 hull, built in small numbers and aimed squarely at IOR buoy racing. It isn’t a cruiser’s cruiser, but as a small, agile, and fast half tonner, it remains a pure expression of its class.
Pros
- Ron Holland design based on the proven Nicholson 303 hull
- Light, agile racer with a strong sail-area-to-displacement ratio
- Rare and purposeful 28-unit production run
Cons
- Minimal tankage limits cruising range
- Race-first character, with little documented accommodation comfort
