Westerly launched the Regatta 330 in 1993, when it divided its boats among three ranges: Oceans, Regattas, and Victorias. A remodelled Storm 33, the Regatta 330 carried forward that boat’s hull lineage within the performance-oriented Regatta family. Production continued through 1998, but only fifteen hulls were recorded, making it a scarce and distinctive entry in the Dubois catalogue.
Design and Construction
The Regatta 330 is 33.17 feet overall, with a 30.02-foot waterline and an 11.19-foot beam. She has a fin keel, a spade rudder, and a draft of 5.5 feet. Both the hull and deck are solid fiberglass.
Displacement is 11,310 pounds, including 4,210 pounds of iron ballast. That gives a ballast-to-displacement ratio of 37.22 percent and a displacement-to-length ratio of 186.63. These figures place her firmly among moderate-displacement cruiser-racers rather than at the lightweight end of the spectrum.
A capsize screening ratio of 1.99 and a comfort ratio of 22.63 point to a boat designed with offshore stability in mind, rather than for outright speed alone. Her sail-area-to-displacement ratio of 16.51 indicates a moderately powered rig suited to all-around cruising.
Rig, Sail Plan, and Handling
The Regatta 330 is a masthead sloop carrying 520 square feet of sail area. Period specifications list the jib and genoa sheets at 10.1 meters (33.2 feet) with a 12 mm (1/2 inch) diameter, the mainsheet at 25.3 meters (82.9 feet), also in 12 mm, and the spinnaker sheets at 22.2 meters (73.0 feet) in the same 12 mm size.
Using the same diameter for all three simplifies spare-line selection and deck organization. The generous mainsheet length reflects the traveler geometry needed to trim a 520-square-foot main effectively.
Her calculated hull speed is 7.34 knots, consistent with the 30.02-foot waterline and giving a predictable performance envelope under sail.
Machinery, Tankage, and Accommodation
A single 19-horsepower Volvo Penta MD2020 diesel provides auxiliary power. The builder specified tankage of 40 gallons for fresh water and 21 gallons for diesel. That fuel capacity is modest and constrains longer motoring legs.
The 11.19-foot beam and 33-foot hull provide the footprint for a conventional aft-cockpit cruising interior in the style of mid-1990s Westerlys.
Verdict
The Westerly Regatta 330 is a low-production Dubois design that repackages the Storm 33 hull within the Regatta range’s performance-cruiser ethos. She combines solid, single-skin fiberglass construction with a practical rig and moderate-displacement proportions. Her statistical measures point to stability for coastal and offshore use rather than an emphasis on speed alone.
Rarity is the main complication. With only fifteen boats built, a buyer must weigh the limited availability of hull-specific spare parts and shared owner knowledge against the appeal of a thoughtfully engineered late-Westerly design.
Pros
- Remodelled Storm 33 lineage under Ed Dubois’s design hand
- Solid fiberglass hull and deck
- Moderate-displacement, stable proportions, including 37.22% ballast and a 1.99 capsize screening ratio
- Uniform 12 mm sheet diameters simplify gear replacement
Cons
- Only fifteen built, limiting used-market availability and shared owner knowledge
- Modest 21-gallon fuel capacity constrains longer motoring legs
