The

1981 Newport 30 is a classic fiberglass masthead sloop designed by Gary Mull and built by Capital Yachts Inc. as a capable, roomy coastal cruiser-racer. [1, 2, 3]

Specifications

• Length Overall (LOA): 30.0 feet (9.14 m)

• Beam (Width): 10.7 feet (3.25 m)

• Draft: ~4.75 to 4.9 feet (fin keel) or a shoal draft option (~3.75 ft)

• Displacement: 8,000 lbs (3,629 kg)

• Ballast: 2,600 lbs (lead)

• Fuel Capacity: 20 U.S. gallons (76 L)

• Water Capacity: 60 U.S. gallons (227 L)

Hull and Deck Design

• Construction: Solid hand-laid fiberglass (GRP) hull with a high-profile coachroof that maximizes interior volume. [1, 2]

• Keel and Rudder: Features Gary Mull’s characteristic scimitar-shaped fin keel and balanced spade rudder, offering responsive tracking and predictable upwind performance. [1, 2, 3]

• Cockpit: Tiller steering was standard for this era (though many have been retrofitted with wheel steering), featuring comfortable bench seating, primary winches outboard, and decent cabin-top winch placement for halyards.

Interior Accommodations

• Headroom: Impressive stand-up headroom reaching nearly 6 feet 4 inches in the main cabin due to the raised coachroof design. [1]

• Forward V-Berth: Comfortable double V-berth with storage drawers, shelving, and immediate access to an enclosed marine head. [1, 2]

• Main Saloon: Features a bulkhead-mounted folding table flanked by opposing settees (the port side often converting to a pull-out double berth). [1, 2]

• Aft / Navigation Area: Includes a functional quarter-berth/pilot berth extending under the cockpit, a slide-out navigation station with chart storage, and an aft galley equipped with a sink, icebox, and space for a stove. [1, 2, 3, 4]

On the Water

The 1981 Newport 30 is well-regarded as a forgiving and stable club racer or weekend family cruiser. It handles light-to-moderate air gracefully and offers a spacious below-deck layout that punches well above its 30-foot overall length. [1, 2, 3]

The Universal M-20 (often designated as the M3-20 series) is a 3-cylinder, freshwater heat-exchanger-cooled marine diesel engine rated at approximately 18 to 20 horsepower at 3,600 RPM. [1, 2]Engine Specifications

• Base Block: Marinized 3-cylinder Kubota tractor diesel engine.

• Horsepower: ~18–20 HP at 3,600 RPM.

• Displacement: ~719 cc to 85 cc-class / 43.8 cu. in.

• Cooling System: Fresh-water cooled via a heat exchanger with a belt-driven raw-water pump.

• Electrical System: 12-volt system, typically equipped with a ~51-amp alternator and glow plugs for cold starting.

• Transmission: Usually paired with a mechanical or hydraulic reduction gear (such as a Hurth or ZF gear with around a 2:1 reduction ratio). [1, 2, 3, 4, 5]

Context in a 1981 Newport 30

• Original Equipment vs. Repower: The 1981 Newport 30 (Phase I/II) originally rolled out of the factory predominantly with the gasoline-powered Universal Atomic 4. [1]

• Installation: Because the Universal M-series diesels were specifically engineered with compact dimensions to serve as direct drop-in replacements for the Atomic 4, many older Newport 30s have been retrofitted or repowered with an M-20 or similar small Universal diesel over the decades. [1]

• Performance: An 18–20 HP diesel pushes the ~7,500 to 8,500-lb displacement hull efficiently at a cruising speed of around 5 to 6 knots, burning roughly 0.4 gallons of fuel per hour under normal loads. [1, 2, 3, 4]
