Design and Construction
Mull carried the Newport 30’s DNA into a more modern hull rather than starting with a clean sheet. The Newport 31 is built predominantly of fiberglass, with a fixed fin keel and an internally mounted, spade-type rudder. Buyers who prioritized gunkholing over maximum upwind bite could choose an optional shoal-draft keel.
Capital Yachts was a California-based builder co-founded in 1971 by Jon Williams and Bill Smith after they acquired the Newport tooling from Elgin National Industries. It produced the Newport 31 under the Lindsay Plastics/Capital Yachts Inc. brand beginning in 1987. The design is now out of production, though no final production year is stated.
Rig and Performance
The Newport 31 carries a masthead sloop rig, the same general arrangement used on the Newport 30 but tuned here for a slightly larger sail plan. Sail area is 447 square feet, while displacement is 8,500 pounds. Its sail-area-to-displacement ratio of 17.17 puts it in the moderate-performance range rather than the featherweight-racer category.
The average PHRF racing handicap is 180, with both the recorded high and low also at 180. That tightly clustered rating indicates consistent hull and rig configurations across the surveyed boats rather than wide owner-driven variation.
The boat carries 2,600 pounds of lead ballast, giving it a ballast-to-displacement ratio of 30.59. This provides a stability profile suited to coastal cruising with occasional club-racing ambitions.
Accommodations and Intended Use
Classified plainly as a small recreational keelboat, the Newport 31 was conceived for American coastal sailors who wanted a step up from the smaller Newport models without committing to a dedicated bluewater hull. Its 10.5-foot beam and 5.16-foot standard-draft fin keel give it a roomy yet manageable footprint at the dock.
Mull’s development of the 1968 Newport 30 into this 1987 iteration suggests a refinement of interior volume and topside aesthetics rather than a clean-sheet redesign. The result fits squarely into the practical cruiser-racer lineage.
Verdict
The Newport 31 is a competent, Mull-designed evolution of the Newport 30. Its fiberglass construction, fin keel, spade rudder, moderate performance ratios, and tightly clustered PHRF rating of 180 define it as a stable, predictable coastal cruiser-racer rather than a specialist.
Pros
- Gary Mull design lineage derived from the proven Newport 30
- Tightly clustered PHRF rating of 180, indicating consistent class performance
- Optional shoal-draft keel for varied cruising grounds
- Lead ballast and a moderate 30.59 ballast-to-displacement ratio
Cons
- No stated production-end year beyond its being out of production
- Lacks the specialized offshore credentials of larger Mull designs
