In 1987 the Pearson 31-2 went into production as a new design by Bill Shaw
Bill Shaw said; "With ample sail area proportioned into a powerful rig, and a contemporary hull with modern appendages, the new P31 has already shown her abilities as a fast boat". It was produced until 1991 and available with a standard or shoal draft wing keel. Hull number 268 was the last boat out of the Portsmouth factory before closing for good in 1991.
In 1996 Cal-Pearson re-introduced the P31 during a short lived revival of the Pearson brand.

Today we hear a lot about contemporary and traditional values as they apply to the many facets of our lifestyles. When these concepts are applied to yacht design, I have never considered them to be mutually exclusive.
On the traditional side, the basic principles of hydrodynamics, aerodynamics, and human engineering continue to apply. Regardless of how you use your boat, the back to basics approach used by our designers insures you, the owner, that your boat will perform over a wide range of conditions and still provide engineered comfort even at the dock.
The contemporary ingredient in the new P31 manifests itself in the form of a new elliptical keel in the standard version, or an optional wing keel that provides shallower draft. The P31's interior arrangement is traditional, but with a few new twists. Aft there is a huge open quarterberth that extends under the cockpit, spacious galley with unusually good storage to port, and a clever combination ice box/chart table to starboard. In the salon there is an offset centerline table which makes moving fore 'n aft easier, a spacious dinette, which converts to a double berth without using the table, and again, plenty of storage. Further forward, there is a roomy head with shower, and still further forward an exceptionally spacious V-berth area.
On deck, the basic elements composed of cockpit, cabin trunk, etc., are still there naturally, but rather than simply translating wooden shapes with hard edges into fiberglass form, as so many others do, we have exploited the virtues of fiberglass with contoured seats that fit the human form and deck styling that fits the wind.
Equally important to the cruiser or racer is the boat as a performer. With ample sail area proportioned into a powerful rig, and a contemporary hull with modern appendages, the new P31 has already shown her abilities as a fast boat. A very important factor even for those of us who never race. Come Sail With Us...

Bill Crain's 1991 P31-2 (#268) was the last boat out of the factory before closing for good in 1991. He made a digital copy of his owners manual and contributed it for sharing on the web. The manual has a fair amount of detail for the 31-2 and there is a fair amount of cross over for other Pearson boats on the line at the end of production. The models include: P27, P28-2, P33-2, P34-2, P35-2, P36-2, P37-2, P39-2, P38.
