Combining state-of-the-art systems design and engineering, select materials and components, and vigilant manufacturing controls, Island Packet Yachts offer an unmatched combination of safety seakeeping, comfort and performance; the venerable IP 31 is the boat that put Island Packet on the map, and it's one of the best conceived and executed vessels of this size we've ever seen.
This particular example is bristol inside and out; never cruised, she shows YEARS newer that her actual age. She's the only IP 31 currently for sale on the west coast and is a must see for anyone in the market for a boat of this type.

Accommodations and Layout
Master cabin forward with big 6' 6 V-berth with insert plus hanging locker,private access to head with shower.
Aft to spacious main salon with dinette that folds up against bulkhead and L shaped settee
The aft cabin quickly converts from a nav area with a chart table which folds down out of the way to access the quarterberth; the nav table then cleverly folds up to the ceiling so, with the pocket door closed, there is complete privacy.
Note interior looks as new, 16,000 BTU MarineAir reverse cycle heat/air, upgraded lighting, beautiful joinery, 6' 3 headroom.
Twin stainless steel sinks with hot/cold pressure water (six gal. hot water heater, engine and AC fired; new fresh water pump in 2012), large (11 cubic ft) heavily insulated icebox with Adler-Barber refrigeration, two burner propane gimbaled stove with oven. Jabsco manual pump toilet.
110V AC / 12V DC. Freedom 15 battery inverter/charger w/ Link 2000R system, four Lifeline AGM 6 volt batteries (2010), Lifeline AGM dedicated starter battery (2012), large frame 160 amp alternator.
Autohelm 3000 autopilot, Datamarine depth/speed/distance, Standard Horizon VHF at nav, handheld VHF radio, ship's clock and barometer, Jensen AM/FM/CD stereo.
Deck and Hull
Heavily laid up FRP hull with cored decks, full keel with cut away forefoot, encapsulated iron ballast and skeg hung rudder.
Note that the moderate displacement U-shaped hull form with long waterline, broad waterline beam, and 40% ballast ratio combined with ample sail area makes the IP31 an exceptionally powerful stiff sailing yacht that performs extremely well.
The design features large unobstructed deck and cabin top surfaces. The bow sprit platform is equipped with an anchor roller and deck pipes allowing ground tackle to be easily retrieved and stored. Always ready for immediate use.
Safe and secure deck work is ensured with raised bulwarks, non-skid and full length cabin top hand rails.
The roomy cockpit is over 7' long and can seat 8 adults in comfort. It features contoured seats with deep coaming backrests, large seat lockers, a cockpit ice box, coaming storage bins and a comfortable helm seat.
Sails and Rigging
Versatile cutter rig provides maximum sail handling versatility for a wide range of wind and sea conditions. 130% genoa on Harken roller furler (2006), self-tending staysail on roller furler, single spreader aluminum keel stepped mast and boom with full batten mainsail, 1x19 stainless steel standing rigging (replaced in 2008, at which time chainplates were rebidded), two Lewmar #40 two speed self-tailing winches, three Lewmar #7 single speed winches, all lines lead aft.
Boat US Review of the Island Packet 31
Introduced in 1983, this traditional design which features a sweeping sheerline, stubby bow, nearly vertical transom and considerable beam was a bit of a risk for Island Packet because many sailors have strong feelings, one way or the other, regarding the aesthetic appeal of traditional designs. However, the risk paid off in spades: The 31 established Island Packet's firm hold on this segment of the market and the company prospered during a time when many long time builders were forced to close their doors. The Island Packet 31 remained in production until 1989 when it was replaced by the Island Packet 32. In all, 265 boats were sold many in the Chesapeake Bay area.
Although this model is known as the Island Packet 31, the length on deck is actually 30' 7". As is the case with all Island Packet monohulls, a bow pulpit extends the over all length which, for the 31, is 34' 4". Beam is considerable at 11' 6" and, in plan view, it is apparent the point of maximum beam is forward of amidships. This "Cod's Head" style was typical of late 19th and early 20th century designs but is not common on modern designs. The Island Packet 32, which replaced the 31, shows a much more standard distribution of volume for a modern vessel and is likely a better performer. Standard draft of this full keel design is only 4' and, for those who are really into gunkholing, about ten percent of the 31's were built with centerboards drawing only 3' with the board up. Displacement is 11,000 lbs. and ballast is indicated at 4,500 lbs for both the centerboard and standard draft models.
Construction of the hull of the 31 is a solid laminate of fiberglass cloth and polyester resin. There is considerable use of molded fiberglass liners, which obstructs access to many areas of the boat and complicates repairs. However, with proper engineering and adequate quality control during construction, this is a strong and cost effective method of production. Island Packet does a good job of both and I have yet to find any significant structural failure of an Island Packet hull that resulted from poor design or workmanship. A unique feature of all Island Packet boats is their method of deck construction. Instead of using balsa or foam core material, Island Packet use their own "Polycore" which is a mixture of resin fillers. I have no information on how this compares in weight and strength to well documented and more traditional core materials but, again, I have yet to run across any serious delaminations or failures. Ballast is encapsulated iron and centerboards have a small amount of lead weight that seems more intended to keep the board down than have any significant effect on stability.
For the first year and a half or so auxiliary power was provided a 22 hp Yanmar. This was updated to a 27 hp Yanmar the second year and was more a decision of the engine manufacturer than the builder. Yanmar replaced their 3GM22 model with the 3GM30 model in 1985 which was essentially the same engine optimized for a little more horsepower. Either engine should provide adequate power under most condition although the 27 hp model will provide a little more push through strong currents or choppy seas.
Make no mistake about it, the Island Packet 31 is a cruising sailboat. Although predictably, under certain conditions, her performance can be quite respectable. The 31 was offered as a sloop or with a double headsail arrangement commonly called a cutter. This is more accurately a double-headsail sloop but this is nit picking. For most coastal cruising conditions the sloop would be the preferred rig on this sized boat but, perhaps for aesthetic reasons, most were rigged with the double headsail arrangement.
It would be impossible to design a boat with shallow draft, a full keel, considerable volume forward and have it sail efficiently to weather by modern standards. In this regard the IP 31 is no surprise. However, the sail area/displacement ratio of 17.2 provides adequate power and the considerable beam provides initial stability to carry sail which translates to quite good reaching performance when the wind picks up to 12+ knots. Down wind performance is hampered by considerable wetted surface. Although, if the wind is above 10 knots true, performance is acceptable and, when it really blows, the boat tracks and handles nicely.
The accommodations and livability of the IP 31 may be matched but can't be beat on a 31' boat. The arrangement is fairly straightforward with V-berth forward followed by a starboard side head, opposing settees in the main saloon, port side galley, starboard side quarter berth and navigation station. The 11' 6" maximum beam and wide waterline beam allow accommodations to be pushed outboard providing plenty of livable space. The galley is U-shaped and is the size found on 35 to 38 footers. There is a clever arrangement for the quarter berth and navigation table which allows the chart table to be flipped up and a folding door to be extended to for an enclosed quarter berth cabin. Newer model boats offered a cockpit shower, stern rail gate with swim ladder and metal rather than plastic ports. All were nice improvements.
Island Packet 31's do not come cheep but, for coastal cruising and livability aboard a 31 footer, this is a tough one to beat. Prices reflect the popularity, solid construction and company reputation for customer support.
