Design and Construction
The 40 uses a split underbody, with a ventral fin between the keel and a large skeg. The rudder mounts on the protective skeg, while the central fin separates the keel and skeg.
Displacement is 24,000 pounds, with 8,600 to 8,800 pounds of ballast depending on draft. A waterline length of 31 feet 3 inches produces a D/L ratio of 351, making this a heavy boat by any modern measure.
In a boats.com review, the tester described the 40 as comfortable and stiff at this weight. Its sections amidships are rounder than those of the deep-V, high-deadrise Valiant 42: the Crealock has 16 degrees of deadrise at station 5, compared with the Valiant’s 20. That’s still a lot by today’s standards, but it contributes to a high degree of positive stability and a pleasant motion.
The hull is fiberglass. Its capsize screening value of 1.71 means that, on this formula alone, the boat could be accepted for ocean racing.
Rig and Handling
The cutter rig has a short bowsprit and a mast stepped well aft. Its leading edge sits 43.2 percent of the waterline aft of the bow, deliberately leaving enough room in the foretriangle for a usable staysail.
The main chainplate is mounted outside the hull, while the forward and aft lowers are inboard. This arrangement simplifies the shroud angles, though the rig geometry can sometimes make the boat difficult to balance.
With 846 square feet of sail and a sail-area-to-displacement ratio of 16.26, the 40 is no lightweight sprinter. As the designer put it, the primary aim was ease of control by a small crew in bad conditions. The underbody was shaped to make passages relaxing, and sister boats in the range have reportedly surfed down waves in heavy weather at speed/length ratios above 2 while remaining easy to control.
Accommodations
The interior makes room for substantial cruising tankage: 70 gallons of diesel and 150 gallons of water. The galley is large, with its sinks near the centerline, and the head is big enough for a separate shower stall.
The reefer box extends into the aft cabin, where it forms a small shelf. Because the mast is stepped so far aft, there’s access to both ends of the dinette.
Forward, buyers could choose either an island double berth or a conventional V-berth with a filler. That degree of flexibility is unusual in a boat of this weight and beam.
Known Issues
The only handling caveat is the rig geometry. Moving the mast aft creates room for the staysail, but it can also leave the boat difficult to balance at times. The reviewing tester noted this as a characteristic rather than a fault requiring correction.
Beyond that, any used Pacific Seacraft 40 should be assessed on its own maintenance history rather than against a known weakness of the class.
The Verdict
The Pacific Seacraft 40 is a purposeful offshore cutter that trades outright light-air speed for stiffness, stability, and manageability by a small crew in heavy weather. Crealock’s rounded sections and large skeg contribute to a pleasant motion, while the split underbody has proved capable of controlled surfing in heavier seas. The accommodations are generous for a 40-foot hull, with an unusually adaptable forward cabin.
Pros
- Heavy, stiff construction, high positive stability, and a 1.71 capsize screening value
- Cutter rig with a dedicated staysail and an outside main chainplate for clean leads
- Flexible forward-berth layouts and a large galley with centerline sinks
- Capacity for 150 gallons of water and 70 gallons of fuel
Cons
- The aft mast position can make the boat difficult to balance
- The low SA/D ratio limits light-air performance
- Heavy displacement and 16-degree deadrise favor passagemaking over daysailing
