The Pacific Seacraft Orion 27 stands as a cornerstone of the "pocket cruiser" philosophy, designed by company cofounder Henry Mohrschladt in 1979. While the builder eventually became synonymous with the designs of W.I.B. Crealock, the Orion 27 reflects Mohrschladt’s personal vision for a rugged, heavydisplacement cutter that punches well above its weight class in offshore conditions. Launched during the company’s formative years in California, the model remained in production through 1993, solidifying a reputation for "overbuilt" construction that enables a 27foot boat to tackle transoceanic passages with the confidence of a much larger vessel.

Sailing Performance & Handling

The Orion 27 is a unapologetically heavy-displacement vessel, displacing approximately 10,000 pounds on a 22-foot waterline. This gives it a Displacement-to-Length (D/L) ratio of over 400, a figure that signals exceptional stability and a "big boat" feel in a seaway. According to technical analysis in Sailing Magazine, the hull features a traditional wine-glass section and a long keel with a cutaway forefoot. This specific keel geometry is designed to balance the steady tracking required for long-distance cruising with a degree of nimbleness that full-keel boats often lack when maneuvering in tight harbors.

Under sail, the Orion is most commonly found with a cutter rig, though sloop and rare yawl configurations were also produced. The cutter rig, featuring a total sail area of approximately 508 square feet, provides versatile reefing options for heavy weather. While it is not a light-air performer—often requiring the engine to maintain speed in under 10 knots of breeze—it excels when the wind picks up. Owners frequently report that the boat remains well-balanced and "heaves-to" predictably, a critical safety characteristic for solo or shorthanded sailors caught in a blow.

Interior Comfort & Variations

For a vessel of its length, the Orion 27 offers an unusually cavernous interior, aided by a 9'3" beam and a cabin house that provides 6'1" to 6'2" of headroom. The interior is finished with the high-grade teak joinery and bronze portlights that defined Pacific Seacraft’s "golden era." The model underwent a significant evolution in 1981 with the introduction of the Orion 27 Mk II. This variant featured a lengthened coachroof that allowed for an extra set of portlights forward, significantly increasing natural light and ventilation in the bow.

Two primary interior arrangements were offered:

  • Plan A (Standard): This layout was designed for coastal cruising and social flexibility, featuring a large U-shaped dinette to port that converts into a double berth, with a galley located to starboard.
  • Plan C (Offshore): Targeted at long-distance voyagers, this layout replaced the large dinette with a smaller table to make room for a dedicated wet locker at the foot of the companionway. It also emphasized a larger V-berth for improved comfort while at anchor in remote locations.

The Orion 27 earned its place in the blue-water hall of fame through the exploits of sailor Brechin Morgan. Between 1998 and 2003, Morgan successfully circumnavigated the globe aboard his cutter-rigged Orion 27, named Otter. This voyage served as a real-world proof of concept for the design’s durability, as Morgan crossed the Atlantic, Pacific, and Indian Oceans in a boat many critics at the time considered too small for such an undertaking.

Known Issues & Buyer’s Checklist

Prospective buyers should approach a used Orion 27 with a focus on the structural integrity of its aged components:

  • Deck Core Integrity: The decks are constructed with a balsa or plywood core (depending on the year). Areas around stanchion bases, the bowsprit, and the butterfly hatch should be thoroughly sounded with a phenolic hammer to check for delamination or moisture ingress.
  • Chainplate Inspection: The Orion features heavy-duty stainless steel chainplates. While robust, they are now decades old on most hulls; buyers should inspect the points where they pass through the deck for signs of crevice corrosion or "bleeding" rust.
  • Engine Access and Maintenance: One of the Orion's best features is a removable cockpit sole hatch that provides unparalleled access to the inboard diesel (typically a Yanmar or Universal). However, the seals on this hatch can fail over time, leading to saltwater dripping onto the engine; ensure the hatch gaskets have been maintained.
  • Portlight Gaskets: The heavy bronze portlights are a signature feature, but the safety glass can delaminate or the rubber gaskets can perish, leading to persistent leaks that damage the teak interior.

Community & Resources

The model is supported by a dedicated community of enthusiasts, primarily organized through the Pacific Seacraft Orion 27 Club. This group serves as a technical wiki for owners, sharing specific refit advice ranging from bowsprit replacement to engine repowering.

The Verdict

The Pacific Seacraft Orion 27 is a purpose-built tool for the sailor who values safety and construction quality over raw speed or dockside "condo" space.

Pros

  • Exceptional "blue-water" build quality with encapsulated lead ballast.
  • Impressive headroom and interior volume for a 27-foot hull.
  • The Mk II variant offers excellent ventilation and light.
  • Superb engine access through the removable cockpit sole.

Cons

  • Heavy displacement makes it sluggish in light winds.
  • Significant amount of exterior teak requires high maintenance.
  • Higher price point on the used market compared to lighter 27-foot production boats.
