The Garrett 40 Gpr MH is a performanceoriented cruiserracer that emerged from a notable collaboration between the prolific naval architect Bruce Farr and the Floridabased builder Garrett Marine Inc. in the early 1980s. Designed to balance the requirements of a competitive racing hull with the structural integrity needed for offshore cruising, the model is a departure from the heavydisplacement "doubleenders" often associated with similar names. Instead, the Garrett 40 Gpr MH features a contemporary finkeel and spaderudder configuration, housed within a glassreinforced plastic (GRP/GPR) hull. The "MH" designation specifically identifies the Masthead Rig variant, which was marketed alongside its sibling, the Garrett 40 GPR FR (Full Race fractional rig), and a more accommodationfocused cruising version.

Sailing Performance & Handling

The sailing characteristics of the Garrett 40 Gpr MH are defined by a remarkably high ballast-to-displacement ratio, often cited near 50%. With roughly 7,100 lbs of lead ballast against a total displacement of approximately 13,900 lbs, the vessel is exceptionally stiff, allowing it to stand up to its canvas in heavy air long after lighter boats have been forced to reef. This stability is paired with a moderate Displacement/Length (D/L) ratio of approximately 210, positioning it as a versatile performer that tracks well on passage while maintaining the responsiveness typical of a Bruce Farr design.

Under sail, the masthead rig provides a powerful plan for offshore work, though the deep draft—approaching 7.8 feet—dictates a commitment to deep-water navigation. Technical evaluations of the hull form suggest a theoretical maximum hull speed of roughly 7.5 knots, though owners often find the boat capable of exceeding this on a reach due to its relatively flat aft sections. The spade rudder provides sharp, immediate feedback at the helm, a trait inherited from Farr’s racing pedigree, making the boat feel more nimble than a standard 40-foot cruiser of its era.

Interior Comfort & Variations

While the Garrett 40 was born from a performance ethos, the interior was designed to support extended stays at sea. The layout typically follows a traditional 1980s offshore arrangement: a forward V-berth, a central salon with a drop-leaf table, and a dedicated navigation station situated opposite a sea-kindly U-shaped galley. Because the beam is quite generous at 13.25 feet, the salon feels expansive for a boat of this vintage, offering more lateral room than many of its European contemporaries.

The builder offered the hull in several distinct variations to suit different buyer profiles. While the GPR MH (Masthead) served as the standard high-performance cruiser, the GPR FR (Fractional Rig) was tailored for IMS/IOR racing circuits of the time. Additionally, a Keel/Centerboard version was produced for sailors in shallower regions like the Chesapeake or the Bahamas, though these are significantly rarer on the used market. Interior finishes were generally executed in teak with a focus on structural robustness over ornate joinery.

Known Issues & Buyer’s Checklist

  • Chainplate Integrity: As with many early 80s performance boats, the chainplates are high-load points. Potential buyers should inspect the bulkheads where chainplates are through-bolted for signs of water ingress or "weeping," which can lead to structural rot.
  • Spade Rudder Bearing: The spade rudder is a high-aspect-ratio design. Inspect the rudder post and bearings for excessive play or "slop," which can indicate worn bushings or past impact damage.
  • Deck Core Saturation: The decks are typically balsa-cored. Use a moisture meter or perform a percussion (tap) test around high-stress areas like the mast step and genoa tracks to ensure the core remains dry and delamination-free.
  • Draft Limitations: The standard 7.8-foot draft is a significant operational constraint. Buyers should verify their intended cruising grounds or slip availability, as this depth prevents access to many common coastal anchorages.

The Verdict

The Garrett 40 Gpr MH is a "sleeper" in the brokerage market—a high-quality Bruce Farr design that offers offshore stability and racing-level responsiveness for a fraction of the cost of a modern performance cruiser.

Pros

  • Exceptional Stiffness: The 50% ballast ratio makes it one of the most stable boats in its size class.
  • Proven Pedigree: Designed by Bruce Farr, ensuring excellent upwind performance and helm balance.
  • Versatile Hull: Capable of both club racing and serious offshore passage-making.

Cons

  • Deep Draft: The nearly 8-foot draft significantly limits coastal cruising and gunkholing options.
  • Aging Systems: As a product of the early 80s, many units require updates to standing rigging and original electronics.
  • Limited Production: Finding specific replacement parts from the defunct Garrett Marine Inc. can be challenging, requiring custom fabrication.
