Design Brief & Intent
Stan Huntingford designed the Explorer 45 with a clear mandate: to create an honest, uncompromised offshore voyaging platform that prioritizes crew safety and comfort over racing silverware. During an era when many production boats were beginning to embrace lighter, flatter hull forms, the Explorer 45 doubled down on traditional heavy displacement, a deep full keel with a cutaway forefoot, and a heavily protected skeg-hung rudder.
The model is often compared directly to its contemporary, the iconic Kelly Peterson 44. While sharing a similar aft-cabin, center-cockpit layout, the Explorer 45 distinguished itself by offering significantly more interior headroom, larger and brighter portlights, and an even more heavily built solid-GRP laminate hull.
The interior of the Explorer 45 reflects the peak of Taiwanese craftsmanship from the late 1970s. The joinery is dominated by solid teak and mahogany, boasting hand-rubbed varnished finishes, an arched spruce overhead, and a traditional teak-and-holly sole. The layout is optimized for long-range self-sufficiency, featuring a massive, secure U-shaped galley, a proper navigation station, and a low passageway leading to a cavernous master stateroom aft with an ensuite head.
Variations & Configurations
While the basic hull shape remained uniform, C&L Marine delivered the Explorer 45 in a few distinct rig and deck configurations. The vast majority of the hulls were built with a deep center cockpit. However, a small handful of aft-cockpit versions were produced to satisfy traditionalists who preferred a single-level deck line and a more conventional steering position.
In terms of sail plans, the two primary configurations were the staysail ketch and the cutter rig.
- The Staysail Ketch: This split-rig configuration features a mainmast with a self-tacking, boomed staysail paired with a smaller mizzen mast stepped aft. The ketch rig is highly favored by short-handed couples because it breaks the total sail area into smaller, more manageable pieces, allowing for easy balancing and sail-reduction choices in heavy weather.
- The Cutter Rig: Standard on a portion of the production run, the cutter layout simplifies the rigging by eliminating the mizzen mast while retaining the inner forestay for a staysail. This configuration yields slightly better upwind performance and cleaner sightlines from the cockpit, though it demands more physical effort when managing the larger mainsail.
Sailing Performance & Handling
The physical performance of the Explorer 45 is a direct reflection of its traditional, heavy-displacement design. Weighing in at a nominal 30,000 pounds, the boat possesses a high displacement-to-length ratio of 340.75, placing it firmly in the heavy cruiser category. This massive displacement ensures that the boat can carry tons of cruising gear, water, and fuel without sacrificing its designed waterline or performance.
With a sail area-to-displacement ratio of 15.24, the Explorer 45 is moderately underpowered in light breezes (under 10 knots), where its wetted surface area creates noticeable drag 2. However, once the wind pipes up to 15 to 20 knots, the hull comes alive. Its ballast-to-displacement ratio of 34.77 percent, coupled with an encapsulated full keel, provides excellent stiffness under sail and a highly stable, upright posture.
In terms of motion, the boat is an absolute joy in a seaway. A comfort ratio of 40.75 translates to a slow, motion-dampened roll and a gentle entry into head seas, which drastically reduces crew fatigue 2. Additionally, a capsize screening ratio of 1.67 indicates exceptional ultimate stability and resistance to roll-overs, well exceeding the industry threshold for ocean-crossing safety.
The full-keel design with a cutaway forefoot allows the boat to track straight for hours, meaning the autopilot or windvane steering has to do very little work. The trade-off is a large turning radius and a notoriously unpredictable stern-walk when backing down under power in tight marinas, requiring a skilled hand on the helm during docking maneuvers.
Market Snapshot & Economics
Because of their low production numbers and legendary build quality, Explorer 45s occupy a niche "budget-bluewater" status on the brokerage market. They generally trade at a relative value compared to more widely known brands like Valiant or Hylas, making them an attractive gateway for cruisers seeking a genuine ocean-crossing hull without paying a premium for a brand name.
However, any buyer entering this market must account for the reality of "Taiwanese vintage" refit economics. While a well-maintained or already refitted Explorer 45 represents a tremendous value, a neglected example can quickly become a financial sinkhole. The labor and material costs required to update the extensive woodwork, complex rigging, and vintage machinery of a 45-foot classic can easily exceed the initial purchase price of the vessel.
Known Issues & Triage
Prospective buyers must inspect an Explorer 45 with a keen eye for the common failure points of late-1970s Taiwanese builds:
- Teak Decks: Many hulls were delivered with teak decks screwed directly into a plywood-cored GRP deck. Over decades, the thousands of screw holes and failing caulking joints allow water to seep into the core, leading to extensive delamination and rot. Triage requires either a complete re-coring and fiberglassing over of the decks or a highly labor-intensive re-fastening of the teak.
- Fuel and Water Tanks: The original mild steel or black iron fuel tanks are a notorious failure point, corroding from the top down where water sits on them. Because these massive tanks were glassed in deep under the cabin sole before the deck was joined, replacing them requires destroying and rebuilding portions of the exquisite teak saloon joinery.
- Osmotic Blistering: While the solid-GRP hull is exceptionally thick and structurally robust, the early polyester resins utilized by C&L Marine are highly prone to osmotic blistering. A hull survey must assess whether the blisters are superficial or require a full bottom peel and barrier coat.
- Underpowered Propulsion: The factory-standard 35-horsepower Perkins engine is relatively small for a boat of this displacement. While adequate for flat-water harbor maneuvering, it lacks the grunt to push the heavy hull against a stiff headwind and chop, leading many owners to consider repowering a priority.
Modernization & Upgrades
Most active Explorer 45s have undergone, or are currently undergoing, significant modernizations to align them with contemporary cruising standards. Veterans of the model frequently focus on the following high-impact upgrades:
- De-Teaking: Many owners choose to strip the old, leaking teak decks entirely, filling the screw holes, re-coring any soft spots, and applying a modern, low-maintenance grip paint over a smooth fiberglass skin.
- Power & Propulsion: Repowering with a modern 50 to 80 horsepower diesel engine (such as a Yanmar or Beta Marine) is a common upgrade. This not only provides the necessary thrust for heavy weather but also brings vastly superior fuel efficiency and reliability.
- Electrical and Energy Self-Sufficiency: Given the boat’s excellent carrying capacity, owners routinely install robust stainless steel stern arches to support massive solar arrays (often exceeding 700 watts). This solar power is typically paired with a transition from traditional lead-acid batteries to high-capacity lithium iron phosphate (LiFePO4) banks, allowing cruisers to run large 12-volt refrigeration systems, watermakers, and satellite communication systems indefinitely without running the engine.
The Verdict 2
The Huntingford-designed Explorer 45 is a classic, go-anywhere cruiser built like a tank and finished like a fine home. It is not a boat for those who want to zip between coastal marinas in light air, but for the offshore sailor who values a comfortable, sea-kindly motion, massive storage, and an incredibly strong hull, it is one of the finest values on the classic market. As long as a buyer is prepared to address or avoid the common pitfalls of vintage Taiwanese construction, the Explorer 45 will look after its crew in conditions that would send modern, lightweight production boats running for shelter.
