Design Brief & Interior Layout
The core mission of the Seafarer 36 C was to provide a safe, comfortable, and highly liveable home on the water for couples and small families. Philip Rhodes designed a hull with a traditional spooned bow, an elegant counter transom, and a modified long keel with a cutaway forefoot. This configuration minimized draft to a modest four and a half feet, a deliberate design choice that allowed owners to navigate the shoal waters of the Bahamas, Chesapeake Bay, and the Florida Keys without sacrificing offshore tracking.
Stepping below decks, the interior spaces are defined by a high volume of hand-laid joinery, rich teak and mahogany trim, and an open, airy arrangement that feels larger than its thirty-six-foot length. The main saloon features a generous layout with ample headroom, a dedicated navigation station, and a functional galley situated near the companionway for optimal ventilation. The forward stateroom provides a V-berth with private access to the head, highlighting the boat's dual role as a coastal cruiser and a liveaboard platform. However, prospective buyers must note that Seafarer sold a significant number of these boats as "kits" or semi-finished shells. Consequently, the quality of the interior joinery, plumbing, and electrical distribution can vary dramatically from meticulous factory-finished models to more utilitarian, amateur-completed examples.
Rig and Hull Configurations
Seafarer offered the 36 C in two distinct rigging configurations, each altering the boat's utility and sailing characteristics. The standard and most common configuration was the Masthead Ketch. By splitting the sail plan between a main and a mizzen mast, Rhodes created an easily managed rig for shorthanded cruising couples. Under a ketch rig, owners can comfortably sail under "jib and jigger" (headsail and mizzen) in heavy weather, keeping the boat balanced and stable while the mainsail is safely doused.
For sailors prioritizing windward performance and simplicity, Seafarer offered an optional Masthead Sloop configuration. This version eliminated the mizzen mast entirely and utilized a taller, high-aspect main mast. While the sloop configuration improved pointing angles and reduced aerodynamic drag, it required a stronger physical effort to manage the larger mainsail and headsails. Underneath both rigs, the underbody remained identical: a solid, hand-laid fiberglass hull with an encapsulated lead ballast of 5,500 pounds, ensuring that regardless of the rig, the boat maintained an exceptionally low center of gravity and excellent righting ability.
Sailing Performance & Handling
With a displacement of 16,350 pounds and a water line length of just over twenty-six feet, the Seafarer 36 C is a textbook heavy-displacement cruiser. This physical reality is borne out by its performance metrics. The boat’s displacement-to-length ratio of 403.54 highlights its substantial weight, which pays massive dividends in rough water. When waves build and the sea becomes confused, the 36 C exhibits an incredibly stable and comfortable motion. Its high comfort ratio of 37.67 translates to a slow, easily tolerated roll and a dry ride, preventing the rapid, fatiguing accelerations common in lighter, modern fin-keel designs. This offshore security is further bolstered by a capsize screening ratio of 1.66, which sits comfortably below the safety threshold of 2.0, proving the boat’s inherent self-righting capacity.
The trade-off for this heavy-weather comfort is found in light-air performance. Sporting a modest sail area-to-displacement ratio of 12.57, the 36 C is heavily under-rigged by modern standards. In light breezes under ten knots, the vessel can feel sluggish and will require the assistance of its auxiliary engine to maintain reasonable headway. At the helm, the modified long keel and keel-mounted rudder provide excellent directional tracking, allowing the boat to hold its course with minimal helm correction—a characteristic highly prized by single-handed sailors and those using windvane self-steering. However, this same directional stability makes maneuvering in tight marinas challenging, as the boat has a large turning radius and responds slowly to the rudder when operating in reverse.
Known Issues & Triage
Decades after leaving the Huntington shipyard, several model-specific vulnerabilities have emerged that require careful evaluation by prospective owners. The most critical structural concern involves the original chainplates. Seafarer chose to fiberglass the stainless steel chainplates directly into the hull sides. Over time, water inevitably leaks past the deck chainplate covers and runs down the metal. Because the chainplates are fully laminated inside the fiberglass hull, this moisture becomes trapped, creating a classic environment for hidden crevice corrosion. Owners and surveyors cannot easily inspect these chainplates without grinding away the internal fiberglass lining. Triage requires grinding back the structural GRP, extracting the compromised plates, and fabricating new chainplates. Many owners choose to relocate the chainplates to the exterior of the hull or engineer robust interior backing brackets that are bolted through the hull rather than glassed in.
Another area requiring attention is deck core integrity. While the hull is solid fiberglass, the decks were constructed with a balsa or plywood core. Decades of neglected rebedding of stanchions, handrails, cleats, and the windlass lead to water intrusion, rot, and delamination. Soft spots are common on the side decks and cabin top, demanding local recoring with epoxy and high-density foam or new plywood. Additionally, the original mild steel fuel tanks are known to corrode from the outside in due to condensation and wet bilge conditions, frequently requiring tank replacement, which can be labor-intensive depending on access.
Modernization & Upgrades
The original auxiliary power was often a heavy, 70-horsepower Universal-Atomic engine, which cemented the boat's motorsailer credentials and gave it the muscle to drive through heavy head seas. Today, many veteran owners are opting for modern diesel repowers. Replacing the original heavy cast-iron engine with a lighter, highly efficient 25 to 40 horsepower diesel (such as a Beta Marine or Yanmar) provides several advantages. While the horsepower rating is lower, modern prop design and marine transmissions allow these engines to easily achieve hull speed while saving hundreds of pounds of displacement, drastically improving fuel economy, and freeing up immense space in the engine compartment.
Electrical systems are also prime candidates for modernization. The original wiring, often complicated by amateur "kit" completions, rarely meets modern safety standards. A standard upgrade path includes stripping the old wiring, installing a modern breaker panel, and integrating high-capacity lithium iron phosphate (LiFePO4) house battery banks. Given the boat's heavy displacement and stable motion, it is an excellent candidate for solar array installations on a custom stern arch, providing the energy independence required for extended off-grid cruising.
The Verdict
The Seafarer 36 C is a heavily built, traditional offshore cruiser that trades modern speed and agility for ultimate comfort and structural peace of mind. For the budget-conscious sailor looking to embark on bluewater passages or live aboard, it offers incredible value, provided the owner is willing to address age-related structural triage. It remains a handsome, capable testament to the genius of Philip Rhodes, built to outlast its contemporaries.
