Spencer 35 Mk II Information, Review, Specs

Sailing Performance & Handling

The Spencer 35 Mk II is characterized by its high displacement-to-length ratio (approximately 343) and a narrow 9'6" beam, a combination that favors sea-kindliness over light-air agility. It features a full keel with a cutaway forefoot and a skeg-hung rudder, a configuration that provides excellent directional stability when tracking through a seaway. According to technical evaluations found via Pacific Yachting, the boat is notably responsive for a heavy-displacement cruiser, though its slack bilges mean it is relatively tender initially, typically finding its "groove" at about 25 to 30 degrees of heel.

The Mk II received a higher aspect masthead rig compared to the original design, which improved its performance in moderate breezes. With a motion comfort ratio of nearly 33, the hull is designed to slice through a chop rather than pound over it, making it an ideal platform for the challenging "wind-against-tide" conditions common in the Inside Passage. While it is not a competitive "around the buoys" racer, its capability is evidenced by the Spencer 35 Haulback, which took first place overall in the 2002 Singlehanded Transpac, proving that the design remains a formidable long-distance performer under the right hand.

Interior Comfort & Variations

One of the most significant departures in the Mk II was the redesign of the cabin house and interior layout, largely influenced by the offshore experiences of legendary cruiser Hal Roth. The cabin trunk was extended approximately 30 inches aft, a change that sacrificed some cockpit space to gain substantial volume in the main saloon. This modification allowed for a much more functional galley—noted by designer Ted Brewer as one of the best layouts for a vessel of this size—and the addition of a proper quarterberth and a forward-facing navigation station.

The interior finish is typically heavy in teak joinery, reflecting the semi-custom nature of Spencer Boats. Headroom is generous at 6'4" in the main cabin, which is exceptional for a 35-footer of this era. Because many hulls were sold in varying stages of completion, including kit versions, interior fit-outs can range from professional shipyard cabinetry to more utilitarian owner-built configurations. Sibling models built on related Brandlmayr hulls include the Spencer 31, which offers similar lines in a smaller footprint, and the Spencer 42 and 44, which provided center-cockpit options for larger crews.

Popular Mentions & Media

The Spencer 35’s global reputation was largely built through the writing of Hal Roth, who chronicled his world travels with his wife Margaret aboard their Spencer 35, Whisper. Roth's books, such as Two on a Big Ocean, became foundational texts for the cruising community and are frequently cited by Cruising World as a primary reason for the model's enduring fame. The boat’s cultural footprint is further supported by its frequent appearances in regional literature and documentaries focusing on Pacific Northwest "classic plastic" yachts.

Known Issues & Buyer’s Checklist

Prospective buyers should focus on several technical areas specific to the Spencer 35 Mk II’s construction and age:

• Deck and Hull Core: While the Mk II used Airex foam coring in the hull to improve stiffness and insulation, the decks were typically cored with end-grain balsa. Check for soft spots around high-load areas like the mast step and stanchion bases, where water intrusion can lead to delamination.
• Chainplate Leaks: Like many boats of this vintage, the stainless steel chainplates can leak where they pass through the deck, potentially leading to bulkhead rot if not regularly re-bedded.
• Encapsulated Ballast: The lead ballast is encapsulated within the fiberglass keel. Inspect the "smile" at the leading edge of the keel for any signs of impact damage or structural cracking.
• Original Engines: Many units were originally fitted with Bukh or early Volvo Penta diesels. Due to the tight engine space, confirm that regular maintenance has been performed or budget for a modern repower.
• Osmotic Blistering: While Spencer hulls were generally well-laid, earlier fiberglass resins are prone to osmotic blistering; a haul-out survey is essential to check the hull's integrity below the waterline.

Community & Resources

The most prominent hub for technical support is the Spencer Yacht Owners Group (SYOG), an active community that maintains archives of original drawings and modification logs. Owners also frequently congregate within the Bluewater Cruising Association, particularly in Western Canada, where the Spencer 35 Mk II is regarded as a legacy vessel.

The Verdict

The Spencer 35 Mk II is a purpose-built offshore machine that sacrifices interior width and light-air speed for safety, durability, and a comfortable motion in open water.

Pros:

• Exceptional sea-kindliness and motion comfort in heavy weather.
• Proven blue-water pedigree with numerous successful circumnavigations.
• Robust construction and high-quality semi-custom interior joinery.
• Excellent headroom and storage for long-term provisioning.

Cons:

• Narrow beam results in a smaller interior volume compared to modern 35-footers.
• Relatively tender initial stability can feel lively for novice sailors.
• Limited light-air performance requires a large genoa or cruising spinnaker.
• Balsa-cored decks require vigilant maintenance to prevent water ingress.
