Bruce Roberts Roberts 36 Information, Review, Specs

Sailing Performance & Handling

The Roberts 36 is designed primarily as a heavy-displacement cruiser, prioritizing stability and tracking over raw speed. Most versions feature a long fin keel and a skeg-hung rudder, a configuration that offers excellent directional stability and protection for the propeller and steering gear. When sailing off the wind, the hull's generous beam and displacement provide a predictable, "train-on-tracks" feel that reduces helm fatigue during long passages. However, its performance in light air is often criticized; with a high displacement-to-length ratio, the boat requires a stiff breeze to overcome its own inertia.

Handling characteristics are heavily influenced by the specific rig chosen by the builder. The design was offered with ketch, cutter, or sloop sail plans. The cutter rig is widely considered the most versatile for this hull, allowing for a flexible sail area that can be easily reefed in heavy weather. While the boat is not known for its pointing ability—rarely tacking tighter than 90 to 100 degrees—it excels in "heavy weather" scenarios where its weight allows it to punch through head seas that would stop lighter performance cruisers. Editorial reviews in vintage copies of Cruising World often noted that the Roberts 36 feels like a much larger vessel in open water, providing a sense of security that is rare in the 35-to-40-foot bracket.

Interior Comfort & Variations

Because the Roberts 36 was sold as plans, the interior layouts are as diverse as the builders who created them. Most designs follow a traditional offshore arrangement: a V-berth forward, a central salon with a drop-leaf table, and a galley located near the companionway for optimal ventilation and proximity to the cockpit. The "A" and "B" layout variations offered by Roberts allowed for either a large aft cockpit or a center-cockpit configuration. The center-cockpit version is particularly notable for providing a dedicated aft cabin, though this can sometimes result in a "high-profile" deckhouse that increases windage.

Headroom is generally excellent, often exceeding 6'3" in the main salon, as the design accounts for the structural depth required by steel or thick fiberglass hulls. Material quality varies significantly; some interiors feature professional-grade teak joinery, while others utilize painted marine plywood. Prospective buyers should note that the Roberts 36 was often built alongside its slightly larger sibling, the Roberts 38, and many 36-foot hulls were "stretched" during the building process to include a swimming platform or additional storage, resulting in custom lengths that do not always align with the original blueprints.

Popular Mentions & Media

The Bruce Roberts 36 and its variants are staples of the shoestring-budget cruising community. While it lacks the "prestige" of a Hinckley or a Hallberg-Rassy, its cultural footprint is cemented in the thousands of blogs and early sailing forums where builders documented their multi-year construction projects. The design is frequently cited in "How to Build Your Own Boat" literature by Bruce Roberts-Goodson himself, which served as a primary resource for the DIY boat-building boom of the 1970s and 80s.

Known Issues & Buyer’s Checklist

The primary challenge with a Roberts 36 is "build consistency." Because these are not factory boats, the quality of the original weld (on steel models) or the layup (on fiberglass models) must be the first priority for any inspector.

• Steel Corrosion: On steel-hulled Roberts 36s, corrosion from the inside out is the most common failure point. Check the "hidden" areas like the bilge under the engine, the chain locker, and behind the cabinetry where condensation collects.
• Deck Core Integrity: For fiberglass versions, many were built using foam or balsa cores. Improperly bedded deck hardware can lead to water intrusion and delamination. A thorough "perc" test with a fiberglass hammer is essential.
• Lead Ballast Encapsulation: In some owner-built versions, the ballast was not properly sealed, leading to "expansion" issues if water enters the keel, which can crack the fiberglass or cause rust-jacking in steel keels.
• Weight Deviations: Amateur builders often added excessive weight in the form of heavy cabinetry or oversized tanks. This can lead to the boat sitting significantly below its designed waterline, affecting stability and performance.

Community & Resources

The community surrounding Bruce Roberts designs is one of the most robust in the world. The official Bruce Roberts-Goodson website remains a primary repository for technical drawings and support. Additionally, the Bruce Roberts Owners Group (often found on social platforms and independent forums) provides a deep archive of "as-built" modifications and advice for maintaining these aging cruisers.

The Verdict

The Bruce Roberts 36 is a rugged, capable blue-water cruiser for those who value structural integrity and DIY-repairability over modern aesthetics or racing performance. It is a "true sailor's boat" that requires a discerning eye during the purchase process to separate the masterfully built examples from the amateur attempts.

Pros:

• Extreme durability, particularly in steel-hulled variants.
• Exceptional directional stability and sea-kindly motion in heavy weather.
• Highly affordable entry point into serious offshore cruising.
• Strong designer support and a vast community of fellow owners.

Cons:

• Wide variance in build quality and interior finish.
• Sluggish performance in light winds and poor upwind pointing.
• Potentially high maintenance requirements for steel hulls (rust management).
• Difficult to resell compared to standardized production models.
