Aura A35 Information, Review, Specs

The vessel shares its hull form with several notable contemporaries, as Sparkman & Stephens licensed the design to multiple builders. The most direct siblings include the Hughes 35, built by Hughes Boat Works in Canada, and the North Star 1500, produced by North Star Yachts. A highly refined version of the same lines was also used for the SHE 36, built by South Hants Engineering in the UK, which is widely regarded as one of the finest-handling yachts of its size from that era.

Sailing Performance & Handling

Under sail, the Aura A35 exhibits the classic "S&S" characteristics: exceptional tracking, a soft motion in a seaway, and a high degree of stiffness. With a displacement of 12,000 lbs and a ballast-to-displacement ratio of 45%, the boat is notably stable. According to technical assessments on Wikipedia, its high ballast ratio enables the boat to resist heeling effectively, allowing it to carry full sail longer than many modern light-displacement alternatives.

The boat features a fin keel and a skeg-mounted rudder, a configuration that provides a superior "on rails" feeling when sailing upwind. While its Displacement/Length (D/L) ratio of 305 classifies it as a "heavy cruiser" by modern standards, the hull's relatively narrow beam of 11 feet and deep 5.83-foot draft contribute to its ability to slice through a chop without the slamming common in flatter-bottomed designs. However, the masthead sloop rig is somewhat modest in sail area (503 sq. ft.), leading some reviewers to categorize it as slightly under-rigged for light-air performance. In breezes above 12 knots, the boat finds its stride, consistently hitting its theoretical hull speed of 6.8 knots with ease and predictability.

Interior Comfort & Variations

The interior of the Aura A35 reflects the cruising standards of the mid-1970s, offering a functional and seaworthy layout designed for a crew of six. The accommodations typically feature a traditional V-berth forward, followed by a head and hanging locker. The main salon is composed of two straight settees that serve as sea berths, flanking a central drop-leaf table.

Consistent with the "offshore" philosophy of Sparkman & Stephens, the galley is positioned near the companionway for optimal ventilation and accessibility while underway. The use of warm teak joinery and a manageable 6-foot-plus headroom creates a traditional, cozy atmosphere. Because the A35 was built on the same hull as the North Star 1500 and Hughes 35, interior finishes can vary significantly between specific hulls, with some owners opting for more extensive woodwork while others prioritized the weight savings of a simpler fiberglass liner.

Known Issues & Buyer’s Checklist

Prospective owners of an Aura A35 should focus on the following common technical areas, many of which are typical for vessels of this vintage:

• Deck Core Integrity: Like many 1970s builds, the A35 utilized balsa-cored decks. High-moisture readings or "soft spots" are common around hardware fittings (cleats, stanchions, and the mast step) where original bedding may have failed.
• Keel-Hull Joint: Inspect the "Catalina smile" or hairline cracks at the leading edge of the keel-to-hull joint. While the A35 features a robust internal grid, decades of stress can lead to minor separation that requires re-torquing of the keel bolts and fairing.
• Skeg and Rudder Bushings: The skeg-mounted rudder provides excellent protection but is prone to wear in the lower bronze gudgeon or the upper bushings. Significant "slop" in the tiller or wheel indicates a need for replacement.
• Chainplate Anchors: Check the bulkheads where the chainplates are through-bolted. Water intrusion from deck-level leaks can rot the plywood bulkheads, compromising the rig's structural integrity.
• Engine Obsolescence: Many original A35s were fitted with the Universal Atomic 4 gasoline engine. While reliable if maintained, many have been repowered with diesels; buyers should verify the age and condition of the cooling system and sail-drive seals if applicable.

Community & Resources

Owners of the Aura A35 and its variants are supported by a dedicated community of Sparkman & Stephens enthusiasts. Technical documentation and design history can often be sourced through the Sparkman & Stephens Association, which maintains an archive of design specifications and performance data for hulls produced under the S&S 2166 design series.

The Verdict

The Aura A35 is a "sailor’s boat" that prioritizes structural integrity and seaworthy handling over the voluminous interior accommodations of modern coastal cruisers. It is an ideal choice for the budget-conscious offshore sailor or the classic yacht enthusiast who values the pedigree of a world-class design firm.

Pros

• Exceptional stability and upwind tracking thanks to its S&S pedigree.
• Heavy-duty fiberglass construction and a high ballast ratio.
• A "true" cruiser-racer that remains capable of serious offshore work.

Cons

• Requires a healthy breeze to overcome its high displacement.
• Interior volume is significantly less than modern 35-footers.
• Likely requires upgrades to older systems (engine, plumbing, wiring) due to age.
