The Northstar 1500, later rebranded as the Hughes 35, represents a high-water mark in the collaboration between Canadian builder Hughes Boat Works and the legendary design firm Sparkman & Stephens. Commissioned during the era of US Steel’s ownership (operating as Northstar Yachts), the vessel was penned under S&S Design No. 2166. It was conceived as a sophisticated performance cruiser capable of competing under the prevailing IOR (International Offshore Rule) while maintaining the structural integrity required for serious offshore passages. The model is part of a lineage that includes the Northstar 1000 (Hughes 31) and the Northstar 80/20 (Hughes 40), and it remains one of the most respected hulls to emerge from the Huron Park facility.

Sailing Performance & Handling

The Northstar 1500 is fundamentally a "sailor’s sailboat," defined by the classic Sparkman & Stephens balance between windward ability and sea-kindliness. Built with a moderate-to-heavy displacement and a fin keel paired with a skeg-hung rudder, the boat tracks with remarkable precision. Unlike the extreme IOR "pinched" sterns of its contemporaries, the 1500 retains enough volume aft to avoid the aggressive rolling often associated with racing boats of the 1970s.

On the water, the boat is known for its stiffness and ability to carry sail into the upper teens before requiring a reef. According to technical archives from Sparkman & Stephens, the hull was designed to be competitive yet forgiving. This versatility is further evidenced by its British cousin, the S.H.E. 36, which utilized the same hull mold and was famously praised in Yachting Monthly for its exceptional balance and "delightful" helm response. Owners report that the Northstar 1500 excels in a chop, where its weight and sharp entry allow it to punch through waves without the jarring motion typical of modern, flat-bottomed production boats.

Interior Comfort & Variations

The interior of the Northstar 1500 is a study in traditional yacht design, characterized by a functional, sea-going layout that prioritizes safety over open-concept aesthetics. The typical configuration features a V-berth forward, followed by a head and hanging locker that provides a structural transition to the main salon. The salon usually employs a pilot berth and a pull-out settee, a common feature in Sparkman & Stephens designs of this era to maximize sleeping capacity during offshore races.

When the model transitioned from the Northstar 1500 to the Hughes 35 in the late 1970s, the interior underwent various refinements. The Northstar-era boats often featured more utilitarian finishes, while the later Hughes-branded versions occasionally showcased richer teak joinery. A notable variation exists in the boats sold as "kits." Because Hughes offered these vessels in various stages of completion, interior quality and layout can vary significantly between individual hulls on the secondary market. Some owners opted for a more open galley-aft arrangement, while others strictly followed the factory blueprints. The Aura H35, built after Hughes went into receivership in 1980, continued this lineage with minor cosmetic updates but retained the core S&S-designed interior volume.

Known Issues & Buyer’s Checklist

Prospective buyers should approach a Northstar 1500 or Hughes 35 with an eye toward the specific manufacturing practices of the 1970s Canadian marine industry.

  • Deck Delamination: Like many boats of this period, the decks are balsa-cored. Freshwater intrusion around stanchion bases and chainplates is a common culprit for core rot. A thorough percussion test (hammer sounding) or moisture meter check is essential.
  • Chainplate Knees: The load from the rig is transferred to the hull via fiberglass-encapsulated wood knees. Over decades, water can seep down the chainplates and rot these structural members, necessitating a complex repair.
  • Rudder Post and Skeg: While the skeg-hung rudder is a robust design, the bearings and the integrity of the skeg attachment point should be inspected for play or "smile" cracks at the hull-to-skeg join.
  • Engine Access: While the engine (originally often a Universal Atomic 4 or a small Westerbeke/Yanmar diesel) is centrally located for weight distribution, access for major repairs can be tight, requiring the removal of companionway steps and side panels.

Community & Resources

The primary hub for technical support is the Sparkman & Stephens Association, which maintains records for Design No. 2166. While a formal Hughes-specific factory support office no longer exists, the S&S archives provide the most authoritative source for original sail plans and rigging specifications.

The Verdict

The Northstar 1500 / Hughes 35 is a quintessential classic cruiser that offers pedigree performance at a fraction of the cost of more modern equivalents. It is an ideal vessel for the sailor who values "the feel of the helm" and offshore capability over interior volume and "condo-style" amenities.

Pros

  • Exceptional Sparkman & Stephens handling and upwind performance.
  • Robust construction suitable for coastal or blue-water passage making.
  • Classic, timeless aesthetic that maintains its value among enthusiasts.
  • Skeg-hung rudder provides a superior safety margin compared to spade rudders.

Cons

  • Interior can feel cramped compared to modern 35-footers with wider beams.
  • Potential for significant core issues if deck hardware has not been re-bedded.
  • Variability in finish quality among kit-built versions.
