Northshore 27 — Information, Review, Specs

Sailing Performance & Handling

The Northshore 27 is frequently praised for its "big boat" feel, a characteristic derived from its high ballast ratio of approximately 44%. With a displacement of roughly 2,500kg and over 1,100kg of lead in its fin keel, the boat is remarkably stiff and stands up well to its sail plan in a breeze. This design philosophy makes it particularly well-suited for regions known for "choppy" conditions and sudden gusts, as the hull maintains momentum and tracks well upwind.

Handling is governed by a well-balanced spade rudder that provides responsive steering without the heaviness associated with many 27-footers of its generation. According to performance data and historical class reviews from the Northshore Yachts Association, the boat is most efficient when kept relatively flat; while its IOR-influenced hull shape (evident in the slight tumblehome and pinched ends) suggests a tendency to heel, the lead ballast provides a firm secondary righting moment. Under power, the Northshore 27 was originally equipped with small diesels, typically the Bukh 10 or Yanmar 1GM10, which provide sufficient thrust for harbor maneuvers but may struggle against a strong headwind and tide.

Interior Comfort & Variations

For a 27-foot yacht designed in the late 1970s, the Northshore 27 offers a surprisingly ergonomic interior that maximizes its 2.8-meter beam. The standard layout features a traditional V-berth forward, followed by a compact enclosed head to port and a hanging locker to starboard. The main saloon utilizes a twin-settee arrangement with a central folding table, providing enough seating for four adults.

A key highlight of the interior is the 1.8-meter (approx. 5'11") headroom, which is generous for a vessel of this length and prevents the "closed-in" feeling common in contemporary designs. The galley is typically located to starboard of the companionway, featuring a two-burner stove and a deep sink, while a sizable quarter berth to port serves as an excellent sea berth or additional storage.

While the hull remained consistent throughout its production run, interior finishes evolved. Early models featured more heavy timber and darker teaks, while later versions (often referred to as the "Series II" or modified variants) moved toward lighter finishes and improved molding liners. The sibling Northshore 31 and Northshore 33 models expanded on this layout, but the 27 remains the most sought-after for those prioritizing ease of maintenance and single-handed slip fees.

Popular Mentions & Media

The Northshore 27 has maintained a robust cultural footprint within the Australian sailing community, particularly in Sydney and Perth. It has been a staple of the Middle Harbour Yacht Club and similar organizations for decades, often participating in dedicated "Northshore" regattas. The model is frequently cited in regional sailing journals, such as Cruising Helmsman, as the gold standard for an entry-level keelboat.

Known Issues & Buyer’s Checklist

Prospective buyers of a Northshore 27 should focus their inspection on several age-related technical areas common to GRP boats of this vintage:

1. Mast Step and Compression: Check for any "cradling" or depression in the cabin top around the mast step. Over time, the internal support post or the deck core beneath the mast can compress, leading to rigging tension issues.
2. Rudder Delamination: The spade rudder is a composite structure. Moisture ingress can lead to internal corrosion of the stainless steel tangs or delamination of the fiberglass skins. A "tap test" or moisture meter reading is essential.
3. Chainplate Leakage: Like many production boats, the chainplates are bolted through the deck. If the sealant has failed, water can migrate into the plywood bulkheads, causing rot that compromises structural integrity.
4. Engine Longevity: Many 27s still carry their original Bukh or Yanmar engines. While these are "bulletproof" units, parts availability for older Bukh models is becoming more difficult, and buyers should check the exhaust elbow and raw-water cooling passages for scale buildup.
5. Window Leaks: The large side portlights are known to develop leaks over decades, which can damage the interior timberwork if left unaddressed.

Community & Resources

The Northshore 27 benefits from an active and knowledgeable community. The Northshore Yachts Association serves as a central hub for owners, providing technical documentation, historical brochures, and a forum for discussing maintenance and racing tips. Because so many were built, technical advice on specific modifications—such as adding a stern swim ladder or upgrading the traveler system—is readily available through these owner networks.

The Verdict

The Northshore 27 remains a premier choice for sailors seeking a robust, sea-kindly vessel that refuses to feel "small" on the water. Its combination of Kaufman's performance-oriented lines and a functional, upright interior makes it a standout in the 25–30ft category.

Pros:

• Exceptional ballast-to-displacement ratio provides a safe, stable ride.
• Genuine standing headroom rarely found in boats of this length.
• Strong resale value and an active class association.

Cons:

• Original engines are nearing the end of their service life.
• Interior can feel cramped if more than three adults are staying overnight.
• Spade rudder requires careful inspection for moisture and internal wear.
