Northshore 340 Information, Review, Specs

Sailing Performance & Handling

Under sail, the Northshore 340 exhibits the classic hallmarks of a Tony Castro design: it is well-balanced, stiff, and notably fast for its class. The boat utilizes a 7/8 fractional rig with a large mainsail and a relatively small, easy-to-tack jib, making it an ideal choice for short-handed crews. The hull profile is sleek, featuring a fine entry that slices through chop and a clean exit that minimizes drag in light airs.

With a Displacement/Length ratio typically in the "light-moderate" category for cruisers of its era, the 340 is responsive to trim changes. Owner accounts and historical commentary from Tony Castro Design suggest that the boat is particularly rewarding on a beat, where the deep lead bulb keel provides a high righting moment, allowing the vessel to carry full sail longer than its competitors. The steering is generally described as light and direct, providing the helmsperson with excellent feedback, a trait often missing in the more "detached" feel of the heavier Southerly models.

Interior Comfort & Variations

Inside, the Northshore 340 benefits from the high-caliber joinery for which the Itchenor-based yard was famous. The layout is a conventional but highly effective two-cabin arrangement. The use of warm teak or cherry veneers—depending on the specific hull's commission—contrasts with the modern, white GRP moldings to create a space that feels both traditional and bright.

The saloon features twin longitudinal settees with a central folding table, while the L-shaped galley is positioned to port, offering a high degree of security when preparing meals at sea. One of the standout features for a 34-foot boat is the size of the aft cabin and the heads compartment; Northshore utilized the boat's beam effectively to ensure these areas do not feel cramped. In comparison to its siblings, the Northshore 310 is significantly more constrained in the aft quarters, while the Northshore 380 introduces a larger navigation station and increased storage for long-distance voyaging.

Known Issues & Buyer’s Checklist

While the Northshore 340 is built to a high standard, there are specific areas potential buyers should investigate during a survey:

1. Saildrive Diaphragm: Most 340s were fitted with Volvo Penta engines and saildrives. The rubber sealing diaphragm has a recommended replacement interval (typically 7 years). Buyers should verify the age of this seal, as failure can lead to catastrophic water ingress.
2. Rudder Bearings: Given the performance nature of the boat, the rudder takes significant loads. Reports of play in the upper or lower bearings are not uncommon in older models, which can lead to vibration or "clunking" at the helm.
3. Deck Hardware Sealing: Like many boats from the 90s, the 340 features a sandwich construction deck. Any leaks from stanchion bases or tracks that have not been re-bedded can lead to moisture in the core. A moisture meter check around high-load areas is essential.
4. Rigging Age: As many of these boats were used for occasional club racing, the standing rigging may have been stressed more than a dedicated coastal cruiser. If the rigging is over 10 years old, a full replacement should be factored into the purchase price.

Community & Resources

Owners of the Northshore 340 often find a home within the broader Northshore Owners Association. While the association is heavily weighted toward the Southerly and Vancouver brands, the technical expertise regarding Northshore’s GRP layup techniques and interior finishes remains highly relevant. Additionally, the Tony Castro Design office maintains archives for many of their classic performance hulls, which can be a vital resource for technical drawings or original specifications.

The Verdict

The Northshore 340 is a "sailor’s sailboat," offering a rare blend of British build quality and Mediterranean performance flair. It is a distinctive choice for those who want the prestige of the Northshore name without the weight and complexity of a swing-keel system.

Pros

• Exceptional Build Quality: Built during an era when Northshore was at the peak of its craftsmanship.
• Superior Handling: A true performance cruiser that excels in upwind performance and light-wind agility.
• Timeless Aesthetics: Sleek lines that have aged significantly better than the "high-volume" production boats of the same era.

Cons

• Rarity: Far fewer 340s were built compared to the Southerly range, making them difficult to find on the secondhand market.
• Draft Limitations: Unlike its Southerly cousins, the fixed fin keel precludes entry into very shallow estuaries.
• Cockpit Depth: The cockpit is designed for active sailing and may feel slightly less protected in heavy following seas compared to a dedicated blue-water cruiser.
