Bonita 767 Information, Review, Specs

Sailing Performance & Handling

Under sail, the Bonita 767 is defined by its impressive stiffness, a direct result of a ballast ratio approaching 48%. With a displacement of approximately 2,100 kg and nearly half of that weight concentrated in its iron fin keel, the boat possesses a high righting moment that allows it to carry its sail plan longer than many of its contemporaries. Technical data verified by the German Sailing Association (DSV) suggests a Yardstick handicap of approximately 106 to 109, placing it firmly in the category of "moderate racers."

The fractional sloop rig provides a versatile setup, typical of Jeppesen’s design philosophy. With a standard Sail Area to Displacement (SA/D) ratio of roughly 16.8, the boat is responsive in light airs, though it truly excels in a breeze. The spade rudder offers precise, fingertip control, though sailors accustomed to full-keel vessels may find the tracking slightly more active. The hull’s displacement-to-length ratio (DLR) of 218 categorizes it as a medium-displacement vessel, ensuring it maintains momentum through a chop—a characteristic often cited in Danish racing archives as a key strength for Baltic Sea conditions.

Interior Comfort & Variations

Despite its modest 7.67-meter (25-foot) length, the interior of the Bonita 767 is remarkably dense with accommodation, typically offering five to six berths. The layout is optimized for family cruising, featuring a V-berth forward, two settees in the main salon, and often a quarter berth tucked under the cockpit. The use of GRP sandwich construction in both the hull and deck provides exceptional thermal and acoustic insulation, a feature that significantly reduces condensation in colder climates.

The materials used in the cabinetry are predominantly teak veneers over marine plywood, reflecting the high standard of Danish craftsmanship. Variations of the model exist, most notably the choice between a standard fin keel and a shallow-draft variant designed for the shoal waters of the Dutch and German coasts. While the "Bonita" branding was often used for specific export markets, the structural components and interior layout remain identical to the standard Granada 767 models.

Popular Mentions & Media

The Bonita 767’s primary claim to fame is its pedigree. As an early work of Niels Jeppesen, it is frequently discussed in historical retrospectives of Danish naval architecture. While it lacks a major Hollywood footprint, it is a staple of European sailing literature, often appearing in technical comparisons within "Bådmagasinet" (Denmark) and "Die Yacht" (Germany) as a benchmark for 1980s pocket cruiser design. Its enduring popularity in the European "Yardstick" racing scene ensures it remains a well-documented model in regional racing databases.

Known Issues & Buyer’s Checklist

Prospective buyers should focus on three primary technical areas characteristic of this build period:

1. Keel Attachment and Iron Oxidation: The 767 utilizes an iron fin keel. Over time, the protective epoxy coating can fail, leading to "rust blooming." Inspect the keel-to-hull joint for any signs of weeping or structural stress (the "smile" at the leading edge), which can indicate loose keel bolts or compression issues.
2. Deck Core Integrity: Because the deck is a sandwich construction (often using balsa or foam), any improperly sealed deck hardware—such as stanchion bases or traveler tracks—can allow water to penetrate the core. Potential buyers should use a moisture meter or perform a percussion test (tapping) to check for delamination.
3. Spade Rudder Bearings: The spade rudder is efficient but prone to bearing wear. Excessive "play" or a heavy feeling in the tiller often points to the need for new bushings or a check of the internal rudder post for electrolysis.
4. Rigging Tension: As a fractional rig with swept-back spreaders, the mast requires proper pre-bend and stay tension to perform correctly. Older rigs may show signs of wire fatigue at the swage fittings.

Community & Resources

The most active technical resources for the Bonita 767 are found through European-based owner networks. Technical specifications and handicap data are maintained by the Swiss Sailing Yardstick Authority, which provides historical performance benchmarks. While no single English-language "Bonita Club" exists, owners typically congregate under the umbrella of broader Granada Yachts or Niels Jeppesen design forums, where technical wikis often cover maintenance of the Jeppesen-designed series (the 767, 858, and 939).

The Verdict

The Bonita 767 is a sophisticated, "over-engineered" pocket cruiser that offers the performance of a modern racer with the build quality of a classic Scandinavian yacht.

Pros:

• Exceptional stability and stiffness due to a 48% ballast ratio.
• High-quality GRP sandwich construction provides superior insulation.
• Prestigious design pedigree (Niels Jeppesen).
• Spacious interior for its length, capable of sleeping five.

Cons:

• Iron keel requires more diligent maintenance than lead.
• Sandwich core is vulnerable to water ingress if deck fittings are neglected.
• Relatively high displacement makes it less suitable for high-speed planing compared to modern sportboats.
