Kievit 680 Information, Review, Specs

Constructed entirely of Glass Reinforced Plastic (GRP), the model was part of a lineage that included the larger Kievit 820, which shared much of the same design DNA but offered more substantial accommodation for extended cruising. The 680 remains a common sight in Dutch and German marinas, favored by solo sailors and small families for its simplicity and forgiving nature.

Sailing Performance & Handling

The sailing characteristics of the Kievit 680 are defined by its high ballast-to-displacement ratio, which reportedly approaches 50%. This creates a "stiff" boat that carries its canvas well into freshening breezes, often continuing to sail comfortably when lighter contemporary vessels of a similar size are forced to reef. Most models feature an S-shaped hull (S-spant) with an integrated keel, which contributes to excellent directional stability and a predictable, dampened motion in a seaway.

According to technical discussions within the Dutch sailing community, specifically on platforms such as Zeilersforum, the boat is widely regarded as a "slow but steady" performer. While it may struggle to find its pace in light airs (under 8 knots), it excels in moderate to heavy winds where its momentum and grip on the water allow it to track better than many modern fin-keel boats. The standard sail plan is relatively conservative, usually consisting of a high-aspect jib or genua and a slab-reefing mainsail. Handling is straightforward via a transom-hung rudder and tiller, making it an ideal platform for those learning the fundamentals of sail trim and heavy-weather tactics.

Interior Comfort & Variations

The interior of the Kievit 680 is optimized for short-term cruising, offering a traditional four-berth layout that was standard for the "pocket cruiser" era. The cabin features a classic V-berth in the bow, separated from the main salon by a small bulkhead or privacy curtain. In the salon, two longitudinal settees double as single berths. Despite the boat's modest 2.3-meter beam, the use of space is efficient, typically including a small slide-out galley or a dedicated area for a two-burner spirit stove and a compact sink.

Headroom is limited—a common trade-off for the boat's sleek, low-profile coachroof—making it more suitable for "sitting headroom" living. Materials are generally functional, featuring a mix of molded GRP liners and mahogany or teak trim. Variations in the model are primarily found in the engine configurations; while many were delivered with an outboard motor in a dedicated well or on a transom bracket, a rare "Deluxe" version was equipped with a small inboard diesel, such as the single-cylinder Farymann or Viry units.

Known Issues & Buyer’s Checklist

Prospective buyers of a Kievit 680 should prioritize a thorough hull inspection, as these boats were built during an era when fiberglass technology was still maturing.

• Osmotic Blistering: The most frequently cited technical concern for the Kievit 680 is osmosis. Reports from Dutch boatyards suggest that certain production years were more susceptible to hull blistering than others. A survey should include moisture meter readings, particularly around the turn of the bilge and the keel-to-hull transition.
• Deck Core Integrity: Like many vessels of this vintage, the deck may utilize a balsa or foam core. Inspect for "soft spots" or delamination, particularly around high-load fittings like the chainplates, stanchion bases, and the mast step.
• Rudder Hardware: The transom-hung rudder is a simple design, but the pintles and gudgeons are prone to wear and play. Check for any lateral movement in the rudder stock or stress cracks in the transom fiberglass where the hardware is mounted.
• Keel Profile: Some owners have noted that the original factory finish of the S-shaped keel can be uneven. Refinement of the keel profile (template-sanding) is a common project for owners looking to improve upwind performance and reduce drag.

Community & Resources

The Kievit 680 enjoys a dedicated following, particularly in its home waters. The Zeilersforum (Netherlands) serves as the primary technical repository for the model, where owners share restoration logs, original sail plans, and advice on converting outboard wells. While a standalone international class association does not exist, the boat is often represented within broader "Classic GRP" enthusiast groups in Northern Europe.

The Verdict

The Kievit 680 is a rugged, overbuilt cruiser that prioritizes safety and stability over outright speed, making it an excellent choice for budget-conscious sailors who frequent coastal waters.

Pros

• Exceptional stability due to a high ballast ratio.
• Predictable handling and excellent tracking in heavy weather.
• Simple, robust systems that are easy for the DIY owner to maintain.
• Very affordable entry price on the second-hand market.

Cons

• Relatively sluggish performance in light wind conditions.
• Limited interior headroom for taller sailors.
• High prevalence of osmosis in original, untreated hulls.
• Age-related wear in deck cores and rigging is common.
