The vessel was conceived as an accessible but seaworthy family cruiser capable of navigating the tidal shallows of the Wadden Sea, the choppy waters of the IJsselmeer, and coastal estuaries. Van der Rest’s focus on durability and stable handling set the model apart from lighter, more tender French and German competitors of the era. The success of the design laid the groundwork for the builder's later lines, which were rebranded under the "Piewiet" moniker in 1977. Decades after production ceased, the original molds were sold to Harpol in Harlingen, which marketed a modernized version known as the Kievit 22 until the mid-2000s.
Design Brief & Interior Accommodations
The primary design mandate of the Kievit 680 was to pack genuine cruising utility and physical comfort into a hull under 23 feet. While contemporaries like the Etap 22 forced taller sailors to compromise on sleeping and sitting room, Van der Rest utilized a deeper, ruder hull form to optimize the interior envelope.
The layout features four fixed berths, including a remarkably spacious V-berth in the bow and two expansive quarter berths—locally referred to as hondenkooien—that extend to an impressive two meters in length, allowing tall adults to sleep comfortably. The joinery is simple, functional, and warm, featuring traditional marine plywood and solid wood trims.
A defining feature of many Kievit 680 hulls is the optional pop-top cabin roof (hefdak). While the standard cabin provides a modest headroom of 1.60 meters, extending the pop-top increases headroom to a highly functional 1.80 meters at the companionway. This configuration transforms a cramped weekend cabin into an airy, livable space with excellent ventilation. This makes the boat a favorite among cruisers who prefer to spend extended periods on board without the logistical footprint of a larger vessel.
Sailing Performance & Handling
At the helm, the Kievit 680 is characterized by its stability, predictable tracking, and "stiff" behavior in heavy air. Constructed with a robust fiberglass layup, the monohull design relies on a traditional semi-S-framed hull section transitioning to a deep fin keel with a draft of approximately 1.12 to 1.15 meters. Its length-to-beam (L/B) ratio of 2.93 reveals a slightly slimmer hull profile than average for early pocket cruisers, which helps it slice through chop rather than pounding over it.
The masthead sloop rig carries an aluminum mast and a balanced sail plan of approximately 25 square meters. The rig is typically paired with a 10-square-meter mainsail and a 15-square-meter head sail, frequently managed via a roller furling system.
While not a light-air racer, the Kievit 680 carries its canvas exceptionally well as the breeze freshens. The deep, protected cockpit with high coamings keeps the crew dry and secure. Tiller steering provides direct feedback, and the single, transoms-hung rudder offers ample authority, though she will carry a slight weather helm when over-canvased, serving as a natural cue to reef the main.
Propulsion & Configuration
The propulsion layout of the Kievit 680 is highly distinct, featuring an outboard motor mounted within an integrated well—or bun—inside the cockpit rather than on a standard transom bracket. This design choice keeps the outboard protected from waves, dampens engine noise, and keeps the controls within easy reach of the helmsman.
The boat is typically powered by a long-shaft outboard motor ranging from 6 to 12 horsepower, with 8-horsepower units being the most common choice among veteran owners. While this configuration isolates the motor and preserves the classic lines of the transom, it does introduce hydrodynamic drag, as the lower unit of the outboard remains immersed even while sailing.
Additionally, the restricted airflow within the bun can cause exhaust gases to pool. This is particularly noticeable on older two-stroke outboards, occasionally letting fumes seep into the cockpit or cabin.
Known Issues & Triage
Given the vintage of these vessels, prospective buyers must watch for several documented age-related issues.
- Osmotic Blistering: Early Dutch fiberglass layups are highly robust but susceptible to osmosis. Hulls that have spent consecutive seasons in fresh or brackish water often require a thorough peel, dry-out, and epoxy barrier-coat treatment.
- Keel Joint Seepage: The transition where the cast-iron ballast keel meets the fiberglass stub can develop minor weeping or rust staining. Owners should inspect the internal keel bolts for corrosion and ensure the external joint is properly ground out and sealed.
- Motor Well Ventilation: The bun configuration can suffer from poor ventilation. Over time, fuel lines or exhaust seals can degrade, causing fume issues. Veteran owners often resolve this by running a dedicated flexible exhaust hose from the outboard directly through a retrofitted port in the transom.
- Deck Core Wetness: While the hull is solid fiberglass, the deck utilizes a balsa or marine plywood core which can suffer from rot around high-load hardware, such as chainplates and mast steps, if the sealant has been neglected.
Modernization & Upgrades
Many current owners actively refit these pocket cruisers to keep them modern and simple to sail solo.
- Electrical Systems and LiFePO4: The original electrical panels are often upgraded to modern marine wiring harnesses paired with small lithium-iron-phosphate (LiFePO4) house banks, easily maintained by a single deck-mounted solar panel.
- Mast-Lowering Gear: Because these boats are highly popular on European canals and inland lakes, many owners install custom mast-lowering systems (maststrijkinstallatie). These setups feature double A-frames or a hinged mast step, allowing the mast to be safely dropped while underway to clear low bridges.
- Electric Outboard Conversion: The well-protected engine bun makes the Kievit 680 an ideal candidate for electric propulsion conversions. Upgrading to a pod-style or drop-in electric outboard resolves the common issues of exhaust fumes, carburetor maintenance, and fuel storage in the cabin.
The Verdict
The Kievit 680 remains a standout classic in the pocket-cruiser category. It is highly regarded for its sea-kindly hull shape, dense build quality, and clever interior design that accommodates taller sailors far better than its size suggests. While it lacks the speed of modern sportboats, its robust construction and sheltered cockpit make it an exceptionally forgiving platform for beginners and a reliable single-handed cruiser for seasoned sailors.
Pros:
- Extremely sturdy hull and deck construction with high resistance to structural flexing.
- Unusually long quarter berths and excellent sitting headroom, especially on models equipped with the pop-top roof.
- Outboard-in-well (bun) design protects the engine from sea state and places controls within easy reach.
- High initial stability and forgiving handling characteristics in choppy coastal waters.
Cons:
- Increased drag under sail due to the outboard leg remaining submerged in the well.
- Potential for exhaust gas accumulation inside the cockpit well when using older gasoline outboards.
- Age-related vulnerability to hull osmosis requiring dry-dock inspection.
- Heavy displacement relative to modern trailer-sailers makes launching and retrieving from a ramp more challenging.
