The Waarschip 660 represents a pivotal moment in the evolution of the Dutch "plywood revolution" of the 1970s. Designed by Klaas Kremer and introduced as a successor to the popular Waarschip 600, the 660 was engineered to provide a more voluminous interior and improved stability while maintaining the brand's signature clinker-built aesthetic. Constructed primarily from marine plywood bonded with epoxy, the 660 occupies a unique space between a spirited club racer and a coastal family cruiser. It was frequently delivered as a "self-build" kit, a factor that has led to a high degree of variability in finish quality across the second-hand market. According to the historical archives at Waarschip.info, the model was designed to offer "more boat" than its predecessor without losing the agility required for the shallow, choppy waters of the IJsselmeer and the Wadden Sea.

Sailing Performance & Handling
The sailing characteristics of the Waarschip 660 are defined by its high ballast ratio and its distinctive multi-chine hull. With a total weight of approximately 1,100 kg and nearly 450 kg of that concentrated in the keel, the 660 is exceptionally stiff for a 21-foot vessel. This rigidity allows it to carry full sail longer than many GRP (glass-reinforced plastic) competitors of the same era. The hull's "clinker" steps act as longitudinal stringers, providing additional lift and shedding spray effectively, which results in a remarkably dry cockpit even when beating into a chop.
Under sail, the 660 is known for its "honest" feedback; it tracks well thanks to its deep fin keel (typically drawing 1.00m or 1.25m) but remains responsive enough for single-handed maneuvering. While it lacks the raw surfing potential of the more radical Waarschip 725 Quarter Tonner, the 660 offers a more forgiving motion. The rig is a standard 7/8ths fractional setup, which allows for precise mainsail trimming to control heel in gusty conditions. Owners often report that the boat feels "bigger" than its 6.6-meter length would suggest, handling offshore coastal hops with a level of sea-kindliness usually reserved for 28-footers.
Interior Comfort & Variations
Despite its modest waterline, the Waarschip 660 utilizes its 2.50-meter beam to create a surprisingly functional living space. The interior is characterized by the warmth of varnished wood, a stark contrast to the "white plastic" interiors of contemporary mass-produced boats. The layout typically features a classic V-berth forward, which is partitioned from the main saloon by a bulkhead that often houses a small chemical toilet or storage lockers.
The main cabin consists of two longitudinal settees that double as berths, bringing the total sleeping capacity to four. A compact galley area is usually situated near the companionway, featuring a simple two-burner stove and a small sink. Because many 660s were finished by their original owners, interior cabinetry and wood choices (teak vs. mahogany veneers) vary significantly. The "Standard" version of the 660 focused on cruising utility, while the "High Aspect" variants often featured upgraded deck hardware to suit more competitive sailors. It is important to note the 660's siblings: the smaller Waarschip 570, which offers more basic day-sailing accommodations, and the Waarschip 700, which eventually replaced the 660 by offering increased headroom and a modernized hull shape.
Known Issues & Buyer’s Checklist
The primary concern for any prospective Waarschip 660 buyer is the integrity of the plywood hull and deck. While epoxy-saturated plywood is incredibly strong and light, it is susceptible to "creeping rot" if the protective coating is breached.
- The "Bak" (Hull Bottom): Inspect the area around the keel attachment point. Freshwater that sits in the bilge can penetrate the plywood end-grain if the epoxy seal has been compromised by keel movement or grounding.
- Deck-to-Hull Join: Examine the toe rail and the deck edge. These areas are prone to leaks which can rot the structural frames. Look for dark staining or "soft spots" in the wood.
- Rudder Post and Bearings: The 660 uses a transom-hung or spade rudder depending on the specific sub-build; ensure there is no delamination in the rudder blade itself, which is a common failure point in older wooden composites.
- Chainplates: Check the areas where the stays meet the deck. If water has leaked through the chainplate fittings, it can rot the main bulkhead, which is a labor-intensive structural repair.
Community & Resources
The legacy of the 660 is preserved by a very active community of enthusiasts, primarily centered in Northern Europe. The most prominent resource is the Waarschip Owners Association (Waarschippers), which maintains an extensive technical library and organizes annual "Waarschip Week" regattas. This association is the primary source for original building plans and advice on modern epoxy restoration techniques specific to the 660's clinker construction.
The Verdict
The Waarschip 660 remains a "sailor’s sailboat," offering a level of tactile feedback and aesthetic charm that modern production boats rarely match. While it requires more maintenance than a fiberglass hull, its performance-to-price ratio is difficult to beat for those willing to pick up a varnish brush.
Pros:
- Exceptional stability and stiffness due to a high ballast ratio.
- Warm, traditional wooden aesthetic that ages gracefully.
- Strong, active owner community provides excellent technical support.
- Easily trailered compared to heavier keelboats of the same displacement.
Cons:
- Requires consistent maintenance of the epoxy and paint systems to prevent rot.
- Limited standing headroom (typical for boats under 7 meters).
- Build quality varies significantly depending on the original kit builder’s skill.
