Piewiet 850 Information, Review, Specs

Sailing Performance & Handling

The design influence of Koos de Ridder is evident in the Piewiet 850’s balanced hull form and predictable handling characteristics. Carrying a masthead sloop rig, the boat is generally regarded as "stiff," meaning it resists excessive heeling in moderate breezes, providing a sense of security for family cruisers. While not a dedicated racing machine, its sailing ratios suggest a respectable displacement-to-length profile that allows it to maintain momentum in choppy coastal conditions.

Owners often report that the boat tracks exceptionally well, a trait attributed to its semi-skeg-protected rudder and moderate fin keel. In editorial retrospectives by Dutch sailing publications such as Zeilen, the 850 is often praised for its "Zeewaardigheid" (seaworthiness), specifically its ability to handle the short, steep chop of the IJsselmeer without slamming. The deck layout is functional, though the original cockpit ergonomics reflect the era's preference for high coamings to keep the crew dry, rather than the expansive lounging areas found on modern equivalents.

Interior Comfort & Variations

For a vessel of 8.5 meters, the Piewiet 850 offers a remarkably practical and voluminous interior. The layout typically features a classic V-berth forward, a central saloon with two longitudinal settees that double as sea berths, and a quarter berth to starboard. A significant selling point during its production was the standing headroom, which reaches approximately 1.82 meters (6 feet) in the main cabin, a feat for a boat of this length.

The woodwork is traditionally finished in teak or mahogany veneers, reflecting the high standard of Dutch craftsmanship of the period. The galley is usually located to port of the companionway, equipped with a two-burner stove and a deep sink. While the 850 remained the core of the mid-range lineup, its hull design shared DNA with the slightly smaller Piewiet 820, though the 850 utilized the extra length to improve the navigation station and head compartment. Some later versions featured a revised "Mk II" interior with updated materials and more efficient storage lockers, though the structural bulkheads remained consistent throughout the production run.

Known Issues & Buyer’s Checklist

Prospective buyers should approach the Piewiet 850 with a focus on its age-related maintenance. Technical discussions within Dutch owner circles highlight several key areas for inspection:

• Osmosis Protection: Like many GRP boats from the late 1970s, the Piewiet 850 can be susceptible to osmotic blistering if the gelcoat has not been properly maintained or if an epoxy barrier coat was never applied.
• Window Leaks: The original aluminum-framed windows are known to develop leaks over time as the sealant dries out. This can lead to localized damage to the interior wood veneers.
• Engine Maintenance: Many units were originally fitted with Farymann or older Yanmar diesel engines. Buyers should verify if the engine has been repowered or if the cooling system shows signs of heavy salt-water corrosion.
• Deck Core: While the hull is solid, the deck may utilize a sandwich construction. Soft spots near the mast step or chainplates should be checked with a moisture meter to ensure the core has not been compromised by water ingress.

Community & Resources

The primary hub for technical data and social gathering for this model is the Piewiet Club, a dedicated association for owners of Van de Rest-built vessels. This group maintains a repository of historical documentation and provides a forum for discussing restoration projects and specific rigging modifications.

The Verdict

The Piewiet 850 remains a highly regarded choice for sailors seeking a robust, budget-friendly coastal cruiser with a pedigree of Dutch engineering. While it may lack the contemporary styling of modern yachts, its build quality and predictable sea-kindliness make it a dependable partner for offshore passages.

Pros:

• Exceptional build quality and structural rigidity.
• Predictable and forgiving handling in heavy weather.
• Generous headroom and interior volume for its class.
• Strong resale value within Northern European markets.

Cons:

• Dated interior aesthetics compared to modern light-filled cabins.
• Original engine and systems likely require significant investment if not already updated.
• Cockpit space can feel cramped when sailing with a full crew of four or more.
