Jongert 16S Information, Review, Specs

Sailing Performance & Handling

The sailing characteristics of the Jongert 16S are dictated by its significant displacement—often exceeding 30 tons depending on the specific fit-out. As a heavy-displacement cruiser, the boat exhibits a high level of directional stability and a remarkably soft motion in a seaway. While it lacks the "twitchy" responsiveness of modern composite cruisers, it excels in "tracking," meaning it holds its course with minimal helm correction once the sails are balanced.

The ketch rig is central to the 16S’s handling philosophy. By splitting the sail area between two masts, Jongert allowed smaller crews to manage the boat effectively, as each individual sail is smaller and easier to winch or reef than those on a comparably sized sloop. Under sail, the 16S requires a stiff breeze—typically 12 knots or more—to truly wake up. Once moving, its momentum allows it to punch through choppy head seas that would stall lighter vessels. Owners frequently report that the boat feels most at home on a reach or a run, where the mizzen sail can be used to fine-tune the balance of the helm, often allowing the autopilot to work with minimal strain.

Interior Comfort & Variations

True to the Jongert pedigree, the interior of the 16S is a showcase of traditional Dutch cabinetry, typically finished in high-grade teak or mahogany. The layout usually centers around a semi-raised deck saloon or a protected wheelhouse, providing excellent visibility and a social hub that remains dry even in foul weather. Because Jongert operated as a semi-custom yard, variations exist; however, the standard configuration typically includes a voluminous master aft cabin—often featuring the iconic stern windows—and guest V-berths forward.

The 16S shares its hull DNA and design philosophy with several siblings in the "S" and "T" (Traditional) lines. The Jongert 17S and 19S offer expanded versions of this platform, with the 17S providing slightly more waterline length for improved hull speed. Unlike the more modern "M" (Modern) series, the 16S maintains a classic feel with deep bilges and a traditional galley-down arrangement that provides security for the cook while underway. Headroom is generous throughout, usually exceeding 6'4" in the main saloon, a testament to the boat’s volume-heavy design.

Known Issues & Buyer’s Checklist

Prospective buyers of a Jongert 16S must approach the purchase with an understanding of steel hull maintenance. While Jongert’s steelwork is legendary for its robustness, age is the primary adversary.

• Hull Corrosion & Ultrasonic Testing: It is imperative to conduct a full ultrasonic thickness survey of the hull. Particular attention should be paid to the "dead zones" in the bilges under tanks or engines where moisture can sit undetected, leading to interior-to-exterior corrosion.
• Teak Deck Longevity: Many 16S models were built with thick teak decks bedded in compounds or occasionally screwed into the sub-deck. Over decades, these seams can fail. Replacing a full teak deck on a vessel of this complexity is a significant capital expense.
• System Complexity: Jongert yachts are known for their sophisticated (for the time) hydraulic and electrical systems. Original wiring and plumbing may now be nearing the end of its reliable lifespan and may require a phased refit to meet modern safety standards.
• Stainless-to-Steel Transitions: Inspect the areas where stainless steel fittings (like stanchion bases or bitts) meet the mild steel deck. If the isolation has failed, galvanic corrosion can cause bubbling of the paint and pitting of the metal.

Community & Resources

The primary hub for technical data and historical records is the Jongert Shipyard archive, which maintains a degree of continuity for its heritage fleet. Owners often congregate through the Jongert Owners Club, a semi-formal association that organizes rallies and shares technical knowledge regarding the specific engineering challenges of maintaining these Dutch classics.

The Verdict

The Jongert 16S is a "ship" in the truest sense of the word, built for those who value the journey as much as the destination. It is not a boat for the casual weekend racer, but for the circumnavigator, it remains one of the most prestigious and secure platforms ever built.

Pros:

• Indestructible Build: The steel hull and over-engineered fittings offer unparalleled peace of mind in heavy weather.
• Luxury Finish: The quality of the interior joinery is significantly higher than contemporary mass-produced yachts.
• Sea-Kindliness: A heavy, stable motion that minimizes crew fatigue during long passages.

Cons:

• Maintenance Intensity: Steel requires constant vigilance regarding paint and corrosion prevention.
• Light Air Performance: The high displacement-to-length ratio makes the boat sluggish in winds under 10 knots.
• Draft Constraints: The deep keel necessary for such a heavy boat limits access to some shallow cruising grounds and bahamian-style anchorages.
