Manta 19 Information, Review, Specs

Sailing Performance & Handling

The Manta 19 is characterized by its high stability-to-weight ratio, a necessity for the unpredictable winds of its native Austrian lakes. Most models feature a swing-keel (Hubkiel) configuration, which reduces the draft from nearly a meter to just 45 centimeters, allowing for effortless beaching and shallow-water exploration. Under sail, the boat is known for its forgiving nature; it tracks reasonably well for a short-waterline vessel, though it lacks the pointing ability of a modern racing dinghy.

The Miglitsch hull design incorporates a relatively wide beam of 2.00 meters relative to its 5.70-meter length, providing a stable platform that resists excessive heeling. While it is not a high-performance flyer, the Manta 19 is often described by owners as a "stiff" boat that handles heavy air better than many contemporary 19-footers. The rigging is typically a simple fractional sloop setup, designed for ease of use by a single-handed sailor or a small family. Editorial retrospectives in German maritime media often highlight the vessel's "sea-kindliness" on inland waters, noting that its displacement of approximately 750kg provides enough momentum to punch through the short, choppy waves common on the Lake of Constance or the Chiemsee.

Interior Comfort & Variations

Despite its modest 19-foot length, the Manta 19 was marketed as a "micro-cruiser" capable of overnighting. The interior layout is surprisingly functional, featuring a V-berth forward and two narrow quarter berths extending aft under the cockpit seats. While the shipyard theoretically rated the boat for four occupants, practical use suggests it is best suited for two adults or a young family.

The cabin offers sitting headroom, which was a significant selling point in the late 60s compared to the "coffin-like" interiors of pure racing boats. The use of mahogany trim against the white GRP interior reflects the Schöchl family's origins as master carpenters. Variations of the model exist primarily in the keel configuration; while the swing-keel version is most common for its trailering benefits, a fixed-keel version was also produced for sailors who prioritized stiffness and did not require frequent road transport. Additionally, the Manta 18 is often cited as a smaller sibling, though the 19 is widely considered the more balanced and successful evolution of the design.

Known Issues & Buyer’s Checklist

Prospective buyers of a Manta 19 should focus their inspection on three primary areas critical to GRP boats of this vintage:

1. Swing-Keel Mechanism: The cast-iron keel is operated by a stainless steel cable and winch system. Inspect the pivot bolt for wear and the cable for fraying. If the boat has been kept in the water for long periods, the keel trunk can accumulate marine growth or rust, preventing the keel from retracting fully.
2. Rudder Gudgeons: The transom-mounted rudder is a high-stress point. Check for hairline cracks in the gelcoat around the gudgeons and ensure the pintles are not bent. Owners frequently report that older rudders may take on water if the seal between the GRP halves has degraded.
3. Deck Core and Soft Spots: While Schöchl’s build quality was high, 50-year-old sandwich decks can suffer from moisture ingress, particularly around the mast step and the chainplates. Use a phenolic hammer to check for dull thuds that indicate delamination.
4. Window Seals: The original acrylic windows were often secured with rubber gaskets that perish over decades. Leaking windows are the most common cause of interior wood rot in these vessels.

Community & Resources

The Manta 19 enjoys a dedicated following, particularly within the German-speaking sailing community. The most prominent technical resource is the Manta 19 IG (Interessengemeinschaft), a group of owners who maintain archives of original brochures, rigging diagrams, and restoration guides. Because the boat was built by the same family that still operates Sunbeam Yachts, technical queries are occasionally supported by the factory, which maintains a deep respect for its heritage fleet.

The Verdict

The Manta 19 is a quintessential entry-level cruiser that offers a bridge between dinghy sailing and "big boat" yachting. It remains an excellent choice for sailors who value build quality and trailability over modern aesthetics or high-speed planing performance.

Pros:

• High Build Quality: Superior GRP lay-up and wood finishing compared to many mass-produced 70s cruisers.
• Easy Trailering: The lightweight design and swing-keel make it manageable for standard SUVs.
• Stability: A very safe and predictable hull for beginners or families.

Cons:

• Age: Almost all units will require some level of restoration to rigging or seals.
• Interior Space: While it has four berths, they are cramped for multi-day trips with more than two adults.
• Speed: Lacks the performance of modern sport-boats in light wind conditions.
