Design and Construction
Streuer's Phantom 30 is a product of the early-1970s German yacht industry, when solid fiberglass layups were still being built generously thick because nobody fully trusted the material's long-term behavior. The hull and deck are fiberglass, with the early Genzel hulls laid up as solid GRP rather than cored. The fin keel carries 3,086 pounds of ballast, and the rudder is hung from a partial skeg ahead of its trailing edge. At a beam of 9.32 feet on 30.51 feet overall, the yacht is slimmer than 62 percent of comparable designs, giving her an length-to-beam ratio of 3.21 that reads as a narrow, purposeful hull rather than a volume-maximized coastal cruiser. The wetted surface of the underwater body is about 258 square feet, and the immersion rate runs roughly 978 pounds per inch, so she settles predictably under load without dramatic trim changes.
Rig and Handling
The masthead-sloop rig drives a reported 376.74 square feet of sail, and the running rigging dimensions are well documented: jib and genoa sheets run about 30 feet at a half-inch diameter, the mainsheet is 75 feet of the same 12-millimeter line, and spinnaker sheets are 66 feet. With a fin keel and skeg-hung rudder, the boat tracks with the directional stability a partial skeg confers without the drag of a full keel. Her draft is about 4.43 feet unloaded and can reach 4.73 feet under load, shallow enough to tuck into modest marinas while preserving the lateral bite a fin gives to windward work. The 24.28-foot waterline and 6.6-knot hull speed define the pace she can sustain before wavemaking dominates.
Accommodations
Below, the Phantom 30 sleeps four across berths and carries a galley, with 6.23 feet of headroom that reviewers place near the average for the class. That standing room and the four-berth count come from a hull only 9.32 feet abeam, so the interior volume is honest rather than expansive — the slim beam that helps her sailing profile necessarily limits cabin width. The galley and berth arrangement serve a small crew on coastal passages without pretending to be a voluminous liveaboard.
Known Issues
The early solid-GRP hulls were built thick out of period uncertainty, and the rudder is supported on a partial skeg rather than fully protected. A buyer should understand that the boat's age places her in a cohort where original deck hardware, engine mounts, and through-hulls are decades old, but the sources attach no specific failure mode to this design.
Refits and Ownership
Ownership of a Phantom 30 means living with a 1970s Streuer cruiser whose production ended in 1978 after a few hundred were built. The simple masthead rig with standard sheet diameters makes running-rigging renewal straightforward, and the solid fiberglass hull avoids the cored-deck moisture paths that plague some contemporaries. Her modest 4.43-foot draft keeps yard and marina options open, and the predictable 978-pounds-per-inch immersion means load planning is intuitive for a couple or small family cruising.
The Verdict
The Phantom 30 is a thoughtfully proportioned early-Seventies cruiser-racer: narrow for her length, solidly built in GRP, and rigged simply enough for an owner to maintain. Streuer gave her a fin keel and partial-skeg rudder that balance agility with directional steadiness, and the four-berth interior is practical if not roomy. She is a credible used-classic candidate for a sailor who values a well-documented, limited-production German design over a high-volume production boat.
Pros
- Slim 3.21 length-to-beam ratio; narrower than 62% of comparable sailboats
- Solid fiberglass construction with early thick layups
- Fin keel with partial-skeg rudder for tracking and shallow-draft access
- Simple masthead rig with standard 12 mm sheet diameters throughout
Cons
- 9.32-foot beam limits interior volume despite four berths
- Production ended in 1978; all hulls are decades old
