Design and Construction
The Javelin 38 was built predominantly of solid fiberglass with wood trim. Her profile includes a spooned, raked stem and a raised counter ending in a plumb transom.
Below the waterline is a fixed lead fin keel. Its 4,760 pounds of ballast, set against a displacement of 16,000 pounds, produces a 30-percent ballast ratio and places a clear emphasis on righting moment rather than lightweight construction.
A displacement-length ratio of 457 puts the Javelin 38 among ultra-heavy cruisers. She is also narrow by modern standards, with a 10-foot beam and a length-to-beam ratio of 3.78. Her waterline length is 25 feet. A capsize screening value of 1.59 and Motion Comfort Ratio of 39.6 point to a hull intended to carry its crew through weather rather than dance around a buoy course.
Rig and Handling
Tripp offered more than one rig. Documented choices include a masthead sloop and a yawl. The standard sailplan is a Bermuda-rigged masthead sloop, with 577 square feet of sail area. Against the boat’s 16,000-pound displacement, that gives a sail-area-displacement ratio of 15.95—modest and consistent with the hull’s heavy-cruiser character.
The control lines were sized for manual handling. Jib and genoa sheets are 37.8 feet long and half an inch in diameter. The mainsheet is 94.6 feet long, while the spinnaker sheet is 83.2 feet; both are 14 mm.
With about 290 square feet of wetted surface and an immersion rate of 871 pounds per inch, the Javelin sits deep and moves her waterline reluctantly. Her theoretical displacement hull speed is 6.7 knots, while a calculated maximum near 5.1 knots frames her as a passage-maker rather than a sprinter. Draft ranges from 5.25 to 5.55 feet, depending on load, keeping her within most marina approaches.
Accommodations and Systems
The Javelin 38 is a cruiser and recreational keelboat, but the sources don’t itemize berth numbers, galley arrangements, or head layouts. Those details must therefore be assessed hull by hull during an inspection.
The documented service envelope includes 35 gallons of gasoline for a single 20-horsepower Universal Atomic 4 engine and 100 gallons of water. Steering is through a skeg-hung rudder paired with the fin-keel hull form.
Wood trim gives the interior a period look rather than the all-fiberglass modular cabins found in later production boats. Specific details of the joinery, stowage, and livability fall outside the recorded facts.
Known Issues
The available record identifies no structural defects, osmotic blistering, rigging failures, or systemic construction faults. Even so, the history of each boat must be established by survey. A documented osmosis repair, chainplate re-bedding, or fuel-tank replacement shouldn’t be assumed from the type’s record.
Refits and Ownership
Owning a Javelin 38 means looking after one of roughly two dozen surviving Dutch cruisers, many of which crossed to the United States through Seafarer Yachts.
The gasoline-powered Atomic 4 is a period engine, and its care differs from modern diesel practice. The solid-fiberglass hull and wood trim also invite the usual half-century refit cycle, including fastener renewal, rig inspection, and finish work on the trim.
Because a yawl rig was optional, some boats carry a mizzen and have a different sail-handling profile from the masthead-sloop majority. Buyers should confirm the rig before making assumptions about spar and winch inventory.
The Verdict
The Javelin 38 is a serious small-series cruiser from the early Tripp-Lentsch collaboration. She is heavy, narrow, and ballasted with lead, with a documented stability profile and a choice of sloop or yawl rig. By modern numbers she isn’t a performance boat, but her construction record is clean and her proportions are those of a vessel designed to go offshore rather than win Wednesday-night races.
Pros
- Lead fin keel, 30-percent ballast ratio, and a capsize screening value of 1.59
- Solid-fiberglass hull with wood trim, built by a documented Dutch yard
- Offered with a masthead sloop or yawl rig to suit owner preference
- Ultra-heavy-cruiser displacement-length ratio of 457, favoring offshore comfort
Cons
- Modest sail-area-displacement ratio of 15.95 limits light-air pace
- Gasoline-powered Atomic 4 rather than a diesel, with period-specific maintenance needs
- Only about 25 built, so comparable boats and spares are scarce
