Design and Construction
The hull is solid fiberglass, and the deck likewise is solid fiberglass rather than cored construction. With a length overall of just over 31 feet and a beam near 11.2 feet, the hull form is slender — the length-to-beam ratio sits at 2.63 — which, together with a displacement of roughly 8,150 pounds and a 36 percent ballast ratio, places the design among what performance indices describe as light racers, with a DL-ratio of 173. The wetted surface area is about 333 square feet. A notable structural flexibility is the availability of two keel alternatives: a fin keel drawing about 5.6 to 5.9 feet depending on load, and a drop keel that retracts to roughly 1.4 to 1.7 feet, letting the boat reach shallow marinas that a fixed-fin version cannot different keel alternatives. The iron keel and solid-glass build reflect a straightforward, certifiable ocean-capable structure rather than a weight-optimized racing shell.
Rig and Handling
The fractional sloop carries a working sail area of about 431 square feet for mainsail and jib, and the mast stands roughly 48 feet above the waterline. The design's performance numbers are telling: a capsize screening value of 2.35 means it would not qualify for ocean racing under that rule, while a Motion Comfort Ratio of 15.7 and an immersion rate near 1,020 pounds per inch describe a boat that responds readily to load changes but is not a heavy-passage motorship. The theoretical displacement-hull speed is 6.9 knots, and the Relative Speed Performance index is pegged at 100, marking it as a reasonably quick coastal and offshore cruiser in its size band capsize screening value.
Accommodations
Below, the Tango 30 is laid out for a sizable crew relative to its length: six primary berths plus two additional, a galley, a toilet compartment, and about 53 gallons of fresh water capacity. Headroom is above average for the class, which makes the interior more livable than the slender hull might suggest. The combination of berth count and stowage supports extended cruising for a small family or a racing crew rotating off-watch.
Power and Specifications
A Yanmar 3YM20 inboard diesel of about 21 horsepower may be fitted, driving the boat at a recorded 7.0 knots under power — slightly above the theoretical hull speed, consistent with a light-displacement hull. Fuel capacity is 18 gallons. The CE Class A Ocean certification indicates the boat was approved for extended voyages where conditions may exceed those of sheltered waters, a meaningful statement for a 31-foot series-built design CE certification.
The Verdict
The Tango 30 is a compact, certifiable ocean-capable cruiser with a light-racer's turn of speed and a surprisingly roomy interior for its slender beam. The choice between fin and drop keel lets a buyer prioritize either stability and upwind bite or shallow-water access, and the solid fiberglass construction keeps the structure uncomplicated. Its low production count makes it a relatively uncommon find, but the design metrics show a coherent small-boat cruiser rather than a compromised racer.
Pros
- CE Class A Ocean certification for extended voyages
- Drop-keel option opens shallow marinas and anchorages
- Above-average headroom and 6+2 berths for the length
- Light-displacement performance with 7-knot powered speed
Cons
- Capsize screening value of 2.35 excludes ocean racing
- Fewer than 100 built, limiting fleet support and parts commonality
- Slender hull and 36% ballast ratio favor performance over load-carrying comfort
