Design and Construction
The hull and deck are both solid fiberglass rather than cored construction. Length overall is just over 31 feet, with a beam near 11.2 feet and a length-to-beam ratio of 2.63. Displacement is roughly 8,150 pounds, the ballast ratio is 36 percent, and wetted surface area is about 333 square feet.
Together, these figures place the Tango 30 among what performance indices describe as light racers. Its DL-ratio is 173. Even so, the iron keel and solid-glass construction reflect a straightforward, certifiable ocean-capable structure rather than a weight-optimized racing shell.
The boat was offered with different keel alternatives. The fin keel draws about 5.6 to 5.9 feet, depending on load. The drop keel retracts to roughly 1.4 to 1.7 feet, allowing the boat to enter shallow marinas that the fixed-fin version cannot.
Rig, Performance, and Handling
The fractional sloop carries about 431 square feet of working sail area between the mainsail and jib. Its mast stands roughly 48 feet above the waterline.
The performance figures describe a relatively light, responsive boat. A capsize screening value of 2.35 means the Tango 30 wouldn’t qualify for ocean racing under that rule. Its Motion Comfort Ratio is 15.7, while an immersion rate near 1,020 pounds per inch suggests a boat that responds readily to changes in load but isn’t a heavy-passage motorship.
The theoretical displacement-hull speed is 6.9 knots. A Relative Speed Performance index of 100 marks the Tango 30 as a reasonably quick coastal and offshore cruiser in its size band.
Accommodations
The Tango 30 accommodates a sizable crew for its length, with six primary berths plus two additional berths. The interior also includes a galley, a toilet compartment, and about 53 gallons of fresh-water capacity.
Headroom is above average for the class, making the interior more livable than the slender hull might suggest. The berth count and available stowage support extended cruising for a small family or a racing crew rotating off-watch.
Engine and Tankage
A Yanmar 3YM20 inboard diesel of about 21 horsepower may be fitted. The boat has recorded 7.0 knots under power, slightly above its theoretical hull speed and consistent with a light-displacement hull. Fuel capacity is 18 gallons.
The Tango 30’s CE Class A Ocean certification indicates that it was approved for extended voyages where conditions may exceed those found in sheltered waters—a meaningful statement for a 31-foot, series-built design.
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 of fin or drop keel allows a buyer to prioritize either stability and upwind bite or access to shallow water. Solid-fiberglass construction keeps the structure uncomplicated.
With fewer than 100 boats built, the Tango 30 is a relatively uncommon find. Even so, its design metrics describe a coherent small-boat cruiser rather than a compromised racer.
Pros
- CE Class A Ocean certification for extended voyages
- Drop-keel option provides access to shallow marinas and anchorages
- Above-average headroom and 6+2 berths for its length
- Light-displacement performance and a recorded 7-knot speed under power
Cons
- Capsize screening value of 2.35 excludes it from ocean racing under that rule
- Fewer than 100 built, limiting fleet support and parts commonality
- Slender hull and 36 percent ballast ratio favor performance over load-carrying comfort
