Review of Tango 30

Basic specs.

The Tango 30 is a sailboat designed by the Polish maritime architect Andrzej Skrzat in the mid 2000. Less than 100 boats have been produced. The Tango 30 is built by the Polish yard Tango Yacht.

Here we would have liked to show you nice photos of the Tango 30.

Hull

The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season. And outside the sailing season, just bottom cleaning and perhaps anti-fouling painting once a year - a few hours of work, that's all.

Interior

The boat is equipped with 6+2 berths, a galley and toilet facility.
The headroom is above average

Rig

The boat equipped with a fractional rig. A fractional rig has smaller headsails which make tacking easier, which is an advantage for cruisers and racers, of course. The downside is that having the wind from behind often requires a genaker or a spinnaker for optimal speed.

Keel

The Tango 30 is equipped with a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a long keel.

The boat can enter even shallow marinas as the draft is just about 0.42 - 0.52 meter (1.38 - 1.68 ft) dependent on the load. See immersion rate below.

Engine

Tango 30 is typically equipped with an inboard Yanmar 3YM20 diesel engine at 21.0 hp (15 kW), which gives a max speed about 6.6 knots.

The fuel tank has a capacity of 70.0 liters (18 US gallons, 15 imperial gallons).

Sailing characteristics

This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.

Stability and Safety

What is Capsize Screening Formula (CSF)?

The capsize screening value for Tango 30 is 2.35, indicating that this boat would not be accepted to participate in ocean races.

EU classification

Tango 30 holds one CE certification:

The boat is by European Union certified as Class A. OCEAN:

Designed for extended voyages where conditions may exceed wind force 8 (Beaufort scale) and significant wave heights of 4 m and above but excluding abnormal conditions, and vessels largely self-sufficient.

Theoretical Maximum Hull Speed

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 6.9 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.

Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Tango 30 is about 182 kg/cm, alternatively 1020 lbs/inch.
Meaning: if you load 182 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1020 lbs cargo on the boat it will sink 1 inch.

Sailing statistics

This section is statistical comparison with similar boats of the same category. The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.

Motion Comfort Ratio

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Tango 30 is 15.7.

Comparing this ratio with similar sailboats show that it is more comfortable than 14% of all similar sailboat designs. This is a comfort value significantly below average.

L/B (Length Beam Ratio)

What is L/B (Length Beam Ratio)?

The l/b ratio for Tango 30 is 2.63.

Compared with other similar sailboats it is more spacy than 90% of all other designs. It seems that the designer has chosen a significantly more spacy hull design.

Ballast Ratio

What is a Ballast Ratio?

The ballast ratio for Tango 30 is 36%.

This ballast ratio shows a righting moment that is higher than 24% of all similar sailboat designs. A righting moment (ability to resist heeling) significantly below average.

D/L (Displacement Length Ratio)

What is Displacement Length Ratio?

The DL-ratio for Tango 30 is 172 which categorizes this boat among 'light racers'.

85% of all similar sailboat designs are categorized as heavier. A light displacement requires less sailarea and has higher accellerations.

RSP (Relative Speed Performance)

What is Relative Speed Performance?

The Relative Speed Performance for Tango 30 is 100

The relative speed performance is 100 which means that a it is faster than 100% of all similar sailboat designs.

Maintenance

Bottom Paint

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 31m² (333 ft²).
Based on this, your favourite maritime shop can tell you the quantity you need.

Note: If you use a paint roller you will need more paint than if you use a paintbrush.

Rig

If you need to renew parts of your running rig and is not quite sure of the dimensions, you may find the estimates computed below useful.
