sail specifications
The Omega 30 is a sailboat designed by the New Zealander maritime architect Ron Holland in the early eighties. A few hundred boats have been produced. The Omega 30 is built by the Swedish yard Svenska Familjebåtar AB.

Hull

Both the hull and the deck 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.
Unfortunately, the hull is not a double hull which affects the indoor climate. Especially if the water is considerable colder than the cabin, then one might expect condense water in the cabin.
The deck is a double deck which improves the indoor climate.


Interior
Interior
Interior of Omega 30 anno 1986. Omega 30 A

The interior is like many other boats made of mahogany. Mahogany belongs to the hardwood species, known for being water-repellent and resistant to decay. It has an attractive wood grain and holds wood polish and varnish well.
The boat is equipped with 5-6 berths, a galley, 71.0 liter fresh water capacity and toilet facility.


Rig

The Omega 30 is 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 gennaker or a spinnaker for optimal speed.


Keel

Fin keel

The Omega 30 is equipped with a fin keel. The fin keel is the most common keel and provides splendid manoeuvrability. The downside is that it has less directional stability than a long keel.

The keel is made of iron. Many people prefer lead keel in favour of iron. The main argument is that lead is much heavier than iron and a lead keel can therefore be made smaller which again result in less wet surface, i.e. less drag. In fact iron is quite heavy, just 30% less heavy than lead, so the advantage of a lead keel is often overstated. As the surface of a fin type keel is just a fraction of the total wet surface, the difference between an iron keel and a lead keel can in reality be ignored for cruising yachts.

The boat can enter most marinas as the draft is just about 1.55 - 1.65 meter (5.09 - 5.39 ft) dependent on the load. See immersion rate below.


Engine

The Omega 30 has been equipped with different engine alternatives.

Alternative 1:

Omega 30 may be equipped with an inboard Yanmar 2GM20 diesel engine

Alternative 2:

The boat may be equipped with an inboard Yanmar 1GM10 diesel engine at 8 hp (5 kW). The speed is 6.0 knots.

The fuel tank, which is made of stainless steel, has a capacity of 25.0 liters (6 US gallons, 5 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 Omega 30 is 2.01, indicating that this boat would not be accepted to participate in ocean races.


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 Omega 30 is about 160 kg/cm, alternatively 900 lbs/inch.
Meaning: if you load 160 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 900 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 Omega 30 is 19.8.

Low High 27% 0 50 100
Comparing this ratio with similar sailboats show that it is more comfortable than 27% of all similar sailboat designs. This comfort value is just below average.


L/B (Length Beam Ratio)

What is L/B (Length Beam Ratio)?

The l/b ratio for Omega 30 is 3.13.

Slim Wide 50% 0 50 100
Compared with other similar sailboats it is more spacy than 50% of all other designs. It seems that the designer has chosen an average hull design.


Ballast Ratio

What is a Ballast Ratio?

The ballast ratio for Omega 30 is 39%.

Low High 38% 0 50 100
This ballast ratio shows a righting moment that is higher than 38% of all similar sailboat designs. A righting moment (ability to resist heeling) just below average.


D/L (Displacement Length Ratio)

What is Displacement Length Ratio?

The DL-ratio for Omega 30 is 185 which categorizes this boat among 'light racers'.

Heavy Light 79% 0 50 100
79% of all similar sailboat designs are categorized as heavier. A light displacement requires less sailarea and has higher accellerations.


SA/D (Sail Area Displacement ratio)

What is SA/D (Sail Area Displacement ratio)?

The SA/D for Omega 30 with ISO 8666 reference sail is 18.9, with a 135% genua the SA/D is 21.8.

Low High 82% 0 50 100
The SA/D ratio indicates that it is faster than 82% of all similar sailboat designs in light wind.


Over- / underrigged

Low High 95% 0 50 100
The Omega 30 has more rig than 95% of all similar sailboats, which indicates that the boat is significantly overrigged.


RSP (Relative Speed Performance)

What is Relative Speed Performance?

The Relative Speed Performance for Omega 30 is 82

Slow Fast 82% 0 50 100
The relative speed performance is 82 which means that a it is faster than 82% 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 27m2 (290 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.
