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.

The deck is a double deck which improves the indoor climate.

The deck is a double deck which improves the indoor climate.

Interior

The interior is like most other boats made of teak.

The boat is equipped with 4-6 berths, a galley and toilet facility.

Note: the boat has also been sold to be self-made/-interiored, which means that the quality of each boat may vary.

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 Omega 42 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 keel is made of lead. Compared with iron, lead has the advantage of being 44% heavier, which allows a smaller keel and hence less water resistance and higher speed.

Omega 42 can enter most marinas as the draft is just about 1.67 - 1.77 meter (5.48 - 5.78 ft) dependent on the load. See immersion rate below.

Engine

The boat is typically equipped with an inboard Yanmar diesel engine at 20.0 hp (14 kW), which gives a max speed about 4.7 knots.

The transmission is a shaft drive. A shaft drive will in the long run require less maintenence than other types of drive *e.g.* a sail drive.

The fuel tank which is made of stainless steel has a capacity of 50.0 liters (13 US gallons, 10 imperial gallons).

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 42 is 1.60, indicating that this boat could - if evaluated by this formula alone - 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 7.7 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 42 is about 207 kg/cm, alternatively 1163 lbs/inch.

Meaning: if you load 207 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 1163 lbs cargo on the boat it will sink 1 inch.

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 36m^{2} (387 ft^{2}).

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.
