Hull

The hull is made of hand laid fibreglass while the deck is made of fibreglass. Generally, a hull made of hand laid 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.

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

Rig

The boat equipped with a masthead rig. The advantage of a masthead rig is its simplicity and the fact that a given sail area - compared with a fractional rig - can be carried lower and thus with less heeling moment.

Keel

The Mermaid 290 has been built with more than one type of keel.

One option is 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 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.

The boat can enter even shallow marinas as the draft is just about 1.35 - 1.45 meter (4.43 - 4.73 ft) dependent on the load. See immersion rate below.

Engine

Mermaid 290 is typically equipped with an inboard Volvo Penta engine at 18.0 hp (13 kW), which gives a max speed about 5.3 knots.

The transmission is a saildrive.

The fuel tank which is made of stainless steel has a capacity of 70.0 liters (18 US gallons, 15 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 Mermaid 290 is 1.84, 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 6.6 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 Mermaid 290 is about 144 kg/cm, alternatively 807 lbs/inch.

Meaning: if you load 144 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 807 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 24m^{2} (258 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.
