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.
The boat is equipped with 38.0 liter fresh water capacity.
The Mirage 27 is 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.
The boat may be equipped with an inboard Yanmar 1GM diesel engine at 9 hp (6 kW). Calculated max speed is about 4.4 knots
The fuel tank has a capacity of 45.0 liters (11 US gallons, 9 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.
What is Capsize Screening Formula (CSF)?
The capsize screening value for Mirage 27 is 2.10, indicating that this boat would not be accepted to participate in ocean races.
What is Theoretical Maximum Hull Speed?
The theoretical maximal speed of a displacement boat of this length is 6.2 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.
The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for Mirage 27 is about 123 kg/cm, alternatively 692 lbs/inch.
Meaning: if you load 123 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 692 lbs cargo on the boat it will sink 1 inch.
