The boat is equipped with 360.0 liter fresh water capacity.
The Maxi 380+ 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.
Unknown keel type
The boat can only enter major marinas as the draft is about 2.00 - 2.10 meter (6.56 - 6.86 ft) dependent on the load. See immersion rate below.
Maxi 380+ may be equipped with an inboard Volvo Penta MD22L diesel engine at 48 hp (35 kW). Calculated max speed is about 7.7 knots
The transmission is a saildrive.
The fuel tank has a capacity of 200.0 liters (52 US gallons, 43 imperial gallons).

What is Capsize Screening Formula (CSF)?
The capsize screening value for Maxi 380+ is 1.91, indicating that this boat could - if evaluated by this formula alone - 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 8.2 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.

Meaning: if you load 288 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 1617 lbs cargo on the boat it will sink 1 inch.

Maintenance
When buying anti-fouling bottom paint, it's nice to know how much to buy.
The surface of the wet bottom is about 50m2 (538 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.
