The boat is equipped with a galley, 1500.0 liter fresh water capacity, toilet facility and 360.0 liter waste water capacity.
Note: the boat has also been sold to be self-made/-interiored, which means that the quality of each boat may vary.
The boat equipped with a ketch rig. A ketch rig is generally considered easier to handle, because the sails are smaller, and because it can sail on most points to the wind with one sail completely taken down for repair or while reefing. The sail configuration of a ketch allows for better comfort and stability when sailing downwind or on a broad reach.
Unknown keel type
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.
Motiva 57 can only enter major marinas as the draft is about 2.10 - 2.20 meter (6.89 - 7.19 ft) dependent on the load. See immersion rate below.
The boat is typically equipped with an inboard Perkins engine at 130 hp (96 kW). Calculated max speed is about 6.9 knots
The fuel tank has a capacity of 1800.0 liters (475 US gallons, 395 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.
What is Capsize Screening Formula (CSF)?
The capsize screening value for Motiva 57 is 1.53, 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 9.2 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 Motiva 57 is about 459 kg/cm, alternatively 2575 lbs/inch.
Meaning: if you load 459 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 2575 lbs cargo on the boat it will sink 1 inch.

When buying anti-fouling bottom paint, it's nice to know how much to buy.
The surface of the wet bottom is about 74m2 (796 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.
