The boat is equipped with 6 cabins and 1264.0 liter fresh water capacity.
The Jeanneau 64 has been built with different keel alternatives.
Unknown keel type
The keel is made of iron. Many people prefer lead keel in favour of iron. The main argument is that lead is much heavier than iron and a lead keel can therefore be made smaller which again result in less wet surface, i.e. less drag. In fact iron is quite heavy, just 30% less heavy than lead, so the advantage of a lead keel is often overstated.
The boat can only enter major marinas as the draft is about 2.95 - 3.05 meter (9.68 - 9.98 ft) dependent on the load. See immersion rate below.
Wing keel
But be aware that even though a Wing Keel keel is very good for speed racing, a fishing nets and the like in the water can easily make you into a troublesome situation.
This keel is also made of iron.
Jeanneau 64 can only enter major marinas as the draft is about 2.20 - 2.30 meter (7.22 - 7.52 ft) dependent on the load. See immersion rate below.
The boat may be equipped with an inboard Volvo Penta D4-180 diesel engine at 180 hp (134 kW). Calculated max speed is about 9.3 knots
The fuel tank has a capacity of 825.0 liters (217 US gallons, 181 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 Jeanneau 64 is 1.73, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.
Jeanneau 64 holds a CE certification:
The boat is by European Union certified as Class A. OCEAN:What is Theoretical Maximum Hull Speed?
The theoretical maximal speed of a displacement boat of this length is 10.3 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 Jeanneau 64 is about 651 kg/cm, alternatively 3646 lbs/inch.
Meaning: if you load 651 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 3646 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 113m2 (1216 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.
