The boat is equipped with 3 cabins, 6 berths, a galley and 132.0 liter waste water capacity.

Rig

Keel

The boat can only enter major marinas as the draft is about 1.98 - 2.08 meter (6.50 - 6.80 ft) dependent on the load. See immersion rate below.

Engine

Hans Christian Christina 43 is typically equipped with an inboard Yanmar 4JH2-TE diesel engine at 57.0 hp (42 kW), which gives a max speed about 6.0 knots.

The transmission is a shaft drive. A shaft drive will in the long run require less maintenence than other types of drive e.g. a sail drive.

The fuel tank which is made of stainless steel has a capacity of 378.0 liters (99 US gallons, 83 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.

Stability and Safety

What is Capsize Screening Formula (CSF)?

The capsize screening value for Hans Christian Christina 43 is 1.70, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

EU classification

Hans Christian Christina 43 holds one CE certification:

The boat is by European Union certified as Class A. OCEAN:

Designed for extended voyages where conditions may exceed wind force 8 (Beaufort scale) and significant wave heights of 4 m and above but excluding abnormal conditions, and vessels largely self-sufficient.

Theoretical Maximum Hull Speed

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 7.9 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 Hans Christian Christina 43 is about 290 kg/cm, alternatively 1628 lbs/inch.
Meaning: if you load 290 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1628 lbs cargo on the boat it will sink 1 inch.
