Interior

The boat is equipped with 2 cabins, 5 berths, a galley, 400.0 liter fresh water capacity and toilet facility.


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 Naut 33 is 2.05, indicating that this boat would not be accepted to participate in ocean races.


Theoretical Maximum Hull Speed

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 7.4 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 Naut 33 is about 201 kg/cm, alternatively 1130 lbs/inch.
Meaning: if you load 201 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1130 lbs cargo on the boat it will sink 1 inch.
