What is Capsize Screening Formula (CSF)?
The capsize screening value for CNB 66 is 1.77, 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 10.4 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.
The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for CNB 66 is about 681 kg/cm, alternatively 3814 lbs/inch.
Meaning: if you load 681 kg cargo on the boat then it will sink 1 cm.
