Unknown keel type

Skorpion I A can enter most marinas as the draft is just about 1.50 - 1.60 meter (4.92 - 5.22 ft) dependent on the load. See immersion rate below.


Engine

The boat may be equipped with an inboard engine

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


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 Skorpion I A is 1.67, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.


Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Skorpion I A is about 199 kg/cm, alternatively 1116 lbs/inch.
Meaning: if you load 199 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1116 lbs cargo on the boat it will sink 1 inch.
