The boat can enter even shallow marinas as the draft is just about 1.27 - 1.37 meter (4.17 - 4.47 ft) dependent on the load. See immersion rate below.
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.
The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for First Class Challenge is about 198 kg/cm, alternatively 1113 lbs/inch.
Meaning: if you load 198 kg cargo on the boat then it will sink 1 cm.
