Keel

Unknown keel type

The boat can enter most marinas as the draft is just about 1.76 - 1.86 meter (5.77 - 6.07 ft) dependent on the load. See immersion rate below.

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.

Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Impala is about 161 kg/cm, alternatively 905 lbs/inch.
Meaning: if you load 161 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 905 lbs cargo on the boat it will sink 1 inch.
