The Shark 50 has been built with different keel alternatives.
Deep keel
One option is a deep keel. A deep keel provide a better healing moment than a shallow keel.
The keel is made of lead. Compared with iron, lead has the advantage of being 44% heavier, which allows a smaller keel and hence less water resistance and higher speed.
The boat can only enter major marinas as the draft is about 2.20 - 2.30 meter (7.22 - 7.52 ft) dependent on the load. See immersion rate below.
Shallow keel
Another option is a shallow keel. A shallow keel allow to sail both coastal and inland waters.
The keel is made of lead. Compared with iron, lead has the advantage of being 44% heavier, which allows a smaller keel and hence less water resistance and higher speed.
The boat can enter most marinas as the draft is just about 1.60 - 1.70 meter (5.25 - 5.55 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.
The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for Shark 50 is about 400 kg/cm, alternatively 2242 lbs/inch.
Meaning: if you load 400 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 2242 lbs cargo on the boat it will sink 1 inch.
