The Allures 51.9 is equipped with a centerboard keel. A centerboard keel is a pivoting lifting keel, allowing to sail both coastal and inland waters.
The boat can enter even shallow marinas as the draft is just about 1.34 - 1.44 meter (4.40 - 4.70 ft) dependent on the load. See immersion rate below.
Allures 51.9 is typically equipped with an inboard engine at 110.0 hp (81 kW).
The fuel tank has a capacity of 700.0 liters (184 US gallons, 153 imperial gallons).
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.
