The boat is typically equipped with an inboard Perkins diesel engine at 135.0 hp (100 kW), which gives a max speed about 7.8 knots.
The fuel tank has a capacity of 1000.0 liters (264 US gallons, 219 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.
What is Capsize Screening Formula (CSF)?
The capsize screening value for Contest 55 CS is 1.61, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.
Contest 55 CS holds one CE certification:
The boat is by European Union certified as Class A. OCEAN:What is Theoretical Maximum Hull Speed?
The theoretical maximal speed of a displacement boat of this length is 8.9 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.
The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for Contest 55 CS is about 422 kg/cm, alternatively 2363 lbs/inch.
Meaning: if you load 422 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 2363 lbs cargo on the boat it will sink 1 inch.

What is L/B (Length Beam Ratio)?
The l/b ratio for Contest 55 CS is 3.60.
What is Displacement Length Ratio?
The DL-ratio for Contest 55 CS is 277 which categorizes this boat among 'medium weight cruisers'.
SA/D (Sail Area Displacement ratio)
Indicates how fast the boat is in light wind:
- Cruising Boats have ratios 10-15
- Cruiser-Racers have ratios 16-20
- Racers have ratios above 20
- High-Performance Racers have ratios above 24
Sail-area/displacement ratio (SA/D ratio): 19.31
