Hull

The hull is made of fibreglass while the deck is made of hand laid fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.

Interior

The interior is like nearly all boats made of wood.
The boat is equipped with 2 cabins, 6 berths, a galley and toilet facility.

Rig

The boat equipped with a fractional rig. A fractional rig has smaller headsails which make tacking easier, which is an advantage for cruisers and racers, of course. The downside is that having the wind from behind often requires a genaker or a spinnaker for optimal speed.

Engine

The boat is typically equipped with an inboard Yanmar 3GM30, SD20 diesel engine at 27.0 hp (20 kW), which gives a max speed about 5.6 knots.

The transmission is a saildrive.

The fuel tank which is made of steel has a capacity of 80 liters (21 US gallons, 17 imperial gallons).

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.

Stability and Safety

What is Capsize Screening Formula (CSF)?

The capsize screening value for Winner 1120 is 1.93, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

EU classification

Winner 1120 holds one CE certification:

If less than 6 in on board the boat is by European Union certified as Class A. OCEAN:

Designed for extended voyages where conditions may exceed wind force 8 (Beaufort scale) and significant wave heights of 4 m and above but excluding abnormal conditions, and vessels largely self-sufficient.

Theoretical Maximum Hull Speed

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 7.4 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.

Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Winner 1120 is about 224 kg/cm, alternatively 1256 lbs/inch.
Meaning: if you load 224 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1256 lbs cargo on the boat it will sink 1 inch.
