Hull
The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.

Interior
The boat is equipped with 0 cabins and 4-6 berths.
The headroom is above average

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.

Keel

The boat can only enter major marinas as the draft is about 2.14 - 2.24 meter (7.02 - 7.32 ft) dependent on the load. See immersion rate below.


Engine

Bavaria Vision 46 is typically equipped with an inboard Volvo Penta D2-55 diesel engine at 55.0 hp (40 kW), which gives a max speed about 6.9 knots.

The transmission is a saildrive.

The fuel tank has a capacity of 210.0 liters (55 US gallons, 46 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 Bavaria Vision 46 is 1.83, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.


EU classification

Bavaria Vision 46 holds two CE certifications:

If less than 10 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.

If less than 16 in on board the boat is by European Union certified as Class B. OFFSHORE:
Designed for offshore voyages where conditions up to, and including, wind force 8 (Beaufort scale) and significant wave heights up to, and including, 4 m may be experienced.


Theoretical Maximum Hull Speed

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 8.7 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 Bavaria Vision 46 is about 360 kg/cm, alternatively 2016 lbs/inch.
Meaning: if you load 360 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 2016 lbs cargo on the boat it will sink 1 inch.

Maintenance

Bottom Paint

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 61m2 (656 ft2).
Based on this, your favourite maritime shop can tell you the quantity you need.

Note: If you use a paint roller you will need more paint than if you use a paintbrush.
