Interior

The boat is equipped with a galley and toilet facility.

Rig

The boat equipped with a ketch rig.

Keel

The Vindö 90 has been built with more than one type of keel.

One option is a long keel. A long keel provide a better directional stability than a similar boat with a fin keel; on the other hand, better directional stability means also that the boat is more difficult to handle in a harbour with less space.

Another option is a fin keel. The fin keel is the most common keel and provides splendid manoeuvrability. The downside is that it has less directional stability than a long keel.

The boat can enter most marinas as the draft is just about 1.75 - 1.85 meter (5.74 - 6.04 ft) dependent on the load. See immersion rate below.

Engine

Vindö 90 is typically equipped with a diesel engine.

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 Vindö 90 is 1.74, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Vindö 90 is about 344 kg/cm, alternatively 1926 lbs/inch.
Meaning: if you load 344 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1926 lbs cargo on the boat it will sink 1 inch.
