Cockpit of Vindö 40 anno 1979.
The boat equipped with a masthead rig. The advantage of a masthead rig is its simplicity and the fact that a given sail area - compared with a fractional rig - can be carried lower and thus with less heeling moment.
The boat is typically equipped with an inboard Volvo Penta MD2B engine at 25.0 hp (18 kW), which gives a max speed about 5.4 knots.
The fuel tank has a capacity of 40 liters (10 US gallons, 8 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 Vindö 40 is 1.72, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.
Theoretical Maximum Hull Speed
What is Theoretical Maximum Hull Speed?
The theoretical maximal speed of a displacement boat of this length is 6.6 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 Vindö 40 is about 148 kg/cm, alternatively 830 lbs/inch.
Meaning: if you load 148 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 830 lbs cargo on the boat it will sink 1 inch.
