Hull
The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season. And outside the sailing season, just bottom cleaning and perhaps anti-fouling painting once a year - a few hours of work, that's all.

Interior
The interior is like most other boats made of teak.
The boat is equipped with 2 cabins, 4-5 berths, a galley and toilet facility.

Rig

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.

Keel

The Vindö 30 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.

The keel is made of lead. Compared with iron, lead has the advantage of being 44% heavier, which allows a smaller keel and hence less water resistance and higher speed.

The boat can enter even shallow marinas as the draft is just about 1.30 - 1.40 meter (4.27 - 4.57 ft) dependent on the load. See immersion rate below.


Engine

Vindö 30 is typically equipped with an inboard Volvo Penta MD11C diesel engine at 27.0 hp (20 kW), which gives a max speed about 6.7 knots.

The fuel tank has a capacity of 25.0 liters (6 US gallons, 5 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 Vindö 30 is 1.63, 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 6.5 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 Vindö 30 is about 116 kg/cm, alternatively 652 lbs/inch.
Meaning: if you load 116 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 652 lbs cargo on the boat it will sink 1 inch.


Sailing statistics

This section is statistical comparison with similar boats of the same category. The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.

Motion Comfort Ratio

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Vindö 30 is 29.2.

Low High 82% 0 50 100
Comparing this ratio with similar sailboats show that it is more comfortable than 82% of all similar sailboat designs. This is a comfort value significantly above average.


L/B (Length Beam Ratio)

What is L/B (Length Beam Ratio)?

The l/b ratio for Vindö 30 is 3.71.

Wide Slim 96% 0 50 100
Compared with other similar sailboats it is slimmer than 96% of all other designs. It seems that the designer has chosen a significantly more speedy hull design. This type of design is also referred to as 'needle'.


Ballast Ratio

What is a Ballast Ratio?

The ballast ratio for Vindö 30 is 40%.

Low High 46% 0 50 100
This ballast ratio shows a righting moment that is higher than 46% of all similar sailboat designs. A righting moment (ability to resist heeling) just below average.


D/L (Displacement Length Ratio)

What is Displacement Length Ratio?

The DL-ratio for Vindö 30 is 272 which categorizes this boat among 'light crusers & offshore racers'.

Heavy Light 42% 0 50 100
42% of all similar sailboat designs are categorized as heavier. A heavy displacement combined with smaller water plane area has lower acceleration and is more comfortable.


SA/D (Sail Area Displacement ratio)

What is SA/D (Sail Area Displacement ratio)?

The SA/D for Vindö 30 with ISO 8666 reference sail is 14.1, with a 135% genua the SA/D is 16.6.

Low High 27% 0 50 100
The SA/D ratio indicates that it is faster than 27% of all similar sailboat designs in light wind.


Over- / underrigged

Low High 76% 0 50 100
The Vindö 30 has more rig than 76% of all similar sailboats, which indicates that the boat is significantly overrigged.


RSP (Relative Speed Performance)

What is Relative Speed Performance?

The Relative Speed Performance for Vindö 30 is 4

Slow Fast 4% 0 50 100
The relative speed performance is 4 which means that a it is faster than 4% of all similar sailboat designs.


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 20m2 (215 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.
