Hull
Both the hull and the deck 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 6 berths, a galley and toilet facility.
Note: the boat has also been sold to be self-made/-interiored, which means that the quality of each boat may vary.

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 Drabant 38 is equipped with 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 keel is made of iron. Many people prefer lead keel in favour of iron. The main argument is that lead is much heavier than iron and a lead keel can therefore be made smaller which again result in less wet surface, i.e. less drag. In fact iron is quite heavy, just 30% less heavy than lead, so the advantage of a lead keel is often overstated. As the surface of a fin type keel is just a fraction of the total wet surface, the difference between an iron keel and a lead keel can in reality be ignored for cruising yachts.

Drabant 38 can only enter major marinas as the draft is about 1.92 - 2.02 meter (6.30 - 6.60 ft) dependent on the load. See immersion rate below.


Engine

The boat is typically equipped with an inboard Yanmar 3GMC diesel engine at 22.0 hp (16 kW), which gives a max speed about 5.9 knots.

The transmission is a saildrive.

The fuel tank which is made of stainless steel has a capacity of 30.0 liters (7 US gallons, 6 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 Drabant 38 is 1.81, 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 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 Drabant 38 is about 188 kg/cm, alternatively 1057 lbs/inch.
Meaning: if you load 188 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1057 lbs cargo on the boat it will sink 1 inch.

What is a Ballast Ratio?

The ballast ratio for Drabant 38 is 38%.

Low High 42% 0 50 100
This ballast ratio shows a righting moment that is higher than 42% 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 Drabant 38 is 152 which categorizes this boat among 'light racers'.

Heavy Light 88% 0 50 100
88% of all similar sailboat designs are categorized as heavier. A light displacement requires less sailarea and has higher accellerations.


RSP (Relative Speed Performance)

What is Relative Speed Performance?

The Relative Speed Performance for Drabant 38 is 76

Slow Fast 76% 0 50 100
The relative speed performance is 76 which means that a it is faster than 76% 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 35m2 (376 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.
