Both the hull and the deck is made of hand laid fibreglass. Generally, a hull made of hand laid 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.
The interior is like most other boats made of teak. Teak has the advantage of being naturally very oily and therefore water-repellent, which is suitable on boats.
The boat is equipped with one cabin, a galley and 140.0 liter fresh water capacity.
The S2 9.2A is 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 S2 9.2A has been built with different keel alternatives.
Fin keel
One option is a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a full keel.
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 1.49 - 1.59 meter (4.89 - 5.19 ft) dependent on the load. See immersion rate below.
Fin keel
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 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.
S2 9.2A can enter even shallow marinas as the draft is just about 1.19 - 1.29 meter (3.90 - 4.20 ft) dependent on the load. See immersion rate below.
The S2 9.2A has been equipped with different engine alternatives.
Alternative 1:
The boat may be equipped with an inboard Yanmar 2GM20F diesel engine at 18 hp (13 kW). Cruise speed is 6.0 knots.
Alternative 2:
The boat may be equipped with an inboard Yanmar 2GM diesel engine at 15 hp (11 kW). Calculated max speed is about 4.6 knots
The fuel tank has a capacity of 110.0 liters (29 US gallons, 24 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.
What is Capsize Screening Formula (CSF)?
The capsize screening value for S2 9.2A is 1.93, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.
What is Theoretical Maximum Hull Speed?
The theoretical maximal speed of a displacement boat of this length is 6.7 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.
The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for S2 9.2A is about 160 kg/cm, alternatively 897 lbs/inch.
Meaning: if you load 160 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 897 lbs cargo on the boat it will sink 1 inch.

The ballast ratio for S2 9.2A is 41%.
What is Displacement Length Ratio?
The DL-ratio for S2 9.2A is 279 which categorizes this boat among 'medium weight cruisers'.
What is SA/D (Sail Area Displacement ratio)?
The SA/D for S2 9.2A with ISO 8666 reference sail is 16.4, with a 135% genua the SA/D is 19.6.
Maintenance
When buying anti-fouling bottom paint, it's nice to know how much to buy.
The surface of the wet bottom is about 26m2 (279 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.
