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.
Note: the boat has also been sold to be self-made/-interiored, which means that the quality of each boat may vary.
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.
An outboard motor is often used on this boat.
In that case the boat will typically require a power of 3 - 4 hp,
alternatively 65 - 78 lbs thrust if you prefer an electrical motor. Electric outboards are
becoming popular for sailboat owners who want clean instant power with less noise and no exhaust fumes.
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 Junker 22 is 1.76, 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 5.7 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 Junker 22 is about 72 kg/cm, alternatively 408 lbs/inch.
Meaning: if you load 72 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 408 lbs cargo on the boat it will sink 1 inch.
