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 of Tur 84 anno 1978.
The interior is like most other boats made of teak.
The boat is equipped with 5 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.

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.

Tur 84 is typically equipped with an inboard Yanmar YSE8 diesel engine at 8.0 hp (5 kW), which gives a max speed about 4.4 knots.
The fuel tank has a capacity of 22 liters (5 US gallons, 4 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 Tur 84 is 1.93, 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 Tur 84 is about 125 kg/cm, alternatively 702 lbs/inch.
Meaning: if you load 125 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 702 lbs cargo on the boat it will sink 1 inch.
