Review of Tur 84

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.

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).
