Interior
The boat is equipped with 7 berths.

Keel

The boat can only enter major marinas as the draft is about 1.80 - 1.90 meter (5.91 - 6.21 ft) dependent on the load. See immersion rate below.


Engine

Törn 120 is typically equipped with an inboard diesel engine at 55.0 hp (40 kW).

The transmission is a shaft drive. A shaft drive will in the long run require less maintenence than other types of drive e.g. a sail drive.


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 Törn 120 is 1.70, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.


Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Törn 120 is about 313 kg/cm, alternatively 1755 lbs/inch.
Meaning: if you load 313 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1755 lbs cargo on the boat it will sink 1 inch.

- Cruising Boats have ratios 10-15
- Cruiser-Racers have ratios 16-20
- Racers have ratios above 20
- High-Performance Racers have ratios above 24
