The Finngulf 36 is equipped with a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with 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.
The boat can only enter major marinas as the draft is about 1.98 - 2.08 meter (6.50 - 6.80 ft) dependent on the load. See immersion rate below.
The boat is typically equipped with an inboard Volvo Penta 2002 diesel engine at 18.0 hp (13 kW), which gives a max speed about 4.6 knots.
The transmission is a saildrive.
The fuel tank which is made of stainless steel has a capacity of 75.0 liters (19 US gallons, 16 imperial gallons).
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 Finngulf 36 is 1.84, 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 7.1 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 Finngulf 36 is about 190 kg/cm, alternatively 1067 lbs/inch.
Meaning: if you load 190 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 1067 lbs cargo on the boat it will sink 1 inch.

When buying anti-fouling bottom paint, it's nice to know how much to buy.
The surface of the wet bottom is about 34m2 (365 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.
