The hull is made of hand laid fibreglass. Generally, a hull made of hand laid fibreglass requires only a minimum of maintenance during the sailing season.
The boat is equipped with a galley and 300.0 liter fresh water capacity.
The Hanse 370 is equipped with a fractional rig. A fractional rig has smaller headsails which make tacking easier, which is an advantage for cruisers and racers, of course. The downside is that having the wind from behind often requires a gennaker or a spinnaker for optimal speed.
The Hanse 370 has been built with different keel alternatives.
Unknown keel type
The boat can enter most marinas as the draft is just about 1.60 - 1.70 meter (5.25 - 5.55 ft) dependent on the load. See immersion rate below.
Fin keel
The Hanse 370 is equipped with a fin keel. The fin keel is the most common keel and provides splendid manoeuvrability. The downside is that it has less directional stability than a long keel.
Hanse 370 can only enter major marinas as the draft is about 1.95 - 2.05 meter (6.40 - 6.70 ft) dependent on the load. See immersion rate below.
The boat may be equipped with an inboard Yanmar 3YM20 diesel engine at 21 hp (15 kW). Calculated max speed is about 5.1 knots
The transmission is a saildrive.
The fuel tank has a capacity of 140.0 liters (36 US gallons, 30 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.
What is Capsize Screening Formula (CSF)?
The capsize screening value for Hanse 370 is 2.00, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.
Hanse 370 holds a CE certification:
The boat is by European Union certified as Class A. OCEAN:What is Theoretical Maximum Hull Speed?
The theoretical maximal speed of a displacement boat of this length is 7.7 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 Hanse 370 is about 252 kg/cm, alternatively 1413 lbs/inch.
Meaning: if you load 252 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 1413 lbs cargo on the boat it will sink 1 inch.

Maintenance
When buying anti-fouling bottom paint, it's nice to know how much to buy.
The surface of the wet bottom is about 40m2 (430 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.
