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 boat is equipped with 2-4 berths, a galley and 230.0 liter fresh water capacity.
The Hanse 315 (2015) 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 315 (2015) has been built with different keel alternatives.
Unknown keel type
The boat can only enter major marinas as the draft is about 1.85 - 1.95 meter (6.07 - 6.37 ft) dependent on the load. See immersion rate below.
Unknown keel type
Hanse 315 (2015) can enter even shallow marinas as the draft is just about 1.37 - 1.47 meter (4.49 - 4.79 ft) dependent on the load. See immersion rate below.
The boat may be equipped with an inboard engine at 11 hp (8 kW). Calculated max speed is about 4.1 knots
The transmission is a saildrive.
The fuel tank has a capacity of 100.0 liters (26 US gallons, 21 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 315 (2015) is 2.02, indicating that this boat would not be accepted to participate in ocean races.
Hanse 315 (2015) 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 7.2 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 315 (2015) is about 195 kg/cm, alternatively 1093 lbs/inch.
Meaning: if you load 195 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 1093 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 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.
