The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.
The boat is equipped with 450.0 liter fresh water capacity.
The Hanse 458 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 458 has been built with different keel alternatives.
L-shape fin keel
One option is a L keel. An L-shape keel is a bulb keel with the shape as an L. This keel is less exposed to seaweed, fishing nets and lines.
The boat can only enter major marinas as the draft is about 2.23 - 2.33 meter (7.32 - 7.62 ft) dependent on the load. See immersion rate below.
L-shape fin keel
Another option is a L keel. An L-shape keel is a bulb keel with the shape as an L. This keel is less exposed to seaweed, fishing nets and lines.
Hanse 458 can only enter major marinas as the draft is about 1.82 - 1.92 meter (5.97 - 6.27 ft) dependent on the load. See immersion rate below.
The Hanse 458 has been equipped with different engine alternatives.
Alternative 1:
The boat may be equipped with an inboard diesel engine at 57 hp (42 kW).
The transmission is a saildrive.
Alternative 2:

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.
Hanse 458 holds a CE certification:
If less than 10 in on board 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 8.5 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 458 is about 358 kg/cm, alternatively 2004 lbs/inch.
Meaning: if you load 358 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 2004 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 60m2 (645 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.
