Review of Hanse 458

The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.

The boat 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 genaker or a spinnaker for optimal speed.

The Hanse 458 has been built with more than one type of keel.

One option is 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.

Another option is a L keel. The keel is an L-shape and therefore 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.

The boat is typically equipped with an inboard diesel engine at 57.0 hp (42 kW).

The transmission is a saildrive.

The fuel tank has a capacity of 210.0 liters (55 US gallons, 46 imperial gallons).

Hanse 458 holds one 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.

What is L/B (Length Beam Ratio)?

The l/b ratio for Hanse 458 is 3.09.

Compared with other similar sailboats it is more spacy than 82% of all other designs. It seems that the designer has chosen a significantly more spacy hull design.

What is a Ballast Ratio?

The ballast ratio for Hanse 458 is 29%.

This ballast ratio shows a righting moment that is higher than 14% of all similar sailboat designs. A righting moment (ability to resist heeling) significantly below average.

The Hanse 458 has more rig than 85% of all similar sailboats, which indicates that the boat is significantly overrigged.

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.
