Review of Hanse 575

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 810.0 liter fresh water capacity.

The Hanse 575 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 575 has been built with different keel alternatives.

Torpedo keel

But be aware that even though a T keel is very good for speed racing, a fishing nets and the like in the water can easily make you into a troublesome situation.

The keel is made of iron. Many people prefer lead keel in favour of iron. The main argument is that lead is much heavier than iron and a lead keel can therefore be made smaller which again result in less wet surface, i.e. less drag. In fact iron is quite heavy, just 30% less heavy than lead, so the advantage of a lead keel is often overstated.

The boat can only enter major marinas as the draft is about 2.85 - 2.95 meter (9.35 - 9.65 ft) dependent on the load. See immersion rate below.

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.

This keel is also made of iron.

Hanse 575 can only enter major marinas as the draft is about 2.25 - 2.35 meter (7.38 - 7.68 ft) dependent on the load. See immersion rate below.

The boat may be equipped with an inboard Volvo Penta D3-110 diesel engine at 107 hp (79 kW).

The transmission is a shaft drive. A shaft drive will in the long run require less maintenance than other types of drive e.g. a sail drive.

The fuel tank has a capacity of 520.0 liters (137 US gallons, 114 imperial gallons).

Hanse 575 holds a CE certification:

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 9.4 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 575 is about 527 kg/cm, alternatively 2955 lbs/inch.
Meaning: if you load 527 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 2955 lbs cargo on the boat it will sink 1 inch.

What is L/B (Length Beam Ratio)?

The l/b ratio for Hanse 575 is 3.21.

What is a Ballast Ratio?

The ballast ratio for Hanse 575 is 30%.

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 91m² (979 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.
