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 980.0 liter fresh water capacity.
The Hanse 675 is equipped with a masthead rig. The advantage of a masthead rig is its simplicity and the fact that a given sail area - compared with a fractional rig - can be carried lower and thus with less heeling moment.
The Hanse 675 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 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 3.10 - 3.20 meter (10.17 - 10.47 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 675 can only enter major marinas as the draft is about 2.70 - 2.80 meter (8.86 - 9.16 ft) dependent on the load. See immersion rate below.
The boat may be equipped with an inboard Volvo Penta D3-150 diesel engine at 150 hp (111 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 1100.0 liters (290 US gallons, 241 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.
Hanse 675 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 10.6 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 675 is about 758 kg/cm, alternatively 4250 lbs/inch.
Meaning: if you load 758 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 4250 lbs cargo on the boat it will sink 1 inch.
Sailing statistics
This section is statistical comparison with similar boats of the same category. The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.
What is L/B (Length Beam Ratio)?
The l/b ratio for Hanse 675 is 3.47.
Sorry, we do not have sufficient statistical information available for this boat to provide a significant reliable analysis.
Maintenance
When buying anti-fouling bottom paint, it's nice to know how much to buy.
The surface of the wet bottom is about 130m2 (1399 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.
