Review of Hanse 548

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 a galley and 770.0 liter fresh water capacity.

The Hanse 548 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 548 has been built with different keel alternatives.

Shallow keel

One option is a shallow keel. A shallow keel allow to sail both coastal and inland waters.

The boat can only enter major marinas as the draft is about 2.20 - 2.30 meter (7.22 - 7.52 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 548 can only enter major marinas as the draft is about 2.55 - 2.65 meter (8.37 - 8.67 ft) dependent on the load. See immersion rate below.

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 boat can only enter major marinas as the draft is about 2.80 - 2.90 meter (9.19 - 9.49 ft) dependent on the load. See immersion rate below.

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

What is Capsize Screening Formula (CSF)?

The capsize screening value for Hanse 548 is 1.91, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

Hanse 548 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 548 is about 504 kg/cm, alternatively 2823 lbs/inch.
Meaning: if you load 504 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 2823 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Hanse 548 is 30.7.

What is L/B (Length Beam Ratio)?

The l/b ratio for Hanse 548 is 3.12.

What is Displacement Length Ratio?

The DL-ratio for Hanse 548 is 160 which categorizes this boat among 'light racers'.

SA/D (Sail Area Displacement ratio)
Indicates how fast the boat is in light wind:
- Cruising Boats have ratios 10-15
- Cruiser-Racers have ratios 16-20
- Racers have ratios above 20
- High-Performance Racers have ratios above 24
Sail-area/displacement ratio (SA/D ratio): 19.71

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 81m² (871 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.

If you need to renew parts of your running rig and is not quite sure of the dimensions, you may find the estimates computed below useful.
