Both the hull and the deck is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.
The interior is like many other boats made of mahogany. Mahogany belongs to the hardwood species, known for being water-repellent and resistant to decay. It has an attractive wood grain and holds wood polish and varnish well.
The boat is equipped with 4 cabins, 6 berths, a galley and 320.0 liter fresh water capacity.
The Contrast 400 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.
Fin keel
The Contrast 400 is equipped with a fin keel. The fin keel is the most common keel and provides splendid manoeuvrability. The downside is that it has less directional stability than a long keel.
The keel is made of lead. Compared with iron, lead has the advantage of being 44% heavier, which allows a smaller keel and hence less water resistance and higher speed.
The boat can only enter major marinas as the draft is about 2.05 - 2.15 meter (6.73 - 7.03 ft) dependent on the load. See immersion rate below.
The Contrast 400 has been equipped with different engine alternatives.
Alternative 1:
Contrast 400 may be equipped with an inboard Yanmar diesel engine at 43 hp (32 kW). Calculated max speed is about 6.7 knots
The transmission is a saildrive.
Alternative 2:
The boat may be equipped with an inboard Volvo Penta engine
The transmission is a saildrive.
The fuel tank has a capacity of 130.0 liters (34 US gallons, 28 imperial gallons).
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.
What is Capsize Screening Formula (CSF)?
The capsize screening value for Contrast 400 is 1.91, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.
What is Theoretical Maximum Hull Speed?
The theoretical maximal speed of a displacement boat of this length is 7.5 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 Contrast 400 is about 237 kg/cm, alternatively 1332 lbs/inch.
Meaning: if you load 237 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 1332 lbs cargo on the boat it will sink 1 inch.

When buying anti-fouling bottom paint, it's nice to know how much to buy.
The surface of the wet bottom is about 41m2 (441 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.
