Review of Malö 42

The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.
The hull is a double hull which improves the indoor climate. Especially when the water is colder than the air in the cabin, then the double hull insulates against cold water and reduce the condense water in the cabin.

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, 750.0 liter fresh water capacity, toilet facility and 70.0 liter waste water capacity.

The Malö 42 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.

Fin keel

The Malö 42 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 boat can only enter major marinas as the draft is about 1.95 - 2.05 meter (6.40 - 6.70 ft) dependent on the load. See immersion rate below.

Malö 42 may be equipped with an inboard Yanmar diesel engine at 97 hp (72 kW). Calculated max speed is about 7.9 knots

The fuel tank has a capacity of 285.0 liters (75 US gallons, 62 imperial gallons).

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 47m² (505 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.
