Review of Molich 12 M

The hull is made of fibreglass while the deck is made of wood. 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 3 cabins, 8 berths, a galley, 180.0 liter fresh water capacity and toilet facility.

The Molich 12 M 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.

Keel of Molich 12 M anno 1987.

Fin keel

The Molich 12 M is equipped with a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a full 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 2.00 - 2.10 meter (6.56 - 6.86 ft) dependent on the load. See immersion rate below.

Molich 12 M may be equipped with an inboard Bukh diesel engine at 40 hp (29 kW). The speed is 9.0 knots.

The transmission is a saildrive.

The fuel tank, which is made of stainless steel, has a capacity of 100.0 liters (26 US gallons, 21 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 48m² (516 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.
