The boat is equipped with 5 berths, a galley and toilet facility.
The boat has more than one rig.
One option is 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.
Another option is 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.
Unknown keel type
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.
Möre 30 can enter most marinas as the draft is just about 1.60 - 1.70 meter (5.25 - 5.55 ft) dependent on the load. See immersion rate below.
The Möre 30 has been equipped with different engine alternatives.
Alternative 1:
The boat may be equipped with an inboard Yanmar diesel engine at 12 hp (8 kW). Calculated max speed is about 4.6 knots
Alternative 2:
The boat may be equipped with an inboard Yanmar diesel engine at 18 hp (13 kW). Calculated max speed is about 5.6 knots
Alternative 3:
Möre 30 may be equipped with an inboard Arona diesel engine at 8 hp (5 kW). Calculated max speed is about 3.8 knots
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.
What is Capsize Screening Formula (CSF)?
The capsize screening value for Möre 30 is 2.05, indicating that this boat would not 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 6.4 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 Möre 30 is about 137 kg/cm, alternatively 771 lbs/inch.
Meaning: if you load 137 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 771 lbs cargo on the boat it will sink 1 inch.

Maintenance
When buying anti-fouling bottom paint, it's nice to know how much to buy.
The surface of the wet bottom is about 24m2 (258 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.
