Review of LM 29

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. And outside the sailing season, just bottom cleaning and perhaps anti-fouling painting once a year - a few hours of work, that's all.
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 boat is equipped with 2 berths and a galley.

The LM 29 is equipped with a long keel. A long keel provide a better directional stability than a similar boat with a fin keel; on the other hand, better directional stability means also that the boat is more difficult to handle in a harbour with less space.

The boat can enter even shallow marinas as the draft is just about 1.15 - 1.25 meter (3.77 - 4.07 ft) dependent on the load. See immersion rate below.

LM 29 is typically equipped with an inboard Ford diesel engine at 80.0 hp (59 kW).

The transmission is a shaft drive.

The fuel tank has a capacity of 70.0 liters (18 US gallons, 15 imperial gallons).

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 6.6 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 LM 29 is about 145 kg/cm, alternatively 816 lbs/inch.
Meaning: if you load 145 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 816 lbs cargo on the boat it will sink 1 inch.

What is L/B (Length Beam Ratio)?

The l/b ratio for LM 29 is 3.02.

Compared with other similar motor boats it is slimmer than 54% of all other designs. It seems that the designer has chosen a slightly more speedy hull design.

In Denmark, you are required to have achieved a 'powerboat driving license' in order to sail a powerboat.
In this context a boat is considered a powerboat if:

According to this definition this boat is not categorized as a Powerboat.
Though, if you install a motor of 79 kW (106 hp), then the boat will become a powerboat, and you will need a Danish 'powerboat driving license'
