Review of Tresfjord Lux 26

The hull 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 interior is like many other boats made of mahogany.
The boat is equipped with 2 cabins, 5 berths, a galley and toilet facility.

The Tresfjord Lux 26 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 1.00 - 1.10 meter (3.28 - 3.58 ft) dependent on the load. See immersion rate below.

Tresfjord Lux 26 is typically equipped with an inboard Volvo Penta engine at 75.0 hp (55 kW).

The fuel tank has a capacity of 110.0 liters (29 US gallons, 24 imperial gallons).

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 6.7 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 Tresfjord Lux 26 is about 132 kg/cm, alternatively 741 lbs/inch.
Meaning: if you load 132 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 741 lbs cargo on the boat it will sink 1 inch.

What is L/B (Length Beam Ratio)?

The l/b ratio for Tresfjord Lux 26 is 3.08.

Compared with other similar motor boats it is slimmer than 69% 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 67 kW (89 hp), then the boat will become a powerboat, and you will need a Danish 'powerboat driving license'
