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 boat is equipped with a galley.

The boat can sail close to the beach as the draft is just 0.16 - 0.26 meter (0.52 - 0.82 ft) dependent of the load. See immersion rate below.

Limbo 520 is typical equipped with an outboard engine.

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.

Immersion rate
The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Limbo 520 is about 73 kg/cm, alternative 413 lbs/inch.
Meaning: if you load 73 kg cargo on the boat then it will sink 1 cm. Alternative, if you load 413 lbs cargo on the boat it will sink 1 inch.

Sailing statistics

This section is statistical comparison with similar boats of the same category. The basis of the following statistical computations is our unique database with more than 22,000 boat types and 350,000 data points.

Slim Wide 58% 0 50 100
Compared with other similar motor boats it is more spacy than 58% of all other designs. It seems that the designer has chosen a slightly more spacy 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:
Equation for Danish definition of a powerboat
Danish definition of a powerboat
According to this definition this boat is not categorized as a Powerboat.
Though, if you install a motor of 30 kW (40 hp), then the boat will become a powerboat, and you will need a Danish 'powerboat driving license'

We always hunger for new photos. If you can contribute with photos for Limbo 520 it would be a great help.
