Hull

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.


Interior

The boat is equipped with 4 berths, a galley and toilet facility.


Keel

Unknown keel type

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.


Engine

Nimbus 4000 may be equipped with dual inboard Volvo Penta TAMD 41 diesel engines at 400 hp (298 kW).

The transmission is a shaft drive. A shaft drive will in the long run require less maintenance than other types of drive e.g. a sail drive.


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 Nimbus 4000 is about 241 kg/cm, alternatively 1350 lbs/inch.
Meaning: if you load 241 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1350 lbs cargo on the boat it will sink 1 inch.
