Hull

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.

Interior

The interior is like most other boats made of teak.
The boat is equipped with 2 cabins, 7 berths, a galley, toilet facility and 80.0 liter waste water capacity.

Keel

The boat can enter even shallow marinas as the draft is just about 0.90 - 1.00 meter (2.95 - 3.25 ft) dependent on the load. See immersion rate below.

Engine

Neptim 8000 is typically equipped with an inboard Volvo Penta TMD 40 diesel engine.

The fuel tank has a capacity of 400.0 liters (105 US gallons, 87 imperial gallons).

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 Neptim 8000 is about 172 kg/cm, alternatively 965 lbs/inch.
Meaning: if you load 172 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 965 lbs cargo on the boat it will sink 1 inch.

L/B (Length Beam Ratio)

What is L/B (Length Beam Ratio)?
