Review of Nimbus 320 Coupé

Both the hull and the deck is made of fibreglass. 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 shape is deep V. Generally, a deep V hull gives a more comfortable cruise because it helps the boat cut through waves while minimizing impacts, help the boat bank into turns, and throw less spray. However, a deep V hull reduces stability and requires more power.

The boat is equipped with 2 cabins, 4 berths, a galley, 180 liters (47 US gallons, 39 imperial gallons) fresh water capacity and toilet facility.

The fuel tank has a capacity of 340 liters (89 US gallons, 74 imperial gallons).

The Nimbus 320 Coupé has been equipped with different engine alternatives.

Alternative 1:

The boat may be equipped with an inboard Yanmar 4LHA-Stp diesel engine at 240 hp (178 kW). Max speed is 21.0 knots.

Alternative 2:

Nimbus 320 Coupé may be equipped with an inboard Yanmar 4LH-STE diesel engine at 230 hp (171 kW). Max speed is 22.0 knots.

Alternative 3:

The boat may be equipped with an inboard Yanmar 4JH3-DTE diesel engine at 125 hp (93 kW).

Alternative 4:

The boat may be equipped with an inboard Volvo Penta D4-210 diesel engine at 210 hp (156 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.

Alternative 5:

Nimbus 320 Coupé may be equipped with an inboard Volvo Penta D4 diesel engine at 260 hp (193 kW). Cruise speed is 22.0 knots. Max speed is 26.0 knots.

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.

Alternative 6:

The boat may be equipped with an inboard Volvo Penta D4 diesel engine at 225 hp (167 kW). Cruise speed is 7.0 knots. Max speed is 23.0 knots.

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.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Nimbus 320 Coupé is about 210 kg/cm, alternatively 1176 lbs/inch.
Meaning: if you load 210 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1176 lbs cargo on the boat it will sink 1 inch.

What is L/B (Length Beam Ratio)?

The l/b ratio for Nimbus 320 Coupé is 3.06.

Compared with other similar motor boats it is more spacy than 50% of all other designs. It seems that the designer has chosen an average 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 categorized as a Powerboat.

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 30m² (322 ft²).
Based on this, your favourite maritime shop can tell you the quantity you need.

Note: If you use a paint roller you will need more paint than if you use a paintbrush.
