Hull

The hull is made of hand laid fibreglass while the deck is made of fibreglass. Generally, a hull made of hand laid fibreglass requires only a minimum of maintenance during the sailing season.
The hull is a double hull which improves the indoor climate. Especially when the water is colder than the air in the cabin, then the double hull insulates against cold water and reduce the condense water in the cabin.
The deck is a double deck which improves the indoor climate.


Interior

The interior is like most other boats made of teak. Teak has the advantage of being naturally very oily and therefore water-repellent, which is suitable on boats.
The boat is equipped with 3 cabins, 6 berths, a galley, 270.0 liter fresh water capacity and toilet facility.


Keel

Unknown keel type

The boat can enter even shallow marinas as the draft is just about 0.80 - 0.90 meter (2.62 - 2.92 ft) dependent on the load. See immersion rate below.


Engine

The Princess 330 has been equipped with different engine alternatives.

Alternative 1:

Princess 330 may be equipped with dual inboard Volvo Penta TMD 41 diesel engines at 150 hp (111 kW). Max speed is 20.0 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 2:

The boat may be equipped with dual inboard Volvo Penta TAMD 41 diesel engines at 200 hp (149 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 3:

The boat may be equipped with dual inboard Volvo Penta TAMD 41 diesel engines at 200 hp (149 kW).

The transmission is a Z-drive aka sterndrive.

Alternative 4:

Princess 330 may be equipped with dual inboard Volvo Penta AQ 151/290 gasoline engines at 146 hp (108 kW).

Alternative 5:

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 Princess 330 is about 263 kg/cm, alternatively 1477 lbs/inch.
Meaning: if you load 263 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1477 lbs cargo on the boat it will sink 1 inch.
