The hull is made of fibreglass while the deck is made of die cast fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.
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 0 cabins, 6-8 berths, a galley, 500.0 liter fresh water capacity and toilet facility.
Unknown keel type
The boat can enter even shallow marinas as the draft is just about 1.10 - 1.20 meter (3.61 - 3.91 ft) dependent on the load. See immersion rate below.
Neptunus 133 may be equipped with an inboard Volvo Penta engine at 306 hp (227 kW). Max speed is 25.0 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 fuel tank, which is made of stainless steel, has a capacity of 1260.0 liters (332 US gallons, 277 imperial gallons).
