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.
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, 8-10 berths, a galley, 750.0 liter fresh water capacity, toilet facility and 120.0 liter waste water capacity.
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.
The Neptunus 145 has been equipped with different engine alternatives.
