Hull

Both the hull and the deck is made of hand laid fibreglass. Generally, a hull made of hand laid 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 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, 6-7 berths, a galley, 132.0 liter fresh water capacity and toilet facility.


Keel

Unknown keel type

The boat can enter even shallow marinas as the draft is just about 0.81 - 0.91 meter (2.66 - 2.96 ft) dependent on the load. See immersion rate below.

Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Sea Ray 280 Sundancer is about 182 kg/cm, alternatively 1024 lbs/inch.
Meaning: if you load 182 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1024 lbs cargo on the boat it will sink 1 inch.
