Hull

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. And outside the sailing season, just bottom cleaning and perhaps anti-fouling painting once a year - a few hours of work, that's all.

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 2 berths, a galley, 45.0 liter fresh water capacity and toilet facility.

Keel

Unknown keel type

The boat can sail close to the beach as the draft is just 0.35 - 0.45 meter (1.15 - 1.45 ft) dependent of the load. See immersion rate below.

Engine

Coronet 22 Daycruiser may be equipped with dual inboard Volvo Penta engines at 290 hp (216 kW). Max speed is 35.0 knots.

The fuel tank, which is made of galvanized iron, has a capacity of 220.0 liters (58 US gallons, 48 imperial gallons).
