The hull 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.
The boat is equipped with 5 berths, a galley, 57.0 liter fresh water capacity and toilet facility.
The Griffon 26 is equipped with a masthead rig. The advantage of a masthead rig is its simplicity and the fact that a given sail area - compared with a fractional rig - can be carried lower and thus with less heeling moment.
Bilge keel
The Griffon 26 is equipped with a bilge keel. A bilge keel is a double keel, which allows the boat to be beached. Bilge keels are the most popular keel for tidal waters.
The boat can enter even shallow marinas as the draft is just about 0.99 - 1.09 meter (3.25 - 3.55 ft) dependent on the load. See immersion rate below.
Griffon 26 may be equipped with an inboard Volvo Penta MD7A diesel engine
The fuel tank has a capacity of 38.0 liters (10 US gallons, 8 imperial gallons).

Maintenance
When buying anti-fouling bottom paint, it's nice to know how much to buy.
The surface of the wet bottom is about 19m2 (204 ft2).
Based on this, your favourite maritime shop can tell you the quantity you need.
Note: If you use a paint roller you will need more paint than if you use a paintbrush.
