Review of Dufour 2800

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.

The hull is a sandwich construction which improves the indoor climate. Especially when the water is colder than the air in the cabin, then the double hull insulates against cold water and reduce the condense water in the cabin.

The interior is like many other boats made of mahogany. Mahogany belongs to the hardwood species, known for being water-repellent and resistant to decay. It has an attractive wood grain and holds wood polish and varnish well.
The boat is equipped with 5 berths, a galley, 130.0 liter fresh water capacity and toilet facility.

The Dufour 2800 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.

Keel of Dufour 2800.

The Dufour 2800 has been built with different keel alternatives.

CentreBoard

One option is a centreboard keel. A centreboard keel is a pivoting lifting keel, allowing to sail both coastal and inland waters.

The keel is made of iron. Many people prefer lead keel in favour of iron. The main argument is that lead is much heavier than iron and a lead keel can therefore be made smaller which again result in less wet surface, i.e. less drag. In fact iron is quite heavy, just 30% less heavy than lead, so the advantage of a lead keel is often overstated.

The boat can enter even shallow marinas as the draft is just about 0.85 - 0.95 meter (2.79 - 3.09 ft) dependent on the load. See immersion rate below.

Deep keel

Another option is a deep keel. A deep keel provide a better healing moment than a shallow keel.

This keel is also made of iron.

Dufour 2800 can enter most marinas as the draft is just about 1.50 - 1.60 meter (4.92 - 5.22 ft) dependent on the load. See immersion rate below.

Shallow keel

Another option is a shallow keel. A shallow keel allow to sail both coastal and inland waters.

This keel is also made of iron.

The boat can enter even shallow marinas as the draft is just about 1.20 - 1.30 meter (3.94 - 4.24 ft) dependent on the load. See immersion rate below.

The boat may be equipped with an inboard Volvo Penta MD5 diesel engine at 7 hp (5 kW). The speed is 6.0 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 40.0 liters (10 US gallons, 8 imperial gallons).

What is Capsize Screening Formula (CSF)?

The capsize screening value for Dufour 2800 is 2.07, indicating that this boat would not be accepted to participate in ocean races.

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 6.4 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Dufour 2800 is about 134 kg/cm, alternatively 753 lbs/inch.
Meaning: if you load 134 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 753 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Dufour 2800 is 20.2.

What is L/B (Length Beam Ratio)?

The l/b ratio for Dufour 2800 is 2.82.

What is a Ballast Ratio?

The ballast ratio for Dufour 2800 is 33%.

What is Displacement Length Ratio?

The DL-ratio for Dufour 2800 is 251 which categorizes this boat among 'light crusers & offshore racers'.

What is SA/D (Sail Area Displacement ratio)?

The SA/D for Dufour 2800 with ISO 8666 reference sail is 14.3, with a 135% genua the SA/D is 17.1.

What is Relative Speed Performance?

The Relative Speed Performance for Dufour 2800 is 42

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 23m² (247 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.
