Review of Dufour 29

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 Dufour 29 has been built with different keel alternatives.

Deep keel

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

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 most marinas as the draft is just about 1.64 - 1.74 meter (5.38 - 5.68 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 1.35 - 1.45 meter (4.43 - 4.73 ft) dependent on the load. See immersion rate below.

Dufour 29 is typically equipped with an inboard Volvo Penta MD6A diesel engine at 10 hp (7 kW). Calculated max speed is about 4.4 knots

What is Capsize Screening Formula (CSF)?

The capsize screening value for Dufour 29 is 1.95, indicating that this boat could - if evaluated by this formula alone - 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 6.7 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 29 is about 147 kg/cm, alternatively 826 lbs/inch.
Meaning: if you load 147 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 826 lbs cargo on the boat it will sink 1 inch.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Dufour 29 is 21.3.

What is L/B (Length Beam Ratio)?

The l/b ratio for Dufour 29 is 3.11.

What is a Ballast Ratio?

The ballast ratio for Dufour 29 is 36%.

What is Displacement Length Ratio?

The DL-ratio for Dufour 29 is 205 which categorizes this boat among 'light crusers & offshore racers'.

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

The SA/D for Dufour 29 with ISO 8666 reference sail is 15.5, with a 135% genua the SA/D is 18.6.

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 26m² (279 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.
