1. Sail Area/Displacement Ratio: 17.0
2. Ballast/Displacement Ratio: 36.0
3. Displacement/Length Ratio: 206
4. Comfort Ratio: 27.4
5. Capsize Screening Formula: 1.9
1. A Sail Area/Displacement Ratio of 17.0 suggests that the Dufour Classic 45 will, in the right conditions, approach her maximum hull speed readily and satisfy the sailing performance expectations of most cruising sailors.
2. A Ballast/Displacement Ratio of 36.0 would usually mean that the Dufour Classic 45 would have a tendency to heel uncomfortably in a gust, and need to be reefed early to keep her sailing upright in a moderate breeze.
However, as she has much of her ballast concentrated in a bulb at the foot of her keel, she's likely to be considerably stiffer than her published Ballast/Displacement Ratio might suggest.
3. A Displacement/Length Ratio of 206 tells us the Dufour Classic 45 is a moderate displacement cruiser, which means she'll carry all your cruising gear without it having a dramatic effect on her performance. Most of today's sailboats intended for offshore cruising fall into this displacement category.
4. Ted Brewer's Comfort Ratio of 27.4 suggests that crew comfort of a Dufour Classic 45 in a seaway is similar to what you would associate with the motion of a coastal cruiser with moderate stability, which is not encouraging news for anyone prone to seasickness.
5. The Capsize Screening Formula (CSF) of 1.9 indicates that a Dufour Classic 45 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
In the Dufour range of sailboats, what is the difference between the 'Grand Large' range, the 'Classic' range, the 'Performance' range and the 'Exclusive' range?

Is the Dufour Classic 45 still in production and, if not, when did production end and how many of these sailboats were built?
No, the Dufour Classic 45 is not in production anymore. Production ended in 2001 after 13 years. The exact number of boats built is not known, but it is estimated to be around 200.
What is the difference between the standard (or owners) version and the charter version of the Dufour Classic 45?
The standard (or owners) version of the Dufour Classic 45 has three cabins and two heads, one of which is en-suite to the owner's cabin in the bow. The saloon has a U-shaped settee to port and a long settee to starboard, with a folding table in between. The galley is L-shaped and located to port, opposite the navigation station.
The charter version has four cabins and two heads, with two double cabins in the bow and two double cabins in the stern. The saloon has two U-shaped settees on both sides, with a fixed table in between. The galley is linear and located to port, next to the companionway.
What keel options are available for the Dufour Classic 45?
The Dufour Classic 45 has two keel options: a deep fin keel with a bulb or a shallow fin keel with a wing. The deep keel has a draft of 2.3 meters and a ballast of 3,946 kilograms. The shallow keel has a draft of 1.95 meters and a ballast of 4,100 kilograms.
