1. Sail Area/Displacement Ratio: 16.2
2. Ballast/Displacement Ratio: 30.0
3. Displacement/Length Ratio: 182
4. Comfort Ratio: 24.8
5. Capsize Screening Formula: 2.0
1. A Sail Area/Displacement Ratio of 16.2 suggests that the Jeanneau Sun Odyssey 40.3 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 30.0 would usually mean that the Jeanneau Sun Odyssey 40.3 would have a tendency to heel excessively 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 the keel, she's likely to be considerably stiffer than her published Ballast/Displacement Ratio might suggest.
3. A Displacement/Length Ratio of 182, tells us the Jeanneau Sun Odyssey 40.3 is clearly a light displacement sailboat. If she's loaded with too much heavy cruising gear her performance will suffer dramatically.
4. Ted Brewer's Comfort Ratio of 24.8 suggests that crew comfort of a Jeanneau Sun Odyssey 40.3 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 2.0 indicates that a Jeanneau Sun Odyssey 40.3 would not be the wisest choice of sailboat for ocean passage-making owing to the lower resistance to capsize in strong winds and heavy seas that is associated with sailboats with a CSF of 2.0 and above.

'Endeavour' is a very special Tartan 34C, as you will see from the cutter rig modification, Ratcliffe wind vane auxiliary rudder self-steering, SSB radio, radar, and more.

The broad beam, large cockpit and spacious salon of the Dudley Dix Hout Bay 40 make for a very comfortable sailboat to live aboard and sail.
