1. Sail Area/Displacement Ratio: 17.2
2. Ballast/Displacement Ratio: 33.6
3. Displacement/Length Ratio: 129
4. Comfort Ratio: 24.6
5. Capsize Screening Formula: 1.9
1. A Sail Area/Displacement Ratio of 17.2 suggests that the Beneteau Oceanis 473 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 33.6 would usually mean that the Beneteau Oceanis 473 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 129, tells us the Beneteau Oceanis 473 is clearly a light displacement sailboat. If she's loaded with too much heavy cruising gear her performance will suffer to a degree.
4. Ted Brewer's Comfort Ratio of 24.6 suggests that crew comfort of a Beneteau Oceanis 473 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 tells us that a Beneteau Oceanis 473 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
