1. Sail Area/Displacement Ratio: 19.1
2. Ballast/Displacement Ratio: 32.7
3. Displacement/Length Ratio: 165
4. Comfort Ratio: 31.7
5. Capsize Screening Formula: 1.9
1. A Sail Area/Displacement Ratio of 19.1 suggests that the Hanse 548 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 32.7 would usually mean that the Hanse 548 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 165, tells us the Hanse 548 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 31.7 suggests that crew comfort of a Hanse 548 in a seaway is similar to what you would associate with the motion of a moderate bluewater cruising boat - a predictable and acceptable motion for most seasoned sailors.
5. The Capsize Screening Formula (CSF) of 1.9 tells us that a Hanse 531 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
