1. A Sail Area/Displacement Ratio of 16.9 suggests that the Bayfield 40 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 35.1 means that unless the bulk of the ballast is concentrated in a bulb at the foot of her keel, the Bayfield 40 will have a tendency to heel excessively in a gust, and she'll need to be reefed early to keep her sailing upright in a moderate breeze.
3. A Displacement/Length Ratio of 291, tells us the Bayfield 40 is clearly a heavy displacement cruising boat. You can load her down with all your cruising gear and equipment and it will hardly affect her waterline. Not an ideal choice for coastal sailing, but she'll come into her own on an offshore passage in testing conditions.
4. Ted Brewer's Comfort Ratio of 30.7 suggests that crew comfort of a Bayfield 40 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 1.8 tells us that a Bayfield 40 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
