1. A Sail Area/Displacement Ratio of 17.9 suggests that the Rival 38 will, in the right conditions, approach her maximum hull speed readily and satisfy the sailing performance expectations of most cruising sailors.
2. In the absence of a published Ballast/Displacement Ratio for the Rival 38 we are unable to make any assessment of her stiffness under sail.
3. A Displacement/Length Ratio of 300, tells us the Rival 38 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 33.3 suggests that crew comfort of a Rival 38 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 1.7 tells us that a Rival 38 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
