1. A Sail Area/Displacement Ratio of just 14.7 suggests that the Tashiba 40 will need a stiff breeze to get her going. In light conditions, unless you've got plenty of time on your hands, motor-sailing may be the way to go.
2. A Ballast/Displacement Ratio of 35.5 means that unless the bulk of the ballast is concentrated in a bulb at the foot of her keel, the Tashiba 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 315, tells us the Tashiba 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 41.5 suggests that crew comfort of a Tashiba 40 in a seaway is similar to what you would associate with the motion of a heavy bluewater cruising boat. Pitching and rolling will be well damped - your cup of coffee on the salon table stands a reasonable chance of staying there in most conditions.
5. The Capsize Screening Formula (CSF) of 1.7 tells us that a Tashiba 40 would be a considerably safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
