1. A Sail Area/Displacement Ratio of 16.8 suggests that the Bowman 40 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 any published Ballast/Displacement for the Bowman 40 we are unable to make any assessment of this element of her stiffness under sail, but this review by Yachting Monthly says "she’s stiff and easily capable of standing up to her canvas".
3. A Displacement/Length Ratio of 259, tells us the Bowman 40 is a moderate displacement cruiser, which means she'll carry all your cruising gear without it having a dramatic effect on her performance. Most of today's sailboats intended for offshore cruising fall into this displacement category.
4. Ted Brewer's Comfort Ratio of 29.3 suggests that crew comfort of a Bowman 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 1.9 indicates that a Bowman 40 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
