1. A Sail Area/Displacement Ratio of 18.1 suggests that the Island Packet 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 43.9 means that the Island Packet 40 will stand up well to her canvas in a blow, helping her to power through the waves.
3. A Displacement/Length Ratio of 259, tells us the Island Packet 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 32.6 suggests that crew comfort of an Island Packet 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 an Island Packet 40 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
