1. Sail Area/Displacement Ratio: 16.3
2. Ballast/Displacement Ratio: 42.9
3. Displacement/Length Ratio: 237
4. Comfort Ratio: 35.9
5. Capsize Screening Formula: 1.7
1. A Sail Area/Displacement Ratio of 16.3 suggests that the Norseman 447 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 42.9 means that the Norseman 447 will stand up well to her canvas in a blow, helping her to power through the waves.
3. A Displacement/Length Ratio of 237, tells us the Norseman 447 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 35.9 suggests that crew comfort of a Norseman 447 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 Norseman 447 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
