1. Sail Area/Displacement Ratio: 16.8
2. Ballast/Displacement Ratio: 45.3
3. Displacement/Length Ratio: 266
4. Comfort Ratio: 35.5
5. Capsize Screening Formula: 1.8
1. A Sail Area/Displacement Ratio of 16.8 suggests that the Stephens 47 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 45.3 means that the Stephens 47 will stand up well to her canvas in a blow, helping her to power through the waves.
3. A Displacement/Length Ratio of 266, tells us the Stephens 47 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 35.5 suggests that crew comfort of a Stephens 47 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 a Stephens 47 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.

What is the Stephens 47 like to sail?
The Stephens 47 is a fast, comfortable, and seaworthy cruiser that can make swift passages of 200 nautical miles per day. The boat has a sharp entry that eliminates pounding in all but the heaviest weather, and an easy motion in a seaway due to its low-deadrise hull and weight distribution. The boat can turn around in about twice its length under power in forward, but tends to back into the wind in reverse at low speed.
