Published Design Ratios for the Hunter Channel 323
1. Sail Area/Displacement Ratio: 15.7
- Less than 16 would be considered under-powered;
- 16 to 20 would indicate reasonably good performance;
- Over 20 suggests relatively high performance.
2. Ballast/Displacement Ratio: 45.0
- Under 40: less stiff, less powerful
- Over 40: stiffer, more powerful
3. Displacement/Length Ratio: 207
- Under 100: Ultralight
- 100 to 200: Light
- 200 to 275: Moderate
- 275 to 350: Heavy
- Over 350: Ultraheavy
4. Comfort Ratio: 22.7
- Under 20 indicates a lightweight racing boat
- 20 to 30 indicates a coastal cruiser
- 30 to 40 indicates a moderate offshore cruising boat
- 40 to 50 indicates a heavy offshore boat
- Over 50 indicates an extremely heavy offshore boat
5. Capsize Screening Formula: 1.9
- Under 2.0 (the lower the better): Better suited for ocean passages
- Over 2.0: Less suited for ocean passages

Summary Analysis of the Design Ratios for the Hunter Channel 323
1. A Sail Area/Displacement Ratio of just 15.7 suggests that the Hunter Channel 323 is a tad underpowered and 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 45.0 means that the Hunter Channel 323 will stand up well to her canvas in a blow, helping her to power through the waves.
3. A Displacement/Length Ratio of 207, tells us the Hunter Channel 323 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 22.7 suggests that crew comfort of a Hunter Channel 323 in a seaway is similar to what you would associate with the motion of a coastal cruiser with moderate stability, which is not encouraging news for anyone prone to seasickness.
5. The Capsize Screening Formula (CSF) of 1.9 indicates that a Hunter Channel 323 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.

Medium sized cruising yachts like these are often the sailboat of choice for short-handed crews, and if properly equipped and maintained, will take long offshore voyages in their stride.
