Published Design Ratios for the Vancouver 27
1. Sail Area/Displacement Ratio: 14.2
- 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: 38.7
- Under 40: less stiff, less powerful
- Over 40: stiffer, more powerful
3. Displacement/Length Ratio: 332
- Under 100: Ultralight
- 100 to 200: Light
- 200 to 275: Moderate
- 275 to 350: Heavy
- Over 350: Ultraheavy
4. Comfort Ratio: 33.2
- 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: 1.7
- 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 Vancouver 27
1. A Sail Area/Displacement Ratio of just 14.2 suggests that she'll 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 38.7 means that unless the bulk of the ballast is concentrated in a bulb at the foot of her keel, she'll have a tendency to heel excessively in a gust, and she'll need to be reefed early to keep her sailing upright in a moderate breeze.
3. A Displacement/Length Ratio of 332, tells us she's clearly a heavy displacement cruising boat. You can load her down with all your cruising gear and equipment and it will hardly affect her waterline. Not an ideal choice for coastal sailing, but she'll come into her own on an offshore passage in testing conditions.
4. Ted Brewer's Comfort Ratio of 33.2 suggests that crew comfort 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. Her Capsize Screening Formula (CSF) of 1.7 tells us that she would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
