The C&C 34+ Sailboat
The C&C 34+, a cruiser/racer sailboat, was designed by Robert Ball and built in Canada by C&C (Cuthbertson & Cassian) Yachts.
The sailing performance of the C&C 34+ makes her a popular choice for cruising sailors wishing to compete in club races and regattas

Published Design Ratios for the C&C 34+
1. Sail Area/Displacement Ratio: 20.5
- 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: 43.5
- Under 40: less stiff, less powerful
- Over 40: stiffer, more powerful
3. Displacement/Length Ratio: 183
- Under 100: Ultralight
- 100 to 200: Light
- 200 to 275: Moderate
- 275 to 350: Heavy
- Over 350: Ultraheavy
4. Comfort Ratio: 22.0
- 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: 2.0
- 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 C&C 34+
1. A Sail Area/Displacement Ratio of 20.5 suggests that, in the right hands, the C&C 34+ will have enough performance to leave most other sailboats of similar waterline length in her wake.
2. A Ballast/Displacement Ratio of 43.5 means that the C&C 34+ will stand up well to her canvas in a blow, helping her to power through the waves.
3. A Displacement/Length Ratio of 183, tells us the C&C 34+ is clearly a light displacement sailboat. If she's loaded with too much heavy cruising gear her performance will suffer dramatically.
4. Ted Brewer's Comfort Ratio of 22.0 suggests that crew comfort of a C&C 34+ 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 of 2.0 tells us that a C&C 34+ would not be a good choice of sailboat for ocean passage-making, owing to the increased risk of capsize in strong winds and heavy seas when compared to a sailboat with a CSF of less than 2.0.
