Published Design Ratios for the Saga 43
1. Sail Area/Displacement Ratio: 20.9
- 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: 39.3
- Under 40: less stiff, less powerful
- Over 40: stiffer, more powerful
3. Displacement/Length Ratio: 150
- Under 100: Ultralight
- 100 to 200: Light
- 200 to 275: Moderate
- 275 to 350: Heavy
- Over 350: Ultraheavy
4. Comfort Ratio: 27.9
- 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: 1.8
- 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 Saga 43
1. A Sail Area/Displacement Ratio of 20.9 suggests that, in the right hands, the Saga 43 will have enough performance to leave most other sailboats of similar waterline length well astern.
2. A Ballast/Displacement Ratio of 39.3 would usually mean that the xxxxx would have a tendency to heel excessively in a gust, and need to be reefed early to keep her sailing upright in a moderate breeze.
However, as she carries much of her ballast concentrated in a bulb at the foot of the keel, she's likely to be considerably stiffer than her published Ballast/Displacement Ratio might suggest.
3. A Displacement/Length Ratio of 150, tells us the Saga 43 is clearly a light displacement sailboat. If she's loaded with too much heavy cruising gear her performance will suffer to a degree.
4. Ted Brewer's Comfort Ratio of 27.9 suggests that crew comfort of a Saga 43 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 1.8 tells us that a Saga 43 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.

'Endeavour' is a very special Tartan 34C, as you will see from the cutter rig modification, Ratcliffe wind vane auxiliary rudder self-steering, SSB radio, radar, and more.
