Santana 20 vs SB20: the short version
- The Santana 20 and SB20 are close in length (20.3 ft6.17 m vs 20.3 ft6.20 m ).
- The SB20 is heavier, displacing about 12% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the SB20 carries the more powerful rig (35.7 vs 24.4), favouring lighter-air performance.
- By the capsize screening formula the SB20 rates better for offshore work (2.40 vs 2.90).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
