SB20 vs Vastbris: the short version
- The SB20 and Vastbris are close in length (20.3 ft6.20 m vs 20.2 ft6.15 m ).
- The Vastbris is heavier, displacing about 134% 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 14.8), favouring lighter-air performance.
- By the capsize screening formula the Vastbris rates better for offshore work (1.83 vs 2.40).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
