Greenwich 24 vs Seidelmann 245: the short version
- The Greenwich 24 and Seidelmann 245 are close in length (24.3 ft7.39 m vs 24.2 ft7.37 m ).
- The Greenwich 24 is heavier, displacing about 28% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Seidelmann 245 carries the more powerful rig (20.5 vs 16.7), favouring lighter-air performance.
- The Greenwich 24 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Greenwich 24 rates better for offshore work (1.85 vs 2.22).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
