Seidelmann 245 vs Seidelmann 37: the short version
- The Seidelmann 37 is the larger boat at 36.8 ft11.23 m LOA versus 24.2 ft7.37 m for the Seidelmann 245.
- The Seidelmann 37 is heavier, displacing about 300% 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 19.6), favouring lighter-air performance.
- The Seidelmann 37 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Seidelmann 37 rates better for offshore work (2.10 vs 2.22).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
