12 Square meter Sharpie vs Halman 20: the short version
- The 12 Square meter Sharpie and Halman 20 are close in length (19.6 ft5.99 m vs 19.7 ft6.00 m ).
- The Halman 20 is heavier, displacing about 393% more, which usually means a steadier but slower-to-accelerate hull.
- By the capsize screening formula the Halman 20 rates better for offshore work (2.28 vs 2.35).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
