Cornish Shrimper 19 vs Mariner 19: the short version
- The Cornish Shrimper 19 and Mariner 19 are close in length (19.3 ft5.87 m vs 19.2 ft5.84 m ).
- The Cornish Shrimper 19 is heavier, displacing about 64% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Mariner 19 carries the more powerful rig (23.2 vs 17.6), favouring lighter-air performance.
- The Cornish Shrimper 19 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Cornish Shrimper 19 rates better for offshore work (2.15 vs 2.49).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
