Grampian 28 vs TES 28 Magnam: the short version
- The Grampian 28 and TES 28 Magnam are close in length (28.0 ft8.53 m vs 28.0 ft8.53 m ).
- The Grampian 28 is heavier, displacing about 8% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the TES 28 Magnam carries the more powerful rig (17.6 vs 17.0), favouring lighter-air performance.
- The Grampian 28 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Grampian 28 rates better for offshore work (2.00 vs 2.14).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
