Marlin 23 vs Tech Dinghy: the short version
- The Marlin 23 is the larger boat at 23.0 ft7.01 m LOA versus 12.0 ft3.66 m for the Tech Dinghy.
- The Marlin 23 is heavier, displacing about 1100% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Tech Dinghy carries the more powerful rig (29.0 vs 19.9), favouring lighter-air performance.
- By the capsize screening formula the Marlin 23 rates better for offshore work (1.99 vs 2.97).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
