Alpha 230 A vs Tech Dinghy: the short version
- The Alpha 230 A and Tech Dinghy are close in length (12.0 ft3.67 m vs 12.0 ft3.66 m ).
- The Tech Dinghy is heavier, displacing about 468% more, which usually means a steadier but slower-to-accelerate hull.
- By the capsize screening formula the Alpha 230 A rates better for offshore work (2.49 vs 2.97).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
