Diamond Head vs Impulse: the short version
- The Diamond Head and Impulse are close in length (12.8 ft3.91 m vs 13.1 ft4.00 m ).
- The Impulse is heavier, displacing about 373% more, which usually means a steadier but slower-to-accelerate hull.
- By the capsize screening formula the Diamond Head rates better for offshore work (2.77 vs 4.20).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
