Diamond Head vs Grand Raid 390: the short version
- The Diamond Head and Grand Raid 390 are close in length (12.8 ft3.91 m vs 12.8 ft3.90 m ).
- The Grand Raid 390 is heavier, displacing about 109% more, which usually means a steadier but slower-to-accelerate hull.
- By the capsize screening formula the Grand Raid 390 rates better for offshore work (2.52 vs 2.77).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
