Archambault A13 vs Gulfstar 43: the short version
- The Archambault A13 and Gulfstar 43 are close in length (43.0 ft13.11 m vs 43.3 ft13.21 m ).
- The Gulfstar 43 is heavier, displacing about 48% more, which usually means a steadier but slower-to-accelerate hull.
- By the capsize screening formula the Gulfstar 43 rates better for offshore work (1.73 vs 2.24).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
