The Beneteau Oceanis 370 1989 vs Beneteau Swift Trawler 34S 2012 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
On paper these two are close siblings in the size department — Beneteau Oceanis 370 1989 at 35,7 ft versus Beneteau Swift Trawler 34S 2012 at 36,6 ft.
