The Beneteau Oceanis 370 1989 vs Beneteau Océanis 381 Classic Classic 1996 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 Océanis 381 Classic Classic 1996 at 38,6 ft.

Both boats share a closely matched power ceiling - 27 hp for the Beneteau Oceanis 370 1989 and 42 hp for the Beneteau Océanis 381 Classic Classic 1996.
