The Beneteau First 30 Fin keel 1977 vs Beneteau Oceanis 300 Shoal draft 1991 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 First 30 Fin keel 1977 at 29,5 ft versus Beneteau Oceanis 300 Shoal draft 1991 at 31,1 ft. Weight tells a clearer story for trailering families: the Beneteau First 30 Fin keel 1977 tips the scales at 8 995 lbs — 1 940 lbs more than the Beneteau Oceanis 300 Shoal draft 1991 at 7 055 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
Both boats share a closely matched power ceiling — 20 hp for the Beneteau First 30 Fin keel 1977 and 24 hp for the Beneteau Oceanis 300 Shoal draft 1991. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Beneteau Oceanis 300 Shoal draft 1991 carries 17 gallons versus 8 gallons in the Beneteau First 30 Fin keel 1977.
