The Beneteau First 30 Fin keel 1977 vs Beneteau First 310 1990 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 First 310 1990 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 — 838 lbs more than the Beneteau First 310 1990 at 8 157 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 18 hp for the Beneteau First 310 1990. 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 First 310 1990 carries 17 gallons versus 8 gallons in the Beneteau First 30 Fin keel 1977. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
