The Beneteau First 34.7 2005 vs Beneteau First 40.7 1997 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.
Both boats share a closely matched power ceiling — 21 hp for the Beneteau First 34.7 2005 and 40 hp for the Beneteau First 40.7 1997. 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 40.7 1997 carries 37 gallons versus 20 gallons in the Beneteau First 34.7 2005. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Beneteau First 40.7 1997 is rated for 11 passengers, while the Beneteau First 34.7 2005 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau First 40.7 1997 could be the deciding factor.

Hull speed is rated at 7,9 knots for the Beneteau First 40.7 1997 and 7,2 knots for the Beneteau First 34.7 2005. For extended cruising, water capacity matters: the Beneteau First 40.7 1997 carries 72 gallons versus 26 gallons on the Beneteau First 34.7 2005 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
