The Beneteau First 34.7 2005 vs Beneteau Oceanis 35 2014 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 30 hp for the Beneteau Oceanis 35 2014. 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 35 2014 carries 34 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.
Both boats are rated for 10 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
The Beneteau Oceanis 35 2014 has a documented displacement of 12 198 lbs. Displacement data wasn't available for the other boat in this comparison.

Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.
