Detailed Evaluation & Buyer Recommendation

Beneteau First 34.7 2005 vs Beneteau Monte Carlo 5 2020 — Same Brand, Different Boat

The Beneteau First 34.7 2005 vs Beneteau Monte Carlo 5 2020 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.

The power gap is worth calling out. Rated to 435 hp, the Beneteau Monte Carlo 5 2020 has a 414-hp advantage over the Beneteau First 34.7 2005's 21-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Beneteau Monte Carlo 5 2020 carries 344 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 Monte Carlo 5 2020 is rated for 15 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 Monte Carlo 5 2020 could be the deciding factor.

The Beneteau Monte Carlo 5 2020 has a documented displacement of 31 381 lbs. Displacement data wasn't available for the other boat in this comparison.

The Beneteau First 34.7 2005 uses Sloop rigging. For auxiliary power the Beneteau Monte Carlo 5 2020 carries a 435-hp engine against 21 hp on the Beneteau First 34.7 2005. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.

For extended cruising, water capacity matters: the Beneteau Monte Carlo 5 2020 carries 158 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.

Bottom line: The Beneteau Monte Carlo 5 2020 at 49,6 ft offers more living space, greater range, and a more substantial offshore capability. The Beneteau First 34.7 2005 at 34,0 ft is the easier, lower-cost option — simpler to crew and a strong choice for coastal and day sailing.
