The Beneteau First 34.7 2005 vs Beneteau Sense 46 2012 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 75 hp, the Beneteau Sense 46 2012 has a 54-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 Sense 46 2012 carries 52 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 Sense 46 2012 is rated for 14 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 Sense 46 2012 could be the deciding factor.

The Beneteau Sense 46 2012 has a documented displacement of 27 123 lbs. Displacement data wasn't available for the other boat in this comparison.

Both boats draw a similar depth - 6,7 ft and 7,1 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

The Beneteau First 34.7 2005 uses Sloop rigging. Helm style differs too: the Beneteau First 34.7 2005 uses a 1 wheel versus a 2 wheels on the Beneteau Sense 46 2012. Wheel helms give better leverage and visibility on larger boats; tillers offer direct feedback and simplicity on smaller ones. For auxiliary power the Beneteau Sense 46 2012 carries a 75-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.

Hull speed is rated at 8,7 knots for the Beneteau Sense 46 2012 and 7,2 knots for the Beneteau First 34.7 2005. For extended cruising, water capacity matters: the Beneteau Sense 46 2012 carries 140 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.
