The Beneteau First 310 1990 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.

Size is the most obvious dividing line here. The Beneteau Sense 46 2012 measures 46,4 feet overall (2012), giving it roughly 15,3 additional feet of deck space compared to the Beneteau First 310 1990 at 31,1 feet (1990). Weight tells a clearer story for trailering families: the Beneteau Sense 46 2012 tips the scales at 27 123 lbs — 18 966 lbs less 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.

The power gap is worth calling out. Rated to 75 hp, the Beneteau Sense 46 2012 has a 57-hp advantage over the Beneteau First 310 1990's 18-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 17 gallons in the Beneteau First 310 1990. 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 310 1990 caps at 9. 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.

Displacement is where these two sailboats genuinely part ways. The Beneteau Sense 46 2012 displaces 27 123 lbs — a 18 966-lb difference over the Beneteau First 310 1990 at 8 157 lbs. That gap separates two entirely different categories of sailing: the heavier boat is built for offshore passage-making and load-carrying, while the lighter hull rewards performance sailing and easier handling in lighter air.

Draft is a practical consideration that many buyers underestimate until they're already at the marina. The Beneteau Sense 46 2012 draws 7,1 ft, compared to 6,0 ft for the Beneteau First 310 1990. That 1,1-foot difference affects which anchorages you can access, which haul-out facilities will take you, and how carefully you need to read the tide tables in shallower cruising grounds.

The Beneteau First 310 1990 uses Sloop rigging. Helm style differs too: the Beneteau First 310 1990 uses a 1 tiller 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 18 hp on the Beneteau First 310 1990. 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 310 1990. For extended cruising, water capacity matters: the Beneteau First 310 1990 carries 45 gallons versus 14 gallons on the Beneteau Sense 46 2012 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
