The Beneteau Oceanis 370 1989 vs Beneteau Sense 51 2016 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 51 2016 measures 52,4 feet overall (2016), giving it roughly 16,7 additional feet of deck space compared to the Beneteau Oceanis 370 1989 at 35,7 feet (1989). Weight tells a clearer story for trailering families: the Beneteau Sense 51 2016 tips the scales at 34 205 lbs — 22 961 lbs less than the Beneteau Oceanis 370 1989 at 11 244 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 80 hp, the Beneteau Sense 51 2016 has a 53-hp advantage over the Beneteau Oceanis 370 1989's 27-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 51 2016 carries 110 gallons versus 26 gallons in the Beneteau Oceanis 370 1989. 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 51 2016 is rated for 15 passengers, while the Beneteau Oceanis 370 1989 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 51 2016 could be the deciding factor.

Displacement is where these two sailboats genuinely part ways. The Beneteau Sense 51 2016 displaces 34 205 lbs — a 22 961-lb difference over the Beneteau Oceanis 370 1989 at 11 244 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 51 2016 draws 7,2 ft, compared to 5,1 ft for the Beneteau Oceanis 370 1989. That 2,1-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 Oceanis 370 1989 uses Sloop rigging. Helm style differs too: the Beneteau Oceanis 370 1989 uses a 1 wheel versus a 2 wheels on the Beneteau Sense 51 2016. 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 51 2016 carries a 80-hp engine against 27 hp on the Beneteau Oceanis 370 1989. 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 9,1 knots for the Beneteau Sense 51 2016 and 7,5 knots for the Beneteau Oceanis 370 1989. For extended cruising, water capacity matters: the Beneteau Sense 51 2016 carries 151 gallons versus 106 gallons on the Beneteau Oceanis 370 1989 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
