The Beneteau First 22 1978 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 30,3 additional feet of deck space compared to the Beneteau First 22 1978 at 22,1 feet (1978). Weight tells a clearer story for trailering families: the Beneteau Sense 51 2016 tips the scales at 34 205 lbs — 30 259 lbs less than the Beneteau First 22 1978 at 3 946 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 70-hp advantage over the Beneteau First 22 1978's 10-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

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 First 22 1978 caps at 6. 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 30 259-lb difference over the Beneteau First 22 1978 at 3 946 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 3,6 ft for the Beneteau First 22 1978. That 3,6-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 22 1978 uses Sloop rigging. Helm style differs too: the Beneteau First 22 1978 uses a 1 tiller 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 10 hp on the Beneteau First 22 1978. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.

The Beneteau First 22 1978 is trailerable, giving it a significant lifestyle advantage for sailors who want to move between lakes, rivers, and coastal waters without committing to a marina slip. Hull speed is rated at 9,1 knots for the Beneteau Sense 51 2016 and 5,9 knots for the Beneteau First 22 1978. For extended cruising, water capacity matters: the Beneteau Sense 51 2016 carries 151 gallons versus 13 gallons on the Beneteau First 22 1978 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
