The Beneteau First Class Challange 1989 vs Beneteau Sense 55 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 55 2016 measures 58,4 feet overall (2016), giving it roughly 28,4 additional feet of deck space compared to the Beneteau First Class Challange 1989 at 30,0 feet (1989). Weight tells a clearer story for trailering families: the Beneteau Sense 55 2016 tips the scales at 39 474 lbs — 34 183 lbs less than the Beneteau First Class Challange 1989 at 5 291 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 Beneteau Sense 55 2016 tops out at 120 hp. Engine specs for the Beneteau First Class Challange 1989 aren't listed — confirm with a dealer before selecting an outboard.

If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Sense 55 2016 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Beneteau Sense 55 2016 displaces 39 474 lbs — a 34 183-lb difference over the Beneteau First Class Challange 1989 at 5 291 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.
The Beneteau First Class Challange 1989 is rigged as a Fractional Sloop while the Beneteau Sense 55 2016 carries Sloop rigging — a meaningful difference in sail handling complexity, upwind performance, and the size of crew you'll need to work the boat comfortably.

Bottom line: The Beneteau Sense 55 2016 is the offshore and bluewater choice — at 39 474 lbs displacement and 58 ft it has the load capacity, range, and seakeeping for extended passages. The Beneteau First Class Challange 1989 at 5 291 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
