The Beneteau First Class 10 1987 vs Beneteau Idylle 13.50 1984 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 Idylle 13.50 1984 measures 44,4 feet overall (1984), giving it roughly 10,1 additional feet of deck space compared to the Beneteau First Class 10 1987 at 34,3 feet (1987). Weight tells a clearer story for trailering families: the Beneteau Idylle 13.50 1984 tips the scales at 24 251 lbs — 17 351 lbs less than the Beneteau First Class 10 1987 at 6 900 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 Idylle 13.50 1984 tops out at 50 hp. Engine specs for the Beneteau First Class 10 1987 aren't listed — confirm with a dealer before selecting an outboard.
For family outings this is probably the sharpest distinction between the two. The Beneteau Idylle 13.50 1984 is rated for 13 passengers, while the Beneteau First Class 10 1987 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Idylle 13.50 1984 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Beneteau Idylle 13.50 1984 displaces 24 251 lbs — a 17 351-lb difference over the Beneteau First Class 10 1987 at 6 900 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.
Both boats draw a similar depth — 5,8 ft and 5,1 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.
The Beneteau First Class 10 1987 is rigged as a Fractional Sloop while the Beneteau Idylle 13.50 1984 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. The Beneteau Idylle 13.50 1984 has a documented auxiliary engine of 50 hp.
Bottom line: The Beneteau Idylle 13.50 1984 is the offshore and bluewater choice — at 24 251 lbs displacement and 44 ft it has the load capacity, range, and seakeeping for extended passages. The Beneteau First Class 10 1987 at 6 900 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
