The Beneteau First Class 7.5 2008 vs Beneteau Oceanis 45 2011 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 Oceanis 45 2011 measures 45,9 feet overall (2011), giving it roughly 20,0 additional feet of deck space compared to the Beneteau First Class 7.5 2008 at 25,9 feet (2008). Weight tells a clearer story for trailering families: the Beneteau Oceanis 45 2011 tips the scales at 23 257 lbs — 20 678 lbs less than the Beneteau First Class 7.5 2008 at 2 579 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 Oceanis 45 2011 tops out at 54 hp. Engine specs for the Beneteau First Class 7.5 2008 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 Oceanis 45 2011 is rated for 13 passengers, while the Beneteau First Class 7.5 2008 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Oceanis 45 2011 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Beneteau Oceanis 45 2011 displaces 23 257 lbs — a 20 678-lb difference over the Beneteau First Class 7.5 2008 at 2 579 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 — 6,7 ft and 7,5 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.
The Beneteau First Class 7.5 2008 is rigged as a Fractional Sloop while the Beneteau Oceanis 45 2011 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 Oceanis 45 2011 has a documented auxiliary engine of 54 hp.
Bottom line: The Beneteau Oceanis 45 2011 is the offshore and bluewater choice — at 23 257 lbs displacement and 46 ft it has the load capacity, range, and seakeeping for extended passages. The Beneteau First Class 7.5 2008 at 2 579 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
