The Beneteau First 45 2007 vs Beneteau Oceanis 48 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.
On paper these two are close siblings in the size department — Beneteau First 45 2007 at 46,2 ft versus Beneteau Oceanis 48 2011 at 47,1 ft. Weight tells a clearer story for trailering families: the Beneteau Oceanis 48 2011 tips the scales at 27 765 lbs — 2 280 lbs less than the Beneteau First 45 2007 at 25 485 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 75 hp, the Beneteau Oceanis 48 2011 has a 21-hp advantage over the Beneteau First 45 2007's 54-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 53 gal and 53 gal — so range won't be a tiebreaker here.
Both boats are rated for 14 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Displacement is where these two sailboats genuinely part ways. The Beneteau Oceanis 48 2011 displaces 27 765 lbs — a 2 280-lb difference over the Beneteau First 45 2007 at 25 485 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 — 7,1 ft and 7,1 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.
The Beneteau First 45 2007 uses Sloop rigging. For auxiliary power the Beneteau Oceanis 48 2011 carries a 75-hp engine against 54 hp on the Beneteau First 45 2007. 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 9,0 knots for the Beneteau Oceanis 48 2011 and 8,4 knots for the Beneteau First 45 2007. For extended cruising, water capacity matters: the Beneteau First 45 2007 carries 151 gallons versus 98 gallons on the Beneteau Oceanis 48 2011 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
Bottom line: The Beneteau Oceanis 48 2011 is the offshore and bluewater choice — at 27 765 lbs displacement and 47 ft it has the load capacity, range, and seakeeping for extended passages. The Beneteau First 45 2007 at 25 485 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
