The Beneteau Cyclades 50.4 2007 vs Beneteau Oceanis 55 2012 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.
The power gap is worth calling out. Rated to 110 hp, the Beneteau Cyclades 50.4 2007 has a 35-hp advantage over the Beneteau Oceanis 55 2012's 75-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 105 gal and 106 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Beneteau Oceanis 55 2012 is rated for 16 passengers, while the Beneteau Cyclades 50.4 2007 caps at 15. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Oceanis 55 2012 could be the deciding factor.
The Beneteau Oceanis 55 2012 has a documented displacement of 36 454 lbs. Displacement data wasn't available for the other boat in this comparison.
Draft is a practical consideration that many buyers underestimate until they're already at the marina. The Beneteau Oceanis 55 2012 draws 7,6 ft, compared to 6,5 ft for the Beneteau Cyclades 50.4 2007. That 1,1-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.
For auxiliary power the Beneteau Cyclades 50.4 2007 carries a 110-hp engine against 75 hp on the Beneteau Oceanis 55 2012. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.
For extended cruising, water capacity matters: the Beneteau Cyclades 50.4 2007 carries 258 gallons versus 183 gallons on the Beneteau Oceanis 55 2012 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
Bottom line: The Beneteau Oceanis 55 2012 at 55,1 ft offers more living space, greater range, and a more substantial offshore capability. The Beneteau Cyclades 50.4 2007 at 51,3 ft is the easier, lower-cost option — simpler to crew and a strong choice for coastal and day sailing.
