The Beneteau First 47.7 1999 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.

Size is the most obvious dividing line here. The Beneteau Oceanis 55 2012 measures 55,1 feet overall (2012), giving it roughly 7,0 additional feet of deck space compared to the Beneteau First 47.7 1999 at 48,1 feet (1999). Weight tells a clearer story for trailering families: the Beneteau Oceanis 55 2012 tips the scales at 36 454 lbs — 9 767 lbs less than the Beneteau First 47.7 1999 at 26 687 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 100 hp, the Beneteau First 47.7 1999 has a 25-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. Fuel capacity breaks the other way: the Beneteau Oceanis 55 2012 carries 106 gallons versus 62 gallons in the Beneteau First 47.7 1999. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

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 First 47.7 1999 caps at 14. 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.

Displacement is where these two sailboats genuinely part ways. The Beneteau Oceanis 55 2012 displaces 36 454 lbs — a 9 767-lb difference over the Beneteau First 47.7 1999 at 26 687 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 — 7,8 ft and 7,6 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

The Beneteau First 47.7 1999 uses Sloop rigging. Helm style differs too: the Beneteau First 47.7 1999 uses a 1 wheel versus a 2 wheels on the Beneteau Oceanis 55 2012. Wheel helms give better leverage and visibility on larger boats; tillers offer direct feedback and simplicity on smaller ones. For auxiliary power the Beneteau First 47.7 1999 carries a 100-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.

Hull speed is rated at 9,5 knots for the Beneteau Oceanis 55 2012 and 8,6 knots for the Beneteau First 47.7 1999. For extended cruising, water capacity matters: the Beneteau Oceanis 55 2012 carries 183 gallons versus 164 gallons on the Beneteau First 47.7 1999 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
