The Beneteau First 20 2013 vs Beneteau Oceanis 390 1987 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 390 1987 measures 38,2 feet overall (1987), giving it roughly 17,2 additional feet of deck space compared to the Beneteau First 20 2013 at 21,0 feet (2013). Weight tells a clearer story for trailering families: the Beneteau Oceanis 390 1987 tips the scales at 14 330 lbs — 11 585 lbs less than the Beneteau First 20 2013 at 2 745 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 50 hp, the Beneteau Oceanis 390 1987 has a 40-hp advantage over the Beneteau First 20 2013's 10-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Beneteau Oceanis 390 1987 is rated for 11 passengers, while the Beneteau First 20 2013 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Oceanis 390 1987 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Beneteau Oceanis 390 1987 displaces 14 330 lbs — a 11 585-lb difference over the Beneteau First 20 2013 at 2 745 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 — 5,1 ft and 5,5 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.
Helm style differs too: the Beneteau First 20 2013 uses a 1 tiller versus a 1 wheel on the Beneteau Oceanis 390 1987. Wheel helms give better leverage and visibility on larger boats; tillers offer direct feedback and simplicity on smaller ones. For auxiliary power the Beneteau Oceanis 390 1987 carries a 50-hp engine against 10 hp on the Beneteau First 20 2013. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.
The Beneteau First 20 2013 is trailerable, giving it a significant lifestyle advantage for sailors who want to move between lakes, rivers, and coastal waters without committing to a marina slip. Hull speed is rated at 7,7 knots for the Beneteau Oceanis 390 1987 and 6,0 knots for the Beneteau First 20 2013.
Bottom line: The Beneteau Oceanis 390 1987 is the offshore and bluewater choice — at 14 330 lbs displacement and 38 ft it has the load capacity, range, and seakeeping for extended passages. The Beneteau First 20 2013 at 2 745 lbs is the more nimble, accessible option and is trailerable — easier to single-hand and better suited to coastal and inland sailing.
