The Beneteau First 18 SE 2018 vs Beneteau First 22 1978 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 First 22 1978 measures 22,1 feet overall (1978), giving it roughly 3,8 additional feet of deck space compared to the Beneteau First 18 SE 2018 at 18,3 feet (2018). Weight tells a clearer story for trailering families: the Beneteau First 22 1978 tips the scales at 3 946 lbs - 2 844 lbs less than the Beneteau First 18 SE 2018 at 1 102 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 First 22 1978 tops out at 10 hp. Engine specs for the Beneteau First 18 SE 2018 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 First 22 1978 is rated for 6 passengers, while the Beneteau First 18 SE 2018 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau First 22 1978 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Beneteau First 22 1978 displaces 3 946 lbs - a 2 844-lb difference over the Beneteau First 18 SE 2018 at 1 102 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.
Draft is a practical consideration that many buyers underestimate until they're already at the marina. The Beneteau First 18 SE 2018 draws 7,0 ft, compared to 3,6 ft for the Beneteau First 22 1978. That 3,4-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.
The Beneteau First 22 1978 has a documented auxiliary engine of 10 hp.
Both the Beneteau First 18 SE 2018 and Beneteau First 22 1978 are listed as trailerable, which opens up the freedom to explore different sailing grounds without paying for a permanent berth.
Bottom line: The Beneteau First 22 1978 is the offshore and bluewater choice - at 3 946 lbs displacement and 22 ft it has the load capacity, range, and seakeeping for extended passages. The Beneteau First 18 SE 2018 at 1 102 lbs is the more nimble, accessible option and is trailerable - easier to single-hand and better suited to coastal and inland sailing.
