The Beneteau First 21.7 Swing keel 2004 vs Beneteau Wizz 1981 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 21.7 Swing keel 2004 measures 21,0 feet overall (2004), giving it roughly 6,5 additional feet of deck space compared to the Beneteau Wizz 1981 at 14,5 feet (1981). Weight tells a clearer story for trailering families: the Beneteau First 21.7 Swing keel 2004 tips the scales at 2 745 lbs — 2 591 lbs more than the Beneteau Wizz 1981 at 154 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 21.7 Swing keel 2004 carries a rated maximum of 11 hp. Engine data for the Beneteau Wizz 1981 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.

If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau First 21.7 Swing keel 2004 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Beneteau First 21.7 Swing keel 2004 displaces 2 745 lbs — a 2 591-lb difference over the Beneteau Wizz 1981 at 154 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.
The Beneteau First 21.7 Swing keel 2004 is rigged as a Sloop while the Beneteau Wizz 1981 carries fractional_rig_sloop rigging — a meaningful difference in sail handling complexity, upwind performance, and the size of crew you'll need to work the boat comfortably.

Both the Beneteau First 21.7 Swing keel 2004 and Beneteau Wizz 1981 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 21.7 Swing keel 2004 is the offshore and bluewater choice — at 2 745 lbs displacement and 21 ft it has the load capacity, range, and seakeeping for extended passages. The Beneteau Wizz 1981 at 154 lbs is the more nimble, accessible option and is trailerable — easier to single-hand and better suited to coastal and inland sailing.
