The Beneteau First 21.7 S 2004 vs Beneteau First Class 7.5 2008 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 Class 7.5 2008 measures 25,9 feet overall (2008), giving it roughly 5,8 additional feet of deck space compared to the Beneteau First 21.7 S 2004 at 20,1 feet (2004). Weight tells a clearer story for trailering families: the Beneteau First 21.7 S 2004 tips the scales at 2 744 lbs — 165 lbs more than the Beneteau First Class 7.5 2008 at 2 579 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 S 2004 carries a rated maximum of 20 hp. Engine data for the Beneteau First Class 7.5 2008 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 Class 7.5 2008 could be the deciding factor.

Both boats sit in a similar displacement bracket — 2 744 lbs for the Beneteau First 21.7 S 2004 and 2 579 lbs for the Beneteau First Class 7.5 2008. Comparable displacement means broadly similar seakeeping behaviour and load capacity, though hull form and ballast ratio will still produce noticeably different sailing characteristics.

Both boats draw a similar depth — 6,0 ft and 6,7 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

The Beneteau First 21.7 S 2004 has a documented auxiliary engine of 20 hp.
