The Beneteau Cyclades 39.3 2007 vs Beneteau First 21.7 Swing keel 2004 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 Cyclades 39.3 2007 measures 39,3 feet overall (2007), giving it roughly 18,3 additional feet of deck space compared to the Beneteau First 21.7 Swing keel 2004 at 21,0 feet (2004). Weight tells a clearer story for trailering families: the Beneteau Cyclades 39.3 2007 tips the scales at 15 642 lbs — 12 897 lbs more than the Beneteau First 21.7 Swing keel 2004 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 40 hp, the Beneteau Cyclades 39.3 2007 has a 29-hp advantage over the Beneteau First 21.7 Swing keel 2004's 11-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 Cyclades 39.3 2007 is rated for 11 passengers, while the Beneteau First 21.7 Swing keel 2004 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Cyclades 39.3 2007 could be the deciding factor.

Displacement is where these two sailboats genuinely part ways. The Beneteau Cyclades 39.3 2007 displaces 15 642 lbs — a 12 897-lb difference over the Beneteau First 21.7 Swing keel 2004 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.

The Beneteau Cyclades 39.3 2007 is rigged as a Fractional Sloop while the Beneteau First 21.7 Swing keel 2004 carries Sloop rigging — a meaningful difference in sail handling complexity, upwind performance, and the size of crew you'll need to work the boat comfortably. For auxiliary power the Beneteau Cyclades 39.3 2007 carries a 40-hp engine against 11 hp on the Beneteau First 21.7 Swing keel 2004. 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 21.7 Swing keel 2004 is trailerable — a genuine advantage for sailors who prefer to keep their boat at home or explore multiple sailing venues. For extended cruising, water capacity matters: the Beneteau Cyclades 39.3 2007 carries 87 gallons versus 9 gallons on the Beneteau First 21.7 Swing keel 2004 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
