The Beneteau First 21.7 S 2004 vs Beneteau First 300 Spirit 1994 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 300 Spirit 1994 measures 29,8 feet overall (1994), giving it roughly 9,7 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 300 Spirit 1994 tips the scales at 6 724 lbs — 3 980 lbs less than the Beneteau First 21.7 S 2004 at 2 744 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.

Both boats share a closely matched power ceiling — 20 hp for the Beneteau First 21.7 S 2004 and 18 hp for the Beneteau First 300 Spirit 1994. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 8 gal and 8 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Beneteau First 300 Spirit 1994 is rated for 9 passengers, while the Beneteau First 21.7 S 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 First 300 Spirit 1994 could be the deciding factor.

Displacement is where these two sailboats genuinely part ways. The Beneteau First 300 Spirit 1994 displaces 6 724 lbs — a 3 980-lb difference over the Beneteau First 21.7 S 2004 at 2 744 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 — 6,0 ft and 6,0 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

Sailboat comparisons often come down to details that specs don't fully capture — the quality of the standing rigging, the layout of the cockpit, and how the boat feels on a beat in 20 knots. A sea trial on both is strongly recommended.

For extended cruising, water capacity matters: the Beneteau First 300 Spirit 1994 carries 24 gallons versus 11 gallons on the Beneteau First 21.7 S 2004 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
