Beneteau First 21.7 Swing keel 2004 vs Beneteau First Class 8 1994: Same Brand, Different Boat

The Beneteau First 21.7 Swing keel 2004 vs Beneteau First Class 8 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 Class 8 1994 measures 25,4 feet overall (1994), giving it roughly 4,4 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 First Class 8 1994 tips the scales at 3 100 lbs - 355 lbs less 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 Beneteau First 21.7 Swing keel 2004 carries a rated maximum of 11 hp. Engine data for the Beneteau First Class 8 1994 wasn't available in our records - check the manufacturer's spec sheet before sizing a motor.

For family outings this is probably the sharpest distinction between the two. The Beneteau First Class 8 1994 is rated for 7 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 First Class 8 1994 could be the deciding factor.

Both boats sit in a similar displacement bracket - 2 745 lbs for the Beneteau First 21.7 Swing keel 2004 and 3 100 lbs for the Beneteau First Class 8 1994. 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 - 5,1 ft and 5,8 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

The Beneteau First 21.7 Swing keel 2004 uses Sloop rigging. The Beneteau First 21.7 Swing keel 2004 has a documented auxiliary engine of 11 hp.

The Beneteau First 21.7 Swing keel 2004 is trailerable, giving it a significant lifestyle advantage for sailors who want to move between lakes, rivers, and coastal waters without committing to a marina slip.

Bottom line: The Beneteau First Class 8 1994 at 25,4 ft offers more living space, greater range, and a more substantial offshore capability. The Beneteau First 21.7 Swing keel 2004 at 21,0 ft is the easier, lower-cost option - simpler to crew, trailerable, and a strong choice for coastal and day sailing.

Beneteau First 21.7 Swing keel 2004 vs Beneteau First Class 8 1994 - Common Questions

Which is the larger boat - the Beneteau First 21.7 Swing keel 2004 or the Beneteau First Class 8 1994?
The Beneteau First Class 8 1994 is the longer of the two at 25,4 feet overall. The Beneteau First 21.7 Swing keel 2004 comes in at 21,0 feet, making it roughly 4,4 ft shorter - a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer - the Beneteau First 21.7 Swing keel 2004 or the Beneteau First Class 8 1994?
For trailering, the Beneteau First 21.7 Swing keel 2004 has the edge at 2 745 lbs dry weight versus 3 100 lbs for the Beneteau First Class 8 1994. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
What is the maximum horsepower rating for these boats?
The Beneteau First 21.7 Swing keel 2004 has a documented max rating of 11 hp. Engine specifications for the Beneteau First Class 8 1994 were not available in our database - check the OEM spec sheet or manufacturer's website for confirmation.
How many people can each boat hold?
The Beneteau First 21.7 Swing keel 2004 is Coast Guard rated for 6 passengers, while the Beneteau First Class 8 1994 is certified for 7. Note that legal capacity and comfortable capacity aren't always the same thing - on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat has the deeper draft - the Beneteau First 21.7 Swing keel 2004 or the Beneteau First Class 8 1994?
The Beneteau First Class 8 1994 has the deeper draft at 5,8 ft, versus 5,1 ft for the Beneteau First 21.7 Swing keel 2004. A deeper draft generally means better upwind performance and stability, but limits access to shallow anchorages and some marina berths. Always check the controlling depth of your home port and favourite cruising grounds before committing.
Is the Beneteau First 21.7 Swing keel 2004 or the Beneteau First Class 8 1994 better suited for offshore sailing?
For offshore work, displacement and construction are the primary indicators. The Beneteau First Class 8 1994 at 3 100 lbs displacement is the heavier, more load-carrying design - generally better suited to extended passages where seakeeping and provisioning capacity matter most. The Beneteau First 21.7 Swing keel 2004 at 2 745 lbs will typically be livelier and more responsive in lighter conditions.
Can the Beneteau First 21.7 Swing keel 2004 be trailered?
The Beneteau First 21.7 Swing keel 2004 is listed as trailerable, giving owners the flexibility to launch from any suitable ramp and avoid permanent berthing costs. The Beneteau First Class 8 1994 is not listed as trailerable - it will need a marina berth or mooring.
Which boat is wider, and does it affect trailering?
The Beneteau First Class 8 1994 measures 98" wide, compared to 97" for the Beneteau First 21.7 Swing keel 2004. The US standard-width towing limit is 8’6" (102") in most states - anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Are the Beneteau First 21.7 Swing keel 2004 and Beneteau First Class 8 1994 from the same manufacturer?
Yes - both the Beneteau First 21.7 Swing keel 2004 and the Beneteau First Class 8 1994 are built by Beneteau. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
