The Beneteau First 310 1990 vs Beneteau Flyer 6 Sundeck 2023 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 310 1990 measures 31,1 feet overall (1990), giving it roughly 11,4 additional feet of deck space compared to the Beneteau Flyer 6 Sundeck 2023 at 19,7 feet (2023). Weight tells a clearer story for trailering families: the Beneteau First 310 1990 tips the scales at 8 157 lbs - 5 400 lbs more than the Beneteau Flyer 6 Sundeck 2023 at 2 757 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 140 hp, the Beneteau Flyer 6 Sundeck 2023 has a 122-hp advantage over the Beneteau First 310 1990's 18-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Beneteau Flyer 6 Sundeck 2023 carries 26 gallons versus 17 gallons in the Beneteau First 310 1990. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Beneteau First 310 1990 is rated for 9 passengers, while the Beneteau Flyer 6 Sundeck 2023 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 310 1990 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Beneteau First 310 1990 displaces 8 157 lbs - a 5 400-lb difference over the Beneteau Flyer 6 Sundeck 2023 at 2 757 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.
Draft is a practical consideration that many buyers underestimate until they're already at the marina. The Beneteau First 310 1990 draws 6,0 ft, compared to 2,7 ft for the Beneteau Flyer 6 Sundeck 2023. That 3,3-foot difference affects which anchorages you can access, which haul-out facilities will take you, and how carefully you need to read the tide tables in shallower cruising grounds.
The Beneteau First 310 1990 uses Sloop rigging. For auxiliary power the Beneteau Flyer 6 Sundeck 2023 carries a 140-hp engine against 18 hp on the Beneteau First 310 1990. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.
For extended cruising, water capacity matters: the Beneteau First 310 1990 carries 45 gallons versus 13 gallons on the Beneteau Flyer 6 Sundeck 2023 - a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
Bottom line: The Beneteau First 310 1990 is the offshore and bluewater choice - at 8 157 lbs displacement and 31 ft it has the load capacity, range, and seakeeping for extended passages. The Beneteau Flyer 6 Sundeck 2023 at 2 757 lbs is the more nimble, accessible option - easier to single-hand and better suited to coastal and inland sailing.
