The Beneteau First Class 10 1987 vs Beneteau Gran Turismo 46 2020 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 Gran Turismo 46 2020 measures 48,6 feet overall (2020), giving it roughly 14,3 additional feet of deck space compared to the Beneteau First Class 10 1987 at 34,3 feet (1987). Weight tells a clearer story for trailering families: the Beneteau Gran Turismo 46 2020 tips the scales at 22 180 lbs — 15 280 lbs less than the Beneteau First Class 10 1987 at 6 900 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 Gran Turismo 46 2020 tops out at 435 hp. Engine specs for the Beneteau First Class 10 1987 aren't listed — confirm with a dealer before selecting an outboard.
For family outings this is probably the sharpest distinction between the two. The Beneteau Gran Turismo 46 2020 is rated for 14 passengers, while the Beneteau First Class 10 1987 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Gran Turismo 46 2020 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Beneteau Gran Turismo 46 2020 displaces 22 180 lbs — a 15 280-lb difference over the Beneteau First Class 10 1987 at 6 900 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 Class 10 1987 draws 5,8 ft, compared to 3,8 ft for the Beneteau Gran Turismo 46 2020. That 2,0-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 Class 10 1987 uses Fractional Sloop rigging. The Beneteau Gran Turismo 46 2020 has a documented auxiliary engine of 435 hp.
Bottom line: The Beneteau Gran Turismo 46 2020 is the offshore and bluewater choice — at 22 180 lbs displacement and 49 ft it has the load capacity, range, and seakeeping for extended passages. The Beneteau First Class 10 1987 at 6 900 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
