The Jeanneau Leader 46 2021 vs Jeanneau Sun Fast 17 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 Jeanneau Leader 46 2021 measures 46,1 feet overall (2021), giving it roughly 28,4 additional feet of deck space compared to the Jeanneau Sun Fast 17 1994 at 17,7 feet (1994). Weight tells a clearer story for trailering families: the Jeanneau Leader 46 2021 tips the scales at 23 369 lbs — 22 046 lbs more than the Jeanneau Sun Fast 17 1994 at 1 323 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 380 hp, the Jeanneau Leader 46 2021 has a 376-hp advantage over the Jeanneau Sun Fast 17 1994's 4-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 Jeanneau Leader 46 2021 is rated for 14 passengers, while the Jeanneau Sun Fast 17 1994 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Jeanneau Leader 46 2021 could be the deciding factor.

Displacement is where these two sailboats genuinely part ways. The Jeanneau Leader 46 2021 displaces 23 369 lbs — a 22 046-lb difference over the Jeanneau Sun Fast 17 1994 at 1 323 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 — 3,7 ft and 3,4 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

For auxiliary power the Jeanneau Leader 46 2021 carries a 380-hp engine against 4 hp on the Jeanneau Sun Fast 17 1994. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.

The Jeanneau Sun Fast 17 1994 is trailerable — a genuine advantage for sailors who prefer to keep their boat at home or explore multiple sailing venues.
