The Jeanneau Sun Fast 31 1990 vs Jeanneau Sun Kiss 47 Fin keel 1982 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 Sun Kiss 47 Fin keel 1982 measures 47,5 feet overall (1982), giving it roughly 22,1 additional feet of deck space compared to the Jeanneau Sun Fast 31 1990 at 25,4 feet (1990). Weight tells a clearer story for trailering families: the Jeanneau Sun Kiss 47 Fin keel 1982 tips the scales at 25 353 lbs — 18 519 lbs less than the Jeanneau Sun Fast 31 1990 at 6 834 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 55 hp, the Jeanneau Sun Kiss 47 Fin keel 1982 has a 37-hp advantage over the Jeanneau Sun Fast 31 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 Jeanneau Sun Kiss 47 Fin keel 1982 carries 57 gallons versus 13 gallons in the Jeanneau Sun Fast 31 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 Jeanneau Sun Kiss 47 Fin keel 1982 is rated for 14 passengers, while the Jeanneau Sun Fast 31 1990 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Jeanneau Sun Kiss 47 Fin keel 1982 could be the deciding factor.

Displacement is where these two sailboats genuinely part ways. The Jeanneau Sun Kiss 47 Fin keel 1982 displaces 25 353 lbs — a 18 519-lb difference over the Jeanneau Sun Fast 31 1990 at 6 834 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 — 5,8 ft and 6,1 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

The Jeanneau Sun Fast 31 1990 uses Sloop rigging. Helm style differs too: the Jeanneau Sun Fast 31 1990 uses a 1 tiller versus a 1 wheel on the Jeanneau Sun Kiss 47 Fin keel 1982. Wheel helms give better leverage and visibility on larger boats; tillers offer direct feedback and simplicity on smaller ones. For auxiliary power the Jeanneau Sun Kiss 47 Fin keel 1982 carries a 55-hp engine against 18 hp on the Jeanneau Sun Fast 31 1990. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.

Hull speed is rated at 8,2 knots for the Jeanneau Sun Kiss 47 Fin keel 1982 and 6,7 knots for the Jeanneau Sun Fast 31 1990. For extended cruising, water capacity matters: the Jeanneau Sun Kiss 47 Fin keel 1982 carries 164 gallons versus 26 gallons on the Jeanneau Sun Fast 31 1990 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
