The Jeanneau Rush 1979 vs Jeanneau Sun Odyssey 319 2017 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.

On paper these two are close siblings in the size department — Jeanneau Rush 1979 at 31,4 ft versus Jeanneau Sun Odyssey 319 2017 at 32,2 ft. Weight tells a clearer story for trailering families: the Jeanneau Sun Odyssey 319 2017 tips the scales at 11 244 lbs — 4 189 lbs less than the Jeanneau Rush 1979 at 7 055 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.

Both boats share a closely matched power ceiling — 18 hp for the Jeanneau Rush 1979 and 21 hp for the Jeanneau Sun Odyssey 319 2017. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Jeanneau Sun Odyssey 319 2017 carries 26 gallons versus 7 gallons in the Jeanneau Rush 1979. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 9 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Displacement is where these two sailboats genuinely part ways. The Jeanneau Sun Odyssey 319 2017 displaces 11 244 lbs — a 4 189-lb difference over the Jeanneau Rush 1979 at 7 055 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 — 5,7 ft and 6,1 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

The Jeanneau Rush 1979 uses Sloop rigging. Helm style differs too: the Jeanneau Rush 1979 uses a 1 tiller versus a 1 wheel on the Jeanneau Sun Odyssey 319 2017. Wheel helms give better leverage and visibility on larger boats; tillers offer direct feedback and simplicity on smaller ones.

Hull speed is rated at 7,3 knots for the Jeanneau Sun Odyssey 319 2017 and 6,8 knots for the Jeanneau Rush 1979. For extended cruising, water capacity matters: the Jeanneau Rush 1979 carries 24 gallons versus 4 gallons on the Jeanneau Sun Odyssey 319 2017 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
