The Jeanneau Rush 1979 vs Jeanneau Sun Odyssey 37 2001 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 Odyssey 37 2001 measures 37,5 feet overall (2001), giving it roughly 6,1 additional feet of deck space compared to the Jeanneau Rush 1979 at 31,4 feet (1979). Weight tells a clearer story for trailering families: the Jeanneau Sun Odyssey 37 2001 tips the scales at 13 779 lbs — 6 724 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.

The power gap is worth calling out. Rated to 55 hp, the Jeanneau Sun Odyssey 37 2001 has a 37-hp advantage over the Jeanneau Rush 1979'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 Odyssey 37 2001 carries 36 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.

For family outings this is probably the sharpest distinction between the two. The Jeanneau Sun Odyssey 37 2001 is rated for 11 passengers, while the Jeanneau Rush 1979 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Jeanneau Sun Odyssey 37 2001 could be the deciding factor.

Displacement is where these two sailboats genuinely part ways. The Jeanneau Sun Odyssey 37 2001 displaces 13 779 lbs — a 6 724-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 4,9 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

The Jeanneau Rush 1979 uses Sloop rigging. For auxiliary power the Jeanneau Sun Odyssey 37 2001 carries a 55-hp engine against 18 hp on the Jeanneau Rush 1979. 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 Jeanneau Sun Odyssey 37 2001 carries 85 gallons versus 24 gallons on the Jeanneau Rush 1979 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
