The Sea Ray 290 Sundancer 2007 vs Sea Ray Express Cruiser 340 1988 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 — Sea Ray 290 Sundancer 2007 at 31,0 ft versus Sea Ray Express Cruiser 340 1988 at 34,0 ft. Weight tells a clearer story for trailering families: the Sea Ray Express Cruiser 340 1988 tips the scales at 10 100 lbs — 9 175 lbs less than the Sea Ray 290 Sundancer 2007 at 925 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 340 hp, the Sea Ray Express Cruiser 340 1988 has a 42-hp advantage over the Sea Ray 290 Sundancer 2007's 298-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sea Ray 290 Sundancer 2007 carries 125 gallons versus 25 gallons in the Sea Ray Express Cruiser 340 1988. 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 Sea Ray Express Cruiser 340 1988 is rated for 10 passengers, while the Sea Ray 290 Sundancer 2007 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray Express Cruiser 340 1988 could be the deciding factor.
