The Sea Ray 290 Amberjack 2010 vs Sea Ray SLX 400 2023 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 Sea Ray SLX 400 2023 measures 39,6 feet overall (2023), giving it roughly 8,3 additional feet of deck space compared to the Sea Ray 290 Amberjack 2010 at 31,3 feet (2010). Weight tells a clearer story for trailering families: the Sea Ray SLX 400 2023 tips the scales at 20 794 lbs — 8 579 lbs less than the Sea Ray 290 Amberjack 2010 at 12 215 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 Sea Ray SLX 400 2023 has a 73-hp advantage over the Sea Ray 290 Amberjack 2010's 307-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 25 gal and 25 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Sea Ray SLX 400 2023 is rated for 12 passengers, while the Sea Ray 290 Amberjack 2010 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 SLX 400 2023 could be the deciding factor.
