Sea Ray 240 Sundeck 2005 vs Sea Ray SLX 280 2022 — Same Brand, Different Boat

The Sea Ray 240 Sundeck 2005 vs Sea Ray SLX 280 2022 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 240 Sundeck 2005 at 26,0 ft versus Sea Ray SLX 280 2022 at 28,6 ft. Weight tells a clearer story for trailering families: the Sea Ray SLX 280 2022 tips the scales at 7 018 lbs — 6 550 lbs less than the Sea Ray 240 Sundeck 2005 at 468 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 Sea Ray SLX 280 2022 tops out at 350 hp. Engine specs for the Sea Ray 240 Sundeck 2005 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Sea Ray 240 Sundeck 2005 carries 65 gallons versus 9 gallons in the Sea Ray SLX 280 2022. 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 240 Sundeck 2005 is rated for 12 passengers, while the Sea Ray SLX 280 2022 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 240 Sundeck 2005 could be the deciding factor.

Bottom line: Choose the Sea Ray 240 Sundeck 2005 if your priority is putting more people on the water — it handles 12 passengers and at 26,0 ft it has the deck room to back that rating up comfortably. The Sea Ray SLX 280 2022 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.

The Sea Ray SLX 280 2022 is the longer of the two at 28,6 feet overall. The Sea Ray 240 Sundeck 2005 comes in at 26,0 feet, making it roughly 2,6 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray 240 Sundeck 2005 or the Sea Ray SLX 280 2022?
For trailering, the Sea Ray 240 Sundeck 2005 has the edge at 468 lbs dry weight versus 7 018 lbs for the Sea Ray SLX 280 2022. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.

How many people can each boat hold?
The Sea Ray 240 Sundeck 2005 is Coast Guard rated for 12 passengers, while the Sea Ray SLX 280 2022 is certified for 8. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.

The Sea Ray SLX 280 2022 measures 109" wide, compared to 102" for the Sea Ray 240 Sundeck 2005. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
