The Sea Ray Select 200 2005 vs Sea Ray Sundeck 290 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.
Size is the most obvious dividing line here. The Sea Ray Sundeck 290 2017 measures 29,2 feet overall (2017), giving it roughly 9,2 additional feet of deck space compared to the Sea Ray Select 200 2005 at 20,0 feet (2005). Weight tells a clearer story for trailering families: the Sea Ray Sundeck 290 2017 tips the scales at 6 471 lbs — 2 921 lbs less than the Sea Ray Select 200 2005 at 3 550 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 Sundeck 290 2017 has a 130-hp advantage over the Sea Ray Select 200 2005's 250-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 Sundeck 290 2017 carries 85 gallons versus 37 gallons in the Sea Ray Select 200 2005. 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 Sundeck 290 2017 is rated for 8 passengers, while the Sea Ray Select 200 2005 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray Sundeck 290 2017 could be the deciding factor.
Bottom line: Choose the Sea Ray Sundeck 290 2017 if your priority is putting more people on the water — it handles 8 passengers and at 29,2 ft it has the deck room to back that rating up comfortably. The Sea Ray Select 200 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
