Detailed Evaluation & Buyer Recommendation

Sea Ray 300 Select EX 2008 vs Sea Ray 320 Sundancer 2005 — Same Brand, Different Boat

The Sea Ray 300 Select EX 2008 vs Sea Ray 320 Sundancer 2005 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.

The Sea Ray 300 Select EX 2008 carries a rated maximum of 320 hp. Engine data for the Sea Ray 320 Sundancer 2005 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Sea Ray 300 Select EX 2008 carries 13 gallons versus 2 gallons in the Sea Ray 320 Sundancer 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 320 Sundancer 2005 is rated for 10 passengers, while the Sea Ray 300 Select EX 2008 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 320 Sundancer 2005 could be the deciding factor.

Bottom line: Choose the Sea Ray 320 Sundancer 2005 if your priority is putting more people on the water — it handles 10 passengers and at 35,0 ft it has the deck room to back that rating up comfortably. The Sea Ray 300 Select EX 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
