Detailed Evaluation & Buyer Recommendation
Sea Ray 185 Outboard Sport 2006 vs Sea Ray 310 Sundancer 2008 — Same Brand, Different Boat
The Sea Ray 185 Outboard Sport 2006 vs Sea Ray 310 Sundancer 2008 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 310 Sundancer 2008 measures 33,0 feet overall (2008), giving it roughly 15,0 additional feet of deck space compared to the Sea Ray 185 Outboard Sport 2006 at 18,0 feet (2006). Weight tells a clearer story for trailering families: the Sea Ray 185 Outboard Sport 2006 tips the scales at 185 lbs — 171 lbs more than the Sea Ray 310 Sundancer 2008 at 14 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 320 hp, the Sea Ray 310 Sundancer 2008 has a 185-hp advantage over the Sea Ray 185 Outboard Sport 2006's 135-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 2 gal and 2 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Sea Ray 310 Sundancer 2008 is rated for 10 passengers, while the Sea Ray 185 Outboard Sport 2006 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 310 Sundancer 2008 could be the deciding factor.
Bottom line: Choose the Sea Ray 310 Sundancer 2008 if your priority is putting more people on the water — it handles 10 passengers and at 33,0 ft it has the deck room to back that rating up comfortably. The Sea Ray 185 Outboard Sport 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
