Sea Ray 305 Sundancer 2012 vs Sea Ray Sundancer 350 Coupe 2021 — Same Brand, Different Boat

The Sea Ray 305 Sundancer 2012 vs Sea Ray Sundancer 350 Coupe 2021 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 305 Sundancer 2012 at 33,3 ft versus Sea Ray Sundancer 350 Coupe 2021 at 35,1 ft. Weight tells a clearer story for trailering families: the Sea Ray Sundancer 350 Coupe 2021 tips the scales at 18 792 lbs — 17 929 lbs less than the Sea Ray 305 Sundancer 2012 at 863 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 350 hp, the Sea Ray Sundancer 350 Coupe 2021 has a 90-hp advantage over the Sea Ray 305 Sundancer 2012's 260-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 Sundancer 350 Coupe 2021 carries 214 gallons versus 1 gallons in the Sea Ray 305 Sundancer 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 10 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: Performance buyers should lean toward the Sea Ray Sundancer 350 Coupe 2021 and its 350-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Sea Ray 305 Sundancer 2012 with its 260-hp rating is the more economical daily driver.

Sea Ray 305 Sundancer 2012 vs Sea Ray Sundancer 350 Coupe 2021 — Common Questions

Which is the larger boat — the Sea Ray 305 Sundancer 2012 or the Sea Ray Sundancer 350 Coupe 2021?
The Sea Ray Sundancer 350 Coupe 2021 is the longer of the two at 35,1 feet overall. The Sea Ray 305 Sundancer 2012 comes in at 33,3 feet, making it roughly 1,9 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray 305 Sundancer 2012 or the Sea Ray Sundancer 350 Coupe 2021?
For trailering, the Sea Ray 305 Sundancer 2012 has the edge at 863 lbs dry weight versus 18 792 lbs for the Sea Ray Sundancer 350 Coupe 2021. 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.
Which boat can handle a bigger outboard?
The Sea Ray Sundancer 350 Coupe 2021 is rated to a maximum of 350 hp, giving it the larger power ceiling. The Sea Ray 305 Sundancer 2012 tops out at 260 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Sea Ray 305 Sundancer 2012 is Coast Guard rated for 10 passengers, while the Sea Ray Sundancer 350 Coupe 2021 is certified for 10. 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.
Which boat is wider, and does it affect trailering?
The Sea Ray Sundancer 350 Coupe 2021 measures 137" wide, compared to 111" for the Sea Ray 305 Sundancer 2012. 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.
Which boat has the larger fuel tank — the Sea Ray 305 Sundancer 2012 or the Sea Ray Sundancer 350 Coupe 2021?
The Sea Ray Sundancer 350 Coupe 2021 has the bigger tank at 214 gallons, versus 1 gallons on the Sea Ray 305 Sundancer 2012. That 213-gallon difference translates to roughly 639–1065 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sea Ray 305 Sundancer 2012 and Sea Ray Sundancer 350 Coupe 2021 from the same manufacturer?
Yes — both the Sea Ray 305 Sundancer 2012 and the Sea Ray Sundancer 350 Coupe 2021 are built by Sea Ray. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
