Sea Ray 300 Select EX 2010 vs Sea Ray 300 Sundeck 2012 — Same Brand, Different Boat

Matching a modified vee Sea Ray 300 Select EX 2010 against a deep vee Sea Ray 300 Sundeck 2012 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department — Sea Ray 300 Select EX 2010 at 29,5 ft versus Sea Ray 300 Sundeck 2012 at 29,5 ft. Weight tells a clearer story for trailering families: the Sea Ray 300 Sundeck 2012 tips the scales at 6 044 lbs — 5 967 lbs less than the Sea Ray 300 Select EX 2010 at 77 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 430 hp, the Sea Ray 300 Sundeck 2012 has a 130-hp advantage over the Sea Ray 300 Select EX 2010's 300-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 300 Sundeck 2012 carries 93 gallons versus 13 gallons in the Sea Ray 300 Select EX 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 8 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 300 Sundeck 2012 and its 430-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Sea Ray 300 Select EX 2010 with its 300-hp rating is the more economical daily driver.

Sea Ray 300 Select EX 2010 vs Sea Ray 300 Sundeck 2012 — Common Questions

Which is the larger boat — the Sea Ray 300 Select EX 2010 or the Sea Ray 300 Sundeck 2012?
The Sea Ray 300 Sundeck 2012 is the longer of the two at 29,5 feet overall. The Sea Ray 300 Select EX 2010 comes in at 29,5 feet, making it roughly 0,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray 300 Select EX 2010 or the Sea Ray 300 Sundeck 2012?
For trailering, the Sea Ray 300 Select EX 2010 has the edge at 77 lbs dry weight versus 6 044 lbs for the Sea Ray 300 Sundeck 2012. 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 300 Sundeck 2012 is rated to a maximum of 430 hp, giving it the larger power ceiling. The Sea Ray 300 Select EX 2010 tops out at 300 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 300 Select EX 2010 is Coast Guard rated for 8 passengers, while the Sea Ray 300 Sundeck 2012 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.
Which boat is wider, and does it affect trailering?
The Sea Ray 300 Select EX 2010 measures 116" wide, compared to 109" for the Sea Ray 300 Sundeck 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 300 Select EX 2010 or the Sea Ray 300 Sundeck 2012?
The Sea Ray 300 Sundeck 2012 has the bigger tank at 93 gallons, versus 13 gallons on the Sea Ray 300 Select EX 2010. That 80-gallon difference translates to roughly 240–400 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sea Ray 300 Select EX 2010 and Sea Ray 300 Sundeck 2012 from the same manufacturer?
Yes — both the Sea Ray 300 Select EX 2010 and the Sea Ray 300 Sundeck 2012 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.
