Sea Ray 210 SLX® 2012 vs Sea Ray 300 Select EX 2010 — Same Brand, Different Boat

Matching a deep vee Sea Ray 210 SLX® 2012 against a modified vee Sea Ray 300 Select EX 2010 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.

Size is the most obvious dividing line here. The Sea Ray 300 Select EX 2010 measures 29,5 feet overall (2010), giving it roughly 8,5 additional feet of deck space compared to the Sea Ray 210 SLX® 2012 at 21,0 feet (2012). Weight tells a clearer story for trailering families: the Sea Ray 210 SLX® 2012 tips the scales at 408 lbs — 331 lbs more 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.

Both boats share a closely matched power ceiling — 300 hp for the Sea Ray 210 SLX® 2012 and 300 hp for the Sea Ray 300 Select EX 2010. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Sea Ray 300 Select EX 2010 carries 13 gallons versus 4 gallons in the Sea Ray 210 SLX® 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 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: The Sea Ray 300 Select EX 2010 at 29,5 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sea Ray 210 SLX® 2012 at 21,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.

Sea Ray 210 SLX® 2012 vs Sea Ray 300 Select EX 2010 — Common Questions

Which is the larger boat — the Sea Ray 210 SLX® 2012 or the Sea Ray 300 Select EX 2010?
The Sea Ray 300 Select EX 2010 is the longer of the two at 29,5 feet overall. The Sea Ray 210 SLX® 2012 comes in at 21,0 feet, making it roughly 8,5 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray 210 SLX® 2012 or the Sea Ray 300 Select EX 2010?
For trailering, the Sea Ray 300 Select EX 2010 has the edge at 77 lbs dry weight versus 408 lbs for the Sea Ray 210 SLX® 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.
How many people can each boat hold?
The Sea Ray 210 SLX® 2012 is Coast Guard rated for 8 passengers, while the Sea Ray 300 Select EX 2010 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 102" for the Sea Ray 210 SLX® 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 210 SLX® 2012 or the Sea Ray 300 Select EX 2010?
The Sea Ray 300 Select EX 2010 has the bigger tank at 13 gallons, versus 4 gallons on the Sea Ray 210 SLX® 2012. That 9-gallon difference translates to roughly 27–45 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sea Ray 210 SLX® 2012 and Sea Ray 300 Select EX 2010 from the same manufacturer?
Yes — both the Sea Ray 210 SLX® 2012 and the Sea Ray 300 Select EX 2010 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.
