Sea Ray 300 Sundeck 2013 vs Sea Ray 390 Sedan Bridge 2010 — Same Brand, Different Boat

Matching a deep vee Sea Ray 300 Sundeck 2013 against a semi displacement Sea Ray 390 Sedan Bridge 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 390 Sedan Bridge 2010 measures 38,3 feet overall (2010), giving it roughly 8,8 additional feet of deck space compared to the Sea Ray 300 Sundeck 2013 at 29,5 feet (2013). Weight tells a clearer story for trailering families: the Sea Ray 300 Sundeck 2013 tips the scales at 6 044 lbs — 6 022 lbs more than the Sea Ray 390 Sedan Bridge 2010 at 22 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 370 hp, the Sea Ray 390 Sedan Bridge 2010 has a 70-hp advantage over the Sea Ray 300 Sundeck 2013'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 2013 carries 93 gallons versus 3 gallons in the Sea Ray 390 Sedan Bridge 2010. 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 390 Sedan Bridge 2010 is rated for 11 passengers, while the Sea Ray 300 Sundeck 2013 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 390 Sedan Bridge 2010 could be the deciding factor.

Bottom line: Choose the Sea Ray 390 Sedan Bridge 2010 if your priority is putting more people on the water — it handles 11 passengers and at 38,3 ft it has the deck room to back that rating up comfortably. The Sea Ray 300 Sundeck 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.

Sea Ray 300 Sundeck 2013 vs Sea Ray 390 Sedan Bridge 2010 — Common Questions

Which is the larger boat — the Sea Ray 300 Sundeck 2013 or the Sea Ray 390 Sedan Bridge 2010?
The Sea Ray 390 Sedan Bridge 2010 is the longer of the two at 38,3 feet overall. The Sea Ray 300 Sundeck 2013 comes in at 29,5 feet, making it roughly 8,8 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray 300 Sundeck 2013 or the Sea Ray 390 Sedan Bridge 2010?
For trailering, the Sea Ray 390 Sedan Bridge 2010 has the edge at 22 lbs dry weight versus 6 044 lbs for the Sea Ray 300 Sundeck 2013. 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 390 Sedan Bridge 2010 is rated to a maximum of 370 hp, giving it the larger power ceiling. The Sea Ray 300 Sundeck 2013 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 Sundeck 2013 is Coast Guard rated for 8 passengers, while the Sea Ray 390 Sedan Bridge 2010 is certified for 11. 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 390 Sedan Bridge 2010 measures 156" wide, compared to 109" for the Sea Ray 300 Sundeck 2013. 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 Sundeck 2013 or the Sea Ray 390 Sedan Bridge 2010?
The Sea Ray 300 Sundeck 2013 has the bigger tank at 93 gallons, versus 3 gallons on the Sea Ray 390 Sedan Bridge 2010. That 90-gallon difference translates to roughly 270–450 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sea Ray 300 Sundeck 2013 and Sea Ray 390 Sedan Bridge 2010 from the same manufacturer?
Yes — both the Sea Ray 300 Sundeck 2013 and the Sea Ray 390 Sedan Bridge 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.
