Sea Ray 450 Sedan Bridge 2012 vs Sea Ray Sedan Bridge 390 2010 — Same Brand, Different Boat

The Sea Ray 450 Sedan Bridge 2012 vs Sea Ray Sedan Bridge 390 2010 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.

The power gap is worth calling out. Rated to 600 hp, the Sea Ray 450 Sedan Bridge 2012 has a 220-hp advantage over the Sea Ray Sedan Bridge 390 2010's 380-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 450 Sedan Bridge 2012 carries 375 gallons versus 3 gallons in the Sea Ray Sedan Bridge 390 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 450 Sedan Bridge 2012 is rated for 13 passengers, while the Sea Ray Sedan Bridge 390 2010 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 450 Sedan Bridge 2012 could be the deciding factor.

Bottom line: Choose the Sea Ray 450 Sedan Bridge 2012 if your priority is putting more people on the water — it handles 13 passengers and at 45,5 ft it has the deck room to back that rating up comfortably. The Sea Ray Sedan Bridge 390 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 11 that costs less to run day-to-day.

Sea Ray 450 Sedan Bridge 2012 vs Sea Ray Sedan Bridge 390 2010 — Common Questions

Which is the larger boat — the Sea Ray 450 Sedan Bridge 2012 or the Sea Ray Sedan Bridge 390 2010?
The Sea Ray 450 Sedan Bridge 2012 is the longer of the two at 45,5 feet overall. The Sea Ray Sedan Bridge 390 2010 comes in at 39,0 feet, making it roughly 6,5 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The Sea Ray 450 Sedan Bridge 2012 is rated to a maximum of 600 hp, giving it the larger power ceiling. The Sea Ray Sedan Bridge 390 2010 tops out at 380 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 450 Sedan Bridge 2012 is Coast Guard rated for 13 passengers, while the Sea Ray Sedan Bridge 390 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 450 Sedan Bridge 2012 measures 173" wide, compared to 156" for the Sea Ray Sedan Bridge 390 2010. 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 450 Sedan Bridge 2012 or the Sea Ray Sedan Bridge 390 2010?
The Sea Ray 450 Sedan Bridge 2012 has the bigger tank at 375 gallons, versus 3 gallons on the Sea Ray Sedan Bridge 390 2010. That 372-gallon difference translates to roughly 1116–1860 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sea Ray 450 Sedan Bridge 2012 and Sea Ray Sedan Bridge 390 2010 from the same manufacturer?
Yes — both the Sea Ray 450 Sedan Bridge 2012 and the Sea Ray Sedan Bridge 390 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.
