Sea Ray 450 Sedan Bridge 2013 vs Sea Ray Express Cruiser 390 1990 — Same Brand, Different Boat

The Sea Ray 450 Sedan Bridge 2013 vs Sea Ray Express Cruiser 390 1990 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.

Size is the most obvious dividing line here. The Sea Ray 450 Sedan Bridge 2013 measures 45,6 feet overall (2013), giving it roughly 3,6 additional feet of deck space compared to the Sea Ray Express Cruiser 390 1990 at 42,0 feet (1990). Weight tells a clearer story for trailering families: the Sea Ray 450 Sedan Bridge 2013 tips the scales at 36 602 lbs — 20 202 lbs more than the Sea Ray Express Cruiser 390 1990 at 16 400 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 480 hp, the Sea Ray 450 Sedan Bridge 2013 has a 110-hp advantage over the Sea Ray Express Cruiser 390 1990's 370-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 2013 carries 375 gallons versus 3 gallons in the Sea Ray Express Cruiser 390 1990. 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 2013 is rated for 13 passengers, while the Sea Ray Express Cruiser 390 1990 caps at 12. 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 2013 could be the deciding factor.

Bottom line: Choose the Sea Ray 450 Sedan Bridge 2013 if your priority is putting more people on the water — it handles 13 passengers and at 45,6 ft it has the deck room to back that rating up comfortably. The Sea Ray Express Cruiser 390 1990 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.

Sea Ray 450 Sedan Bridge 2013 vs Sea Ray Express Cruiser 390 1990 — Common Questions

Which is the larger boat — the Sea Ray 450 Sedan Bridge 2013 or the Sea Ray Express Cruiser 390 1990?
The Sea Ray 450 Sedan Bridge 2013 is the longer of the two at 45,6 feet overall. The Sea Ray Express Cruiser 390 1990 comes in at 42,0 feet, making it roughly 3,6 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray 450 Sedan Bridge 2013 or the Sea Ray Express Cruiser 390 1990?
For trailering, the Sea Ray Express Cruiser 390 1990 has the edge at 16 400 lbs dry weight versus 36 602 lbs for the Sea Ray 450 Sedan Bridge 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 450 Sedan Bridge 2013 is rated to a maximum of 480 hp, giving it the larger power ceiling. The Sea Ray Express Cruiser 390 1990 tops out at 370 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 2013 is Coast Guard rated for 13 passengers, while the Sea Ray Express Cruiser 390 1990 is certified for 12. 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 2013 measures 173" wide, compared to 157" for the Sea Ray Express Cruiser 390 1990. 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 2013 or the Sea Ray Express Cruiser 390 1990?
The Sea Ray 450 Sedan Bridge 2013 has the bigger tank at 375 gallons, versus 3 gallons on the Sea Ray Express Cruiser 390 1990. 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 2013 and Sea Ray Express Cruiser 390 1990 from the same manufacturer?
Yes — both the Sea Ray 450 Sedan Bridge 2013 and the Sea Ray Express Cruiser 390 1990 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.
