Detailed Evaluation & Buyer Recommendation
Sea Ray 420 Sedan Bridge 2005 vs Sea Ray Express Cruiser 340 1988 — Same Brand, Different Boat
The Sea Ray 420 Sedan Bridge 2005 vs Sea Ray Express Cruiser 340 1988 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 420 Sedan Bridge 2005 measures 45,0 feet overall (2005), giving it roughly 11,0 additional feet of deck space compared to the Sea Ray Express Cruiser 340 1988 at 34,0 feet (1988). Weight tells a clearer story for trailering families: the Sea Ray Express Cruiser 340 1988 tips the scales at 10 100 lbs — 9 815 lbs less than the Sea Ray 420 Sedan Bridge 2005 at 285 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 Sea Ray Express Cruiser 340 1988 tops out at 340 hp. Engine specs for the Sea Ray 420 Sedan Bridge 2005 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Sea Ray 420 Sedan Bridge 2005 carries 35 gallons versus 25 gallons in the Sea Ray Express Cruiser 340 1988. 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 420 Sedan Bridge 2005 is rated for 13 passengers, while the Sea Ray Express Cruiser 340 1988 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 420 Sedan Bridge 2005 could be the deciding factor.
Bottom line: Choose the Sea Ray 420 Sedan Bridge 2005 if your priority is putting more people on the water — it handles 13 passengers and at 45,0 ft it has the deck room to back that rating up comfortably. The Sea Ray Express Cruiser 340 1988 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
