Matching a modified vee Sea Ray 300 Sundeck 2010 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 2010 at 29,5 feet (2010). Weight tells a clearer story for trailering families: the Sea Ray 300 Sundeck 2010 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 425 hp, the Sea Ray 300 Sundeck 2010 has a 55-hp advantage over the Sea Ray 390 Sedan Bridge 2010'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 300 Sundeck 2010 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 2010 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.
