Matching a deep vee Sea Ray 340 Sundancer 2008 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.

On paper these two are close siblings in the size department — Sea Ray 340 Sundancer 2008 at 37,0 ft versus Sea Ray 390 Sedan Bridge 2010 at 38,3 ft. Weight tells a clearer story for trailering families: the Sea Ray 340 Sundancer 2008 tips the scales at 155 lbs — 133 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.

Both boats share a closely matched power ceiling — 375 hp for the Sea Ray 340 Sundancer 2008 and 370 hp for the Sea Ray 390 Sedan Bridge 2010. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Sea Ray 340 Sundancer 2008 carries 225 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.

Both boats are rated for 11 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
