Both the Sea Ray 270 Select EX 2009 and the Sea Ray 290 Sun Sport 2008 are modified-V designs, both built in fibreglass, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department - Sea Ray 270 Select EX 2009 at 28,5 ft versus Sea Ray 290 Sun Sport 2008 at 29,0 ft. Weight tells a clearer story for trailering families: the Sea Ray 290 Sun Sport 2008 tips the scales at 8 300 lbs - 2 745 lbs less than the Sea Ray 270 Select EX 2009 at 5 555 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 270 Select EX 2009 has a 50-hp advantage over the Sea Ray 290 Sun Sport 2008's 375-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 290 Sun Sport 2008 carries 130 gallons versus 91 gallons in the Sea Ray 270 Select EX 2009. 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 290 Sun Sport 2008 is rated for 12 passengers, while the Sea Ray 270 Select EX 2009 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 290 Sun Sport 2008 could be the deciding factor.
