Sea Ray's "SLX" designation signals that the builder has put "luxury" styling and up-graded materials into this model to raise her above the standard offerings on the market. Her helm instrument console is particularly impressive, and we like her slightly retro centerline cockpit access from the stern. But perhaps the boat's most important attribute, is her "Quiet Ride" technology. The 250 SLX at hr "best cruise" setting of 3500 RPMs has a 76 dbA sound level according to our meter. This is extremely quiet by any standard.
