The Sea Ray 390's helm design incorporates many of the features Sea Ray has developed to consolidate and simplify vessel operation. The automotive-inspired console, designed to accommodate the Sea Ray Navigator system, leaves everything within reach. The system's 10.4-inch, sunlight-viewable touch-screen LCD conveys charting and navigation information in a user-friendly format. The 390 is also equipped with Mercury Marine's SmartCraft electronic information system. The helm-mounted control head coordinates and displays data from a number of sources. On our test boat, data included engine vitals, fuel burn, range, navigation information, depth, and air and seawater temperature.
