2018 Cobalt R30 R30 As one of the larger bowriders in the Cobalt lineup, the R30 still displays the maneuverability and operation youd expect from a company known for its legendary ride. Designed with touches of comfort, style, and luxury throughout, the R30 features a hydraulic swim step that lowers into the water for easy access, a head compartment that doubles as a changing room and a helm equipped with Garmin screens all to make your day on the water a memorable one. This boat does not include a trailer but one is available if needed.
