The SC in R25SC stands for Sport Cockpit. The SC cockpit (aft deck) is 25% larger than our original R25 giving it nearly 50 sq ft of aft deck space. The larger cockpit also lends itself to more above and below deck storage and makes for easy access to the standard Yanmar 4BY2 150 HP Yanmar diesel. The Yanmar engine is located entirely outside of the cabin making for smooth, quiet cruising. The standard bow and stern thruster provide for excellent maneuverability around the dock and the 8′ 6″ beam allows the boat to be easily trailered.
