Cobalt R31 Surf Boats For Sale

The Cobalt R31 Surf is a 31-foot 5-inch surf boat built in Kansas and certified as a yacht, which means it carries no fixed maximum passenger count — capacity is whatever a captain can safely manage with a life jacket aboard for each person. It weighs 9,500 pounds, runs a beam of 9 feet 10 inches, and holds 160 gallons of fuel. Cobalt positions it for families who want to cruise to a sandbar or restaurant, tie up for the day, and still drop a board behind the boat for a surf session. Anyone shopping the R31 Surf for sale is looking at a large-platform surf boat rather than a dedicated tow-sports machine.

Power comes from twin Volvo Penta 380-horsepower forward-facing stern drives for a combined 760 horsepower. The forward-facing layout places the props up under the hull rather than trailing behind, which adds a margin of safety for swimmers and surfers. Despite being a twin stern-drive rather than an inboard V-drive, the R31 produces a surfable wave, and the hull generates enough speed to pull a wakeboarder wake-to-wake or even a slalom skier. For the cleanest wave, you want roughly 12 feet of water depth so it can fully shape up.

The helm runs Volvo's EVC (Electronic Vessel Control) system, fully drive-by-wire with no cables. A four-drive setup feeds joystick maneuverability that allows 360-degree spins, sideways crab-walking into a dock, and a dedicated docking mode that consolidates controls to the joystick. There's also a joystick-driving function that steers the boat by tilt with throttle feedback on the screen, no steering wheel required. Twin throttles can be collapsed to single-lever control. A glass cockpit with dual screens handles digital switching for the windlass, lighting, and pumps, plus addressable RGB lighting and the surf controls. The next-generation surf system offers four starter wave profiles from mellow to steep; each drive trims independently to tune the wave, and profiles can be saved or rewritten. The boat can be outfitted with Garmin radar and FLIR thermal vision for running big open water, and a Seakeeper gyro can be fitted to keep it level underway.

The deck layout is built around storage and lounging. The bow has 10 cup holders, wireless chargers and USB ports on both sides, an insulated cooler, a removable table, and a windlass anchor operable from the bow or helm. A prep galley sits in the cockpit, available with a charcuterie-board refrigerator alongside an oversized tilt-out trash can. The passenger seat is extra-wide with an adjustable bolster, swivels aft, and can be paired with an optional helm screen showing charts, engine data and stereo. Flooring options include Cobalt's soft-track non-skid, seagrass, and traditional teak.

A watersports closet, accessible from both the cockpit and bow, holds fold-up board racks and jacket storage and can be ordered with a head — toilet and sink. The static tower with hardtop carries a center tow point, an aft-facing camera, and a Roswell T2 three-position board rack. At the transom, adjustable rumble seats and a roughly 6-foot-wide lounge sit ahead of a full-beam swim platform, available with hydraulics and a flip step. An optional splash-and-stow inflatable mat tucks under a transom cushion, and an onboard air compressor and transom heat round out the options. Fit and finish through the compartments, latches and interfaces is a consistent strength. Configuration choices are extensive — gel coat, upholstery, tower style, and stereo speaker count and placement are all built to order at cobaltboats.com.
