Cobalt R4 Surf: w/20 Rider Profiles

The R4 Surf measures 24’3” (7.39 m) with an 8’6” (2.59 m) and she’s rated to carry 13 passengers.

Cobalt Boats has expanded its Surf series with the new R4 Surf, a 24’3” (7.39 m) wake surfing boat. She’s powered by a Volvo Penta forward-facing stern drive and has wake-shaping appendages, a ballast system and Cobalt Custom-Wave Technology that allows for up to 20 savable rider profiles.




Premium Foundation




Like all boats from the Neodesha, KS, based manufacturer, the R4 Surf has top-shelf amenities and fit and finish. In addition to the SurfGate technology that was patented by Cobalt parent Malibu Boats, the standard-equipment list includes a six-speaker audio system linked to a Bluetooth stereo with an iPod/USB/MP3 port, a Garmin glass cockpit with dual screens, convertible seating and more.




Starting at the bow, the R4 Surf has deep seating with backrests on the front of each console. There’s storage under each bottom cushion plus an anchor locker in the forepeak. Moving aft into the cockpit, the port console has a locking glovebox with additional space below. The backrest can be set for conventional forward-facing travel or converted for observing the action going on behind the boat.


The R4 Surf has versatile seating throughout and good depth to provide a secure ride.


To starboard, the helm has a captain’s seat with a flip bolster and all navigation, engine and surf data are displayed on twin 8” (20.32 cm) Garmin multifunction displays. An upgrade to 10” (25.4 cm) screens is an available option. The helm also has illuminated sealed accessory switches, and a wireless cell-phone charger. Taking a closer look at the screens, Cobalt’s Custom Wave Technology lets a driver program up to 20 rider profiles that can be edited, removed or renamed by following screen prompts. The driver can switch from left to right waves when underway and adjust trim, speed and more.


The Cobalt surf system lets the driver control the ballast, wake direction and speed with a touchscreen.


Versatile Cockpit




The port-side bottom cushion is hinted and opens to access storage with a wastebasket, brackets for the ski-tow pylon and fire extinguisher and access to the battery switch and circuit breakers.




The aft seat can be set up in three positions, forward or rear facing and a chaise-lounge position. An owner can opt for the aft-facing rumble seat and upgrade from the standard swim platform to the E-platform that can be lowered into the water with the push of a button.


The cockpit places a premium on space and utility and an owner can choose among fixed mat or removable carpet or seagrass mat.


Open the engine compartment to check on the Volvo Penta V-8 engine available in power ratings up to 430 hp and the ballast pumps.




The wake surfing tower is made in-house and can fold down to get under a bridge or for storage in a rack or garage. It comes standard with Roswell Elite racks and upgrades to other choices are available.
