The Helm & Cockpit — Command and Control
The R35’s helm is the nerve centre of this exceptional boat. A dual Garmin 8610 Glass Cockpit display provides high-resolution navigation, instrumentation and networking at your fingertips, giving the Captain complete confidence in any conditions. The ergonomic helm seat is extra-wide with electric adjustment, paired with a premium black leather and stainless-steel steering wheel and a gloss-black dash console with stainless-steel switches throughout.
For passengers, the new optional Helm Watch system serves as a secondary command centre, offering direct access to charts and cabin controls from the forward cockpit. So everyone on board can be part of the journey. The cockpit itself is expansive, measuring 2.74 metres wide, with Varadense Comfort seating, a hideaway dinette table and the option to add Cobalt’s signature AutoDeploy Galley. A pop-up galley with sink, microwave and optional electric grill that rises from beneath a bench seat at the touch of a button.
The Cabin — Luxury Below Deck
Step below into a cabin that rivals a premium yacht. The R35’s mid-cabin is simultaneously snug and spacious, featuring a full beam-width queen-sized gel memory foam mattress that converts from a generous sofa. The port-side head doubles as a private shower, complete with a VacuFlush system and dedicated sink console, while the cabin comes standard with skylight windows that flood the space with natural light.
Optional cabin upgrades include a 22-inch smart TV, LED interior accent lighting in RGB, custom wood interior trim and teak or Sea Grass flooring. With USB-C charging stations, wireless phone chargers and weighted throw pillows available, the cabin aboard this Cobalt boat is designed for comfort, whether you’re anchored for an afternoon or staying overnight.

- Hand-laid fibreglass at keel

Customisation — Make It Yours
One of the defining features of owning a new Cobalt R35 is the ability to personalise every detail. From stainless steel bow scuff plates, engine vents and windshield braces to custom-stitched helm eyebrows and colour-accented hard top headliners, the R35 offers an extensive menu of interior and exterior options.
Tailor your cockpit with options like teak flooring, Sof-Trac matting, a cockpit refrigerator/freezer with 90-litre capacity or the oversized solid teak dinette table with stainless steel support. On the exterior, select from a hydraulic swim platform with flip-down step, underwater lighting, teak swim platform accents, a cockpit boarding door for effortless entry and Cobalt’s Splash & Stow inflatable island or mat system for on-water leisure.
Premium sound options include the Harman Kardon Platinum system with hard top speakers, while a Garmin Fantom radar, FLIR thermal vision camera and VHF radio are available for those who venture further afield. Every custom choice is backed by Cobalt’s 10/5/3-year warranty protection. A standard commitment to quality that few boat manufacturers can match.
Surf, Leisure & On-Water Living
The R35 platform isn’t just for cruising. With Cobalt Boats now offering the R35 Surf variant powered by Volvo Penta Forward Drive, the R35 hull also serves as the foundation for world-class surf wave technology, making it one of the most versatile luxury boats on the market. For leisure on the water, the bow features walk-through access, an ice chest and an optional bow shade sail, while the transom offers a premium sound system, a hot and cold shower and the patented Cobalt swim step for easy water access.
Whether you’re hosting a day on the harbour, exploring a new coastline or setting up the perfect surf wave, the Cobalt R35 delivers an on-water experience that simply cannot be matched.
