The Carbon Grand Tourer
EON 35 combines high-performance marine engineering with the comfort and protection of a fully enclosed cabin. A pre-preg carbon/epoxy structure, twin-step deep-V hull and twin Mercury Racing propulsion form the performance platform.
Performance design, carbon detailing and bespoke material specification.
Marine engineering, systems integration and project execution.

Built for more than a short run.
Fuel capacity and onboard systems are specified for coastal cruising between ports, islands and anchorages.
Based on a 10 % fuel reserve. Final range is subject to configuration, conditions and sea-trial validation.
Performance
Engineered around speed, ride control and stability at sea.
Two configurations. One carbon platform.
Choose between the range-focused Grand Touring configuration and the higher-output Performance configuration.

All vessel-performance figures are EON objectives pending final engineering and validation; they are not propulsion-manufacturer claims.
Fuel-flow and range values are engineering estimates based on the current design specification and 900 L fuel capacity with a 10 % reserve.
Twin Mercury Racing V8 power.
EON 35 is specified with twin 8.2-litre supercharged Mercury Racing V8 engines, available in 600 hp and 700 hp configurations.
How EON 35 compares.
A typical 35-foot performance boat is open, moulded in GRP and designed to around 40 knots.

|---|---|---|
| Structure | GRP hull with carbon trim | Pre-preg carbon/epoxy |
| Layout | Open cockpit, T-top | Fully enclosed cabin |
| Target top speed | 38–45 kn | 57–63 kn |
| Power-to-weight | Approx. 120–180 hp/t | Approx. 233–257 hp/t |
| Ride control | Trim tabs | Humphree interceptors |
| Accommodation | Day boat | 2 + 2 berths, wet head, galley |
| Specification | Standard options list | Individually specified |
Category figures are indicative and not attributed to any manufacturer. EON 35 figures are preliminary design targets subject to validation.
Integrated around the driver and the boat.
Navigation, ride control, electrical management and onboard comfort systems are integrated into the EON 35 platform.
Electrochromic glazing+
Variable-tint laminated marine glazing controls solar load while maintaining panoramic visibility through the enclosed cabin.
Active ride control+
Humphree fast-response interceptors provide automatic trim and list control, calibrated to the hull during sea trials.
Docking assistance+
A 360-degree camera system improves visibility during docking and close-quarters manoeuvring.
Glass bridge+
Three anti-glare displays integrate navigation, radar, AIS, VHF/DSC, GNSS, autopilot and depth. Critical safety functions retain physical controls.
Electrical system+
A 48 V lithium hotel system of approximately 15 kWh supports onboard services. Independent 24 V circuits are provided for engine starting.
Lighting+
Integrated linear lighting provides general and ambient illumination, with dedicated night-mode lighting at the helm.
Climate and acoustic control+
HVAC, demisting, forced ventilation and targeted acoustic treatment are integrated throughout the passenger compartment.
Enclosed comfort at speed.
A protected helm and passenger area with accommodation for overnight use.
Specify the interior.
Three interior directions provide the starting point for each EON 35 build. Upholstery, carbon finish, metal detailing, stitching, lighting and graphics can then be configured for the individual boat.
Semi-aniline marine leather over multi-density foam, satin forged-carbon shells and dark-titanium hardware. Materials and finishes are specified per boat.
The object, observed.
