The Lanéva Vesper is a 7.9-metre premium electric dayboat developed around a dedicated electric hull rather than converted from a combustion platform. Its single-shaft 140 kW drive draws from a 126 kWh DNV-certified lithium-ion NMC battery, and the cockpit carries up to eight people. Lanéva emphasizes bio-based and recyclable materials, including flax fibre, basalt fibre, cork and marine synthetic upholstery. A telemetry and digital-switching system monitors temperature, voltage, current, charging and other powertrain data locally or remotely. The current Vesper 001 sale page describes a 2019 boat refitted in 2023, while other Lanéva pages discuss the Vesper platform more broadly and publish slightly different speed, range and price figures. Buyers should therefore separate the specific used/refitted vessel from any new custom build proposal.
