PART ONE: A TIMELESS ICON WITH DUAL PROPULSION OPTIONS

For collectors and connoisseurs of pure Italian nautical art, we present the Riva Ariston "Naïade" (Hull Number 355), historically recognized as the favorite model of engineer Carlo Riva himself. Built entirely from premium mahogany wood on the shores of Lake Iseo, this masterpiece boasts a transparent ownership history with only two owners over the last 25 years.

The true uniqueness of this offer lies in its extraordinary technical versatility. The boat is currently configured as the only proven specimen on the market converted to 100% high-performance electric propulsion by Lanéva Boats, offering silent, zero-emission navigation with no fuel costs—ideal for accessing lakes and marine protected areas.

However, to satisfy the demands of traditional purists, the vessel is offered with a clear dual purchase option:

100% Electric Configuration: Ready for immediate use with an advanced industrial powertrain and a latest-generation battery pack. 

Thermal Engine Configuration (Retrofit): A "Thermal Re-powering package" can be requested to reinstall a classic internal combustion engine (V8) prior to delivery. 

The unit has just completed a deep, photographically documented professional restoration between January and April 2026. Interventions included full stuffing-box replacement, shaft-line refitting, full inspection and repainting of the interior bilge and underwater body, transom repairs, and the refurbishment of the iconic turquoise and white decorative stripe matching the original upholstery.
