What a buyer should know
The flagship, and what the extra money buys
At 24.3 m with a 429 kWh pack, twin 340 kW motors and up to roughly 90 m² of solar, the Silent 80 Tri-Deck is the top of the range and priced accordingly at €5.51m — around double the Silent 60 for about a third more length. What you are paying for is volume, the Marco Casali/MICAD styling, and above all solar area: nearly doubling the panel coverage is what makes a boat this size credible as a largely self-charging platform.
The 18-knot top speed is the specification that most separates it from its siblings. Where the Silent 60 is published at 8 knots and is unambiguously a displacement passage-maker, the 80 has genuine reserve — useful for repositioning, weather avoidance, and keeping a charter schedule. That performance headroom is a real functional difference, not a trim level.
Caveats worth stating plainly
Diesel generators are part of the specification as range extenders, so this is not a fossil-free boat in practice; it is a boat that can run on solar much of the time and falls back on fuel when it cannot. At this size expect professional crew, superyacht-tier berthing and refit costs. And as with the rest of the range, confirm build slots and warranty arrangements with the yard directly given Silent Yachts' recent commercial history.
Written from the builder’s published specifications and the wider market, not from testing the boat ourselves. Always confirm figures with the manufacturer before committing.
