"Power" package. Figures published by Silennis at https://sites.google.com/silennis.com/english/our-boats/s010: 8 km/h (4.3 kn) max with 1 h autonomy, 5.4 km/h (3.0 kn) cruise with 5 h autonomy, calm sea, clean hull, max 2 people. Range shown is those two published figures multiplied (3.0 kn for 5 h), not a builder-stated distance. Price 16,613 EUR excluding VAT, quoted by Jose Alegria 2026-07-29.

Figures published by Silennis at https://sites.google.com/silennis.com/english/our-boats/s010: 10 km/h (5.4 kn) max with 1 h 10 min autonomy, 7.5 km/h (4.1 kn) cruise with 4 h 30 min autonomy. Range shown is those two published figures multiplied, not a builder-stated distance. No price published for this capacity — the 19,971 EUR quote covers the 4.8 kWh package instead (confirmed 2026-07-30).

"Premium" package with the larger battery. Jose Alegria confirmed on 2026-07-30 that 19,971 EUR excluding VAT is the price for this 4.8 kWh configuration, and that the autonomy table sent on 2026-07-29 was the 3.4 kWh one in error. Speeds and autonomy are deliberately empty: the figures we hold belong to the 3.4 kWh pack and do not describe this one.
What a buyer should know
Who it suits
The Silennis S010 is the smallest boat in this catalogue by a wide margin, and it is not a yacht at all: 3.95 m by 1.85 m, half a metre of draft and 385 kg, it is a trailerable runabout and tender built by a Spanish yard for sheltered water. That footprint is the point. It fits a standard parking space, launches from a slipway without a crane, and its length and output together keep it below the licence threshold in several European jurisdictions. Silennis drew it for rental operators, and it suits the same work privately — lakes, canals, and shore-boat duty off a larger yacht. It is rated for seven people in CE category D and four in category C. Anyone thinking about open coastal water should look elsewhere.
What the numbers mean
The hull comes with a choice of two ePropulsion outboards, and the difference between them is smaller than the price gap suggests. The Power package — a 1 kW Spirit 1.0 Evo with a 1.28 kWh battery — cruises at 3 knots for five hours and tops out at 4.3 knots. The Premium package — a 3 kW Navy 3.0 with 3.4 kWh — cruises at 4.1 knots for four and a half hours and tops out at 5.4 knots. Three times the motor and nearly three times the battery buy about one extra knot and half an hour less endurance, which is a fair illustration of what speed costs an electric boat. Read the autonomy figures carefully, though: Silennis states them for calm water, a clean hull and two people aboard, not the seven the boat is certified to carry.
Caveats
The entry price is €16,613 excluding VAT, which is real money for a 3.95 m boat and worth weighing against a petrol outboard on a comparable hull. The Premium package is quoted at €19,971 excluding VAT, but Silennis has given two different capacities for it — 3.4 kWh on its specification page and 4.8 kWh alongside that price — so no price is shown against that configuration here until the yard confirms which battery it covers. The structural choice worth understanding is the outboard itself, which is deliberate: it can be swapped by any dealer, the propeller lifts clear of the water at the mooring, and ePropulsion, Torqeedo and Mercury all have service networks behind them. Silennis will fit other motor and battery combinations up to 3 or 4 kW, and there is room for further batteries in the central locker, so the two published packages are a starting point rather than the whole range.
