What a buyer should know
A tender, sized honestly
The ST 330 Classic is a 3.35-metre electric jet tender — a boat for the short hop from a mooring or a larger yacht to the shore, not a day cruiser. 6 seats on a 170–190 kg hull, a maximum load of 450 kg, and a 1.65 m beam that stows on a superyacht’s foredeck or a small trailer. Judge it as a tender and it is well-judged; ask it to be a runabout and its 10-mile range will say otherwise.
The numbers
A ZeroJet 48-volt waterjet does the work — 15 kW, or 20 hp — fed by a 5 kWh battery. That returns 20 knots flat out and an 8–12 knot cruise good for about 10 nautical miles, or 1.5 hours on the water. Charging climbs from 20 to 80 percent in roughly 90 minutes, and to full in about 2.5 hours from a domestic outlet. The battery brand is not published, and there is no fast-charge figure; the range is a tender’s range, honestly stated.
The builder
SPARK is a young Latvian yard in Riga that moulds its own carbon and glass-fibre hull and buys in the proven ZeroJet drivetrain — a supplier relationship it shares with several other builders, not a rebadged boat. The hull and the composite work are its own, drawn from a team with a background in Olympic watersport structures. From €38,000 before VAT, it is a premium price for a compact tender, matched by carbon construction rather than a bare glass-fibre shell.
