From €41,000
Draft 0.5m. Low-power/low-speed configuration: 8kW motor, 21kWh battery (AGM or lithium option), top speed ~13km/h (~7 knots) — positioned as a leisurely, displacement-speed model rather than a performance boat, unlike the similarly-sized Magic 640.

What a buyer should know
A displacement boat, and unapologetic about it
The Delta 600 is the calm end of Marian's small-boat range. An 8 kW motor and a 21 kWh pack give roughly 7 knots — walking pace on the water — and that combination is the point rather than a limitation. A small motor drawing from a pack of this size will run for a long afternoon at cruising speed, which is exactly what a lake boat needs. Draft is 0.5 m, so shallow shorelines and reed-lined bays are open to it.
Who should look elsewhere
Anyone who wants to tow a skier, tender a larger yacht at pace, or cross open water against wind and chop. At 7 knots the Delta cannot outrun weather, and it is not a coastal boat.
The interesting comparison is in-house: the Magic 640 is barely larger yet carries 100 kW and 84 kWh for €51,600, against the Delta's €41,000. That roughly €10,600 gap buys a completely different character. Choose the Delta if silence, endurance and low running cost are the priorities; choose the Magic if speed ever will be. Note too that the battery is offered as AGM or lithium — establish which chemistry the quoted price assumes, because the difference in weight, life and cost is substantial.
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.
