Our take

What a buyer should know

A hand-built Dutch electric sloop

The Sluiper 21 is a 6.30 m electric sloop, hand-built by Jachtwerf Reeuwijk in the Netherlands — a classic open day boat for 9, made for the quiet inland water it is named for.

The numbers

A 4.4 kW Waterworld motor and a 13.6 kWh lithium battery drive it silently, at 950 kg. The yard publishes speed and range in km/h — 12 km/h top, 8 km/h cruise, 95 km range — so knots and nautical miles are left out here rather than converted. CE design category D, polyester hull. Price on request.

The builder

Jachtwerf Reeuwijk is a Dutch yard that builds its own electric sloop in-house. The Sluiper 21 is its single model, a hand-built boat sold direct from the yard.

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.
