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.
