First Inveni 18m leaves the blocks

Ship & Boat International: eNews May/June 2019



Dutch newcomer Sichterman, which describes itself as a "boutique yacht builder", has overseen its first newbuild launch, in the form of the Inveni 18m motor yacht.


The vessel, which was designed by compatriot naval architect Cor D. Rover and built by partner group Workumer Yachtservice, was ordered by Ruud van Hilst, a former competitive sailor. The yacht type measures 18m x 5.15m, is designed to displace 31.5tonnes and can accommodate up to six passengers, with overnight berths provided for four persons.


Sichterman was established earlier this year with the stated aim of producing all-aluminium yachts in the 15-26m range. The company's yacht output will feature technology such as the Hull Vane and Fast Displacement Hull Form (FDHF) concepts, both developed by Van Oossanen Naval Architects. The FDHF is intended to enable higher transit speeds while simultaneously keeping a check on hydrodynamic resistance, and the Hull Vane functions as a hydrofoil located below the stern, which is intended to enhance seakeeping while cutting fuel consumption (see Ship & Boat International November/December 2017, pages 44-46).


Power is provided by two Cummins diesel engines, each rated just over 410kW, and these enable a cruising speed of 18knots and a top speed of 23knots. Other features include a 1,000litre-capacity water tank, a vertical bow, the aforementioned Hull Vane and FDHF units and Seakeeper’s anti-roll solution. Using the Van Oossanen kit, the yacht is expected to realise a fuel saving of 20%, Sichterman CEO Bart Rehe comments.
