Cutting edge hybrid battery propulsion technology with fully custom exterior

These two customized yachts may look different, but are in fact the same design, with an exterior customized according to the Owner’s preferences. They were very keen to give a distinctive look to the vessel and several configurations of superstructures were developed with particular focus on personal expression.

The yacht is designed to be operated by only 2 persons in keeping with trends towards short handed operation, and this is also reflected in the luxurious accommodation for up to 12 persons which can be any mix of crew and passengers.

The reinforced steel hulls and aluminium superstructures will allow the yachts to navigate the Baltic and North Atlantic all year round.

These designs will be available for repeat constructions of similar yachts.

The hybrid propulsion system consists of diesel main engines and back-up batteries. The batteries allow the yacht to slip quietly into a busy marina, manoeuvre and berth without any harmful emissions or engine noise. As an additional feature in order to save fuel, when cruising at lower speed, the hybrid system supports operating with one main engine only. In this propulsion mode, two shafts and propellers continuously propel the yacht.


Founder and former Owners of communication technology company Thrane & Thrane A/S, Mr. Lars Thrane and Mr. Per Thrane, have entrusted the design development of two cutting edge technology Explorer Type Motor Yachts to KNUD E. HANSEN.

KNUD E. HANSEN has developed the Concept and Basic Design as well as specifications in close collaboration with the experienced owners. Furthermore, flag state discussions, shipyard evaluation and contract discussions were undertaken by KNUD E. HANSEN. 


The two Yachts are designed with identical diesel hybrid CPP (Controllable Pitch Propeller) propulsion system.

A revolutionary diesel electric system – HyPS, developed by a sister company to Holland Jachtbouw, will be integrated in both yachts.

The system-technology connects the propulsion Permanent Magnet synchronous machines to an electrical DC-BUS system in combination with a variable speed generator set, a heavy duty light weight Li-ion battery system and shore power supply lines. Furthermore, the main (electric) consumers are connected on the power-consumer side of the DC-BUS system.
