Production Technology

Soft and elegant lines were key for the design. Wanted to make a pure sophisticated exterior which leads us to use similar color and tonnes of hull portholes and fashion plate glass. Therefore plain surface with 2 tones of same color were used. There are even no open hawseholes at bow area in order to keep the unity and harmony.

Design Challenge

Two main challanges in the creative and research period for Project Kai were the weight of the desired battery pack and the high temperature of the battery pack in electric mode.
We have planned to place the battery pack room between the amidship and the engine room, therefore the weight of the battery pack would not effect the main stability. About the possible high temperature, closed circuit water cooling system from seawater will be applied between all bulkeads and battery packs as well as between every individual battery one by one.

Research

The main research for the project was the eco-friendly navigation systems research. Instead of using generator activated electric azipods, we wanted to use the brand new Man Smart Hybrid engines that can allow the navigation in electric, diesel or both.

Inspiration

The very first idea was to make an eco-friendly gentelman's yacht that can dock most of the marinas and ports without restrictions in size. Owner privacy was also key which leads us to make a full enclosed deck with no crew transpassing, even in docking manoeuver. Other idea was to carry the tender on the deck in long journeys instead of towing them on water. Therefore we have decided to go with a 3deck yacht design with a descending aft deck that can lift and carry the tender.

Project Duration

The project started in Hamburg, Germany in November 2023 when we were in the process of establishing our Hamburg Branch Office and have been developed in Antalya and Marmaris, Turkey.

Operation Flow

With the new engine system, the yacht can decide different navigation options such as:
Zero-Emission Mode: No noise and vibration, zero emission
Diesel-Electric Mode: Low noise, vibration and emission
Crossover Mode: Very economical operation, Long range, Low Vibrations, Extended operating time before
service
Boost Mode: Combination of hybrid and zero-emission. %20 more power when compared to conventional system.
