DESIGN NAME: Libellula
PRIMARY FUNCTION: Sail Yacht
INSPIRATION: The sail yacht Libellula was designed with inspiration from nature. Dragonfly body lines and wing structure are the main starting point of the design. One of the most striking features of dragonflies is their agile flight. With their long, slender bodies and four delicate, transparent wings, they are incredibly maneuverable in the air.
UNIQUE PROPERTIES / PROJECT DESCRIPTION: Libellula has 50m lenght and 7.9m beam. She has aluminium hull and superstructure. She can reach 10 knots with electricty propulsion system. She has a capacity of 10 guests with large lounges and cabins where guests can have a pleasant time. A timeless design has been created by combining traditional design from the past with futuristic design reflecting the future.
Libellula aims to be able to cruise with zero emissions by producing electricity thanks to its hydrogen tanks and hydrogen fuel cells.
OPERATION / FLOW / INTERACTION: The yacht is controlled by the steering wheel located at the stern, all systems of the yacht can be operated from the dashboard located here. You can spend time outdoors thanks to the cockpit located at the stern and bow of the main deck. It can accommodate 10 guests with its 80 square meter lounge, 1 master cabin and 4 guest cabins. The crew team of 6 people is responsible for the navigation of the boat and service to the guests.
PROJECT DURATION AND LOCATION: The project started in July 2023 in Istanbul and finished in September 2023 in Istanbul.

RESEARCH ABSTRACT: J-Class yachts built from the 1930s to the present were examined. The body form was designed to comply with J-Class rules. Different body forms were studied and an optimized body form was used in terms of stability and resistance. Masts and sailing equipment have been placed to maximize sail area. The general arrangement of the yacht has been prepared to provide its guests with a comfortable sailing experience when used outside of the races. Fuel technologies were researched to design an innovative and environmentally friendly yacht and it was decided to use a hydrogen fuel cell propulsion system.
CHALLENGE: Using the hull form of J-Class racing yachts, the design of the yacht was completed by interpreting the traditional J-Class yacht design with a futuristic perspective. In order to maintain the futuristic design of the yacht, innovative fuel technologies have been used to enable it to cruise with zero emissions.
