The focus of this thesis is to create a new conceptual design for the redesign of the superstructure of the speedboat "Freedom." The speedboat Freedom is the most popular product of Samudra. This product is now 12 years old. It has not received any upgrades. It is losing its market share. Due to the old manufacturing method, it takes 11 days to make one of these. It could be reduced to 5 days if the seats could be integrated into the deck mould. This type of boat is usually primarily focused on aesthetic and practical aspects. However, there are customers requesting performance, which will be the main focus here. A supplementary task is to find ways to apply an engineering approach to the design of a recreational craft in order to help small craft manufacturers optimise their products’ performance. The resulting design is intended to fill the void of large, high-performance superyacht tenders with its lightweight hull and powerful engines. In Samudra, hulls are designed according to naval architect standards. Deck is designed and made in house according to user needs. For large boats, FRP ribs areused as stiffner.They have hull moulds in various sizes and uses them as per customerrequirements. For example they make water taxi with their 7 meter hull, and a force traveler body as a deck mould. So it is possible to use traveler windshield and glasses for the taxi, which is economical.
