Abstract

Tourism is one of essential sector for economic development in Indonesia. With Indonesia’s enormous sea area, the growth of tourism in the maritime sector has become a major concern. Given the possession of the seas, there will be various marine tourism destinations with good natural conditions that draw tourists’ attention, one of which is The Bunaken National Park, which is located in Manado. The data shows that the number of tourists increased throughout the year, rising by 23% for domestic tourists and 12% for international tourists between 2002 and 2018. Therefore, in order to support the tourism industry, a vessel that can accommodate tourists is required so that they can experience the underwater beautiful scenery. Thus, we innovate to develop a semi-submersible tourism ship, which is a ship equipped with glass at the hull's bottom so that tourists can easily enjoy the underwater ecosystem's beauty. This ship is a trimaran with a length of 23.1 meters and a passenger capacity of 44. She has a maximum speed of 12 knots and a draft of 2.22 meters that can be submerged up to 2.5 meters to maximize underwater visibility. The objective is for this ship to attract more tourists, which will help improving the local economy.
