Abstract
This paper presents the design of an eco-friendly catamaran that follows two design methodologies, one focusing in the importance in the needs of future users and the other the spiral boat design methodology.
 The prototype is going to take advantage of the unique form of a catamaran and use the space available between the points of flotation for the process of extracting small plants and light plastics from the surface of recreational lakes. With the prototype the esthetics and also the aquatic ecosystem of the lake would be better preserved. The application of the prototype, could improve the time required to recollect the duckweed and only required one operator; however, the potential of this project is significantly bigger as it could be used as a method to extract superficial contaminants in garbage patches in the ocean and lakes without harming the species still in the zone of operation. Good practices of engineering are going to be use for the design of the catamaran, as well as for the selection of the necessary components.
Highlights
Nonmoving water always cause certain problems in recreational lakes or in considerable size open field deposit of water, where an aquatic plant named duckweed manages to grow due to bacteria presence [14]
The plant is necessary in the lake in order to maintain the food chain in the aquatic ecosystem, his overpopulation bring the previously mentioned problems
In recreational lakes, the duckweed doesn’t give a good aspect when the lake is opened to the visitors, the way of removed it is manually by at least 2 employees, taking at least six labor hours (Number given by the City Hall of Santiago de Surco)
Summary
Nonmoving water always cause certain problems in recreational lakes or in considerable size open field deposit of water, where an aquatic plant named duckweed manages to grow due to bacteria presence [14]. The main problem with this plant is that it doesn’t allow the sunlight to enter to the aquatic environment, degrading the ecosystem and because his fast decomposition it generates not pleasant smells [14]. The objective of the project is to learn, design and simulate an eco-friendly vessel capable of recollect superficial plants; this means that the ways of generate power and the material of the hull constructions had to be ecological
