Benoit Jr. Zachary C. Blanchard Alex M. Rutfield George H. Williamson IV Marine Safety in Puerto Rico 12/17/2013 Abstract Despite warnings against dangers in the water, swimmers are continuing to drown at Puerto Rican beaches. The goal of our project was to improve maritime safety through warning signage and the education of beachgoers. Using resources at the Department of Natural and Environmental Resources, we evaluated high-risk areas and used interviews to determine how well swimmers comprehend the dangers. Based on the analysis on the information we gathered, we made recommendations to better educate the public. The recommendations, along with a database, will ideally improve maritime safety in Puerto Rico. i Marine Safety in Puerto Rico 12/17/13 Acknowledgements We would like to thank the following people
