The purpose of this study was to determine the tensile, fiexural, and impact strength of coir composites as fishing boat wall materials. The stages of this study were: (1) preparation, procurement of materials, coir treatment, composite manufacture, testing, and discussion. Before being used as a composite reinforcement, coir was soaked in an alkali solution with a concentration of 20% for 3 hours, then dried in an oven at a temperature of 90°C for 5 hours. Coir composites were made with three types, namely 20%, 25%, and 30% coir, respectively. After that, tensile, fiexural, and impact test specimens were made. Based on the test, the highest tensile and fiexural strengths were obtained in coir composites with a composition of 30% coir, respectively 21.04 MPa and 44.71 MPa, while the highest impact strength was obtained in a composition of 25% coir, namely 4.3 kJ/m2. It was concluded that the higher the composition of coir, the greater its strength.
