In the Galapagos Islands, there is an important fleet of coastal vessels for navigation between islands, with a length of less than 15 meters and constructed of fiberglass reinforced plastic (GFRP). The proposal to modify the hulls of the new ships entering the islands is presented, with viscoelastic sheets, to protect from the damage caused by the slamming phenomenon and increase its useful life. Through the reproduction of cyclic load fatigue tests, in which the evolution of the damage at the level of the laminate is observed, and by the characterization of the results to compare the levels of microcracks induced by the impacts. It is verified that the modification introduced in the laminate significantly reduces the repair times, protecting the environment.
