RedactedNarrative: On April 25, 2022 V1 a 59' Marlow cabin motor boat was heading East bound in the St. Lucie River just East of Indian St. Bridge at approximately 20knts. V1 was operating in the channel and there was no slow speed zone for the area.  V1 passed Yacht sales' Marina pushing a large wake as the vessel passed it came down off plane and slowed. The large wake caused the vessels in the marina to rock and bang into the docks where they were tied up. V2 experienced damage in 3 sperate locations on the wooden and stainless bow rails. The wood was broken and the stainless was scratched and surrounding gel coat was scratched.  V3 received damage to the stainless railing that held a paddleboard and damage to the paddleboard. the railing was bent and lifted up where it was screwed to the boat and the paddleboard had scratches. V1 was operating in the channel not violating any slow speed zones but its large wake was the main contributing factor to the damage of the other vessels.
