RedactedNarrative: Watercraft #1 was attempting to leave parking dock. Watercraft #2 was tied to the dock with no one on board. Watercraft #1 started to get sucked under the dock (which was higher than the boat), causing damage to the stern. Operator #1 applied power on throttle too quickly in an attempt to overcome the high wind after the stern went under the dock. WC #1 surged forward and went up and onto WC #2's swim platform, causing damage to both watercraft. Life jackets were not being worn in WC #1. Alcohol was not a factor. There were no injuries.
