RedactedNarrative: V1 was n/b in the icw just north of the las olas bridge creating a large wake. V2 was moored starboard side-to at the city of ft lauderdale las olas marina, at the northern most dock with numerous fenders. The wake from v1 caused the starboard side of v2 to hit a wooden dock piling and also damaged the boarding ladder. V1 did not stop and continued n/b on the icw. I was unable to contact the captain of v1 on 09-09-15. He advised that he was not going fast enough to cause a large wake. Nfi.
