RedactedNarrative: V1 at anchor and fishing was struck by V2 at the North Western fender of North bridge in Fort Pierce. V1 was at anchor just outside the Northwest fender of North bridge in Fort Pierce on the Indian River, and was outside the marked channel. According to the operator of V1, V2 was southbound on the Intra Coastal Waterway and while waiting for the drawbridge to open, encroached on the bridge very close. As V2 sat idle awaiting the bridge opening, the wind blew V2 into V1, striking the starboard corner of V1's bow with the starboard hull of V2 slightly aft of the bow. The occupants of V1 waved and tried to gain the attention of the operator of V2 prior to impact. The operator of V2 attempted to maneuver his vessel away from V1 and in the process of doing so, ran over the anchor line of V1 which first entangled the anchor line of V1 in the propeller of V2 and then cut the anchor line of V1 after the impact.
