RedactedNarrative: LA 6529EN, 1994 17' Astro was cruising south in the Vermilion River in rainy conditions. Upon approaching the bridge crossing LA Hwy 353 (Prairie Hwy ) the operator stated that he slowed down to approximately 5 mph to navigate through the bridge that was congested with floating debris. As he attempted to negotiate a slight turn to starboard in an approximate 2-3 knot current he temporarily lost steering (dual cable system jammed up) and subsequently struck the concrete bridge support pilings with the port side of his vessel. The collision caused moderate damage to the fiberglass on the port side of the vessel approximately amidship of the vessel. Aside from the operator, the vessel was occupied by his 4 year old daughter and his 32 year old brother (see attached witness statement) The operator stated that the steering jammed as if floating debris caused his steering to malfunction temporarily. 
  There were no injuries reported and the operator stated that all occupants were wearing properly fitted PFD's.
