Operator/owner was locking thru the Ballard Locks in his 55' cabin motorboat.  While his vessel was tied off in the big locks, a sailboat that had 2 other boats rafted to it released the bow line causing all three boats to swing in the current into owner's boat.  Because the sailboat was still tied at the stern to the lock wall, it pivoted back into owner's boat.

Damages were estimated to be scratches and gel coat scraping totalling $2,000 or more.
