RedactedNarrative: Vessel #1 was coming through the Channel under the Bridge and was hit by vessel #2 on the east side of the Bridge.  Waterway has a very narrow view and Vessel #2 was underway and did not see Vessel #1 until collision.  Witness said a vessel ahead of #1 said opening was clear so Vessel #2 was underway to go under the Bridge.  Bridge is one-way traffic  and it is difficult to see approaching vessels from east.

Both Vessel owners reported they have insurance.  Husband of Vessel #2 operator, was also on board and had been operating vessel earlier.
