RedactedNarrative: On 5/9/2021 I responded to a call in reference to a vessel striking a dock.  After arriving on scene, I determined there were no injuries.  I observed the pontoon boat to be partially through an exterior wall of a boat house.  Upon further investigation I observed the pontoon boat to be resting on a 6x6 post.  The exterior wall was resting on the bow of the vessel.  The vessel was pinned between the exterior wall and the 6x6 post.  Upon further investigation I observed the lift inside the boat house to be pushed over into a center beam.  The center beam was broken and resting against a vessel on the other side of the boat house.  The 6x6 post the vessel was sitting on was eventually removed and the vessel was freed from the structure.
  I after interviewing the operator, he informed me he was traveling along the edge of vegitation (approximately 30ft from the shore he informed me he looked behind the vessel briefly before coming to a sudden stop. While speaking to operator 1 I did not observe any signs of impairment. OP1 informed me there were no mechanical issues with the vessel prior to the accident.
