The operator had been viewing fireworks at Westport and were coming in to Wilson Cove. The vessel went around the outside of Sheffield Island and came in from the west. Radar and GPS were working, but the operator failed to see a floating sturcture low in the water as the vessel was slowing down at the entrance and hit the platform on the side and top. The operator thinks he went over the platform at some extent. The operator circled around to see what had happened and continued in and checked for damage. The operator contacted the platform owner the next morning.
