Like Clayton said, fish get used to these surroundings. The only thing that may effect your fishing is the wake from these boats and what not may make the water a little murky. I make my own buzzbaits and ive caught numerous fish. Just don't lose your focus and keep your confidence they will continue to bite.
On a side note if you can throw the buzz bait up on shore and come into the water that way it makes the fish believe more in the action of the bait. IE its a snake / frog / mouse or what not. Just my 2 cents
