I'm looking to add a floating dock section at the end of my existing 4' aluminum dock. I'm not quite sure how to attach these big hinges to the aluminum section. The frame is quite beefy but I still feel a bit iffy about drilling 4 holes per mount for some bolts.

Am I being a bit too paranoid? Here is a picture of the aluminum dock, ignore the crack :)

first, get the dock welded up

then drill holes and attach hinges with thru-bolts
