How would you build the dock and get it into position?

My research shows a general purpose 12"x12" pre-fabricated truss would weigh about 160lbs for 30' length. You'd need two of those, so over 300 lbs (without connectors, legs, etc). How would you get it into position? Rent a crane?

I'm assuming you'd be building this on shore and bringing it over to the island via the crane's barge? I don't think you'd want to be welding this together in/over the water (assuming you brought out 10' sections to connect together).

Sounds like a very interesting project.

BTW - we had the exact same thing happen to us the year after we bought our place. Had Watermark build and install a 20' aluminum crankup.
