Thanks for pointing that out Brk, I apparently misunderstood Shore Thing's comments on dock requests as well. I "assumed" the discussion was about public docks. If I assumed incorrectly, then my entire focus is wrong. (and then I'll be on JRC's side immediately
The vast majority of the docks where I boat here are fairly new floating docks. My entire marina installed all new floating docks a few years ago, and they are left in year-round. Frankly, they're the best docks I've ever been around. At my marina, they set them out early April, which takes a couple of hours. These docks have everything from PWC's and dinghies to a 50' cruiser and large sailboats. No dredging, no pylons, and very limited maintenance. The nice part about the newer ones is that you walk on them solidly, not teetering sideways as with the old style.
