I am pretty set on the floating dock RC. Zep, a floating dock adjusts without the touch of a button and that is what I am after. A stationary dock would at times be completely under water when the emergency overflow is in use. That could last for a day or so and I would hate for it to become unanchored and float off or sink. My biggest concern is establishing the shore anchor system to be the only anchor point, no legs at all.
I envision a concrete pad/pier on the shore a foot or two above full pool with a large hinge device attached to the gangway. The gangway might have a float or two under it near the platform (or not). Then a hinge between the gangway and platform. As the water level changes the hinges allow the platform to stay level but change with the pool. It works in my head, but sometimes my head lets me down and that would be a waste of money, blood, sweat and then tears. Hence, throwing it around here on PB!
dlowrance - what kind of binds does your dock get into, do you have any pictures of it, bound or not?
Custom, the local used barrel guy asks over half much as these (at sale price) would cost to do the same job and I am betting that the low profile design helps stability much more so than what you get from barrels.
