Mooring ball question

[Bear Guy]

I have never left a float in the water through a winter season. On the winters when our mooring chain stays in the water (it gets pulled out and replaced about every 3 years), we tie a length of nylon rope to the float end of the chain. This is then stretched toward shallower water. The loose end is tied to a brick and the brick is placed underwater next to shore. This can be picked up easily in the spring.
