Mainly the handrails. The guy that built it has some openings that swing up and leave an opening in the railing. They don't latch very well. Only thing I can figure is that it was for getting in/out of a boat but at full pool, the water is a foot or so below the deck. That and a few boards here and there. It just needs a little TLC

It's true hard work never killed anybody, but I figure, why take the chance?
