I've only used my swim ladder once, and I almost
couldn't get back aboard. The main part of the problem is my immensity and clumsiness, but the ladder is also very short, and there's nothing much to grab onto.
I ordered this one to replace it.
It's a lot longer, and it's got the handrails. I haven't installed it yet, so I'm not sure if I can recommend it, but it seems reasonably well built.
