Easily attach a dock ladder to your dock or seawall to provide an easy method for returning to dry land. Make sure to choose one with enough steps (and overall height) to make climbing out of the water as easy and as safe as possible. Also consider the kind of material you want for your dock ladders, stainless steel or aluminum. Both materials are easy to clean and resist corrosion. Though stainless steel is a little heavier than aluminum, it does make for a superior, more durable swim ladder for docks.
Another important factor is choosing a dock ladder that allows for dry storage. One of the best ways to combat corrosion and algae growth is dry storage. For this, folding dock ladders and ones that flip or lift out of the water are the way to go.
