Build a new swim step

I have to replace my teak swim step, it is broken at various areas.
I am wondering if using marine plywood would be a correct choice to build a new swim step (it is easier to find than teak) or if teak is the only way to go if a wood swim step is what is needed.
Any advice? Does the plywood get worse than teak with age?

Don't use ply. It won't hold up, and isn't as strong.

Do it right and build it with teak, buy a used platform at a marine salvage place, or get/build a fiberglass platform.

Ipe is another hardwood that will work if you cant find teak.

How would plywood work if it was sprayed with some type of bedliner?

I was thinking the same thing of using plywood sprayed with bedliner. I have a sheet of 1-1/8" ply that I got for free and I could use my existing brackets so all it would cost me is the bedliner material. If my project list ever gets any shorter I might just try it.

I am just finishing up that project now. All I have left is to get some gator grip and put it on. Its all painted. I used 3/4" marine plywood. I made it two sheets thick.

I made a "false" swim deck for my last boat. I like not having to teak my platform. Don't have to worry about this one. If it get scratched or hit is no big deal.

A sheet of 3/4" marine plywood is $75 here so I used treated. It was almost $40. I used 3 quarts of paint $30. And I used 5 cans of clear coat. So this project has cost a $100. It is going to be over $150 with the gator grip. I didn't do the rhino lining just because I thought the paint would look a little better and be a little cheaper. It took a very lone time to do this project. It is a lot of work but also with all the coats of paint and drying time it takes a long time


I would recommend putting that money towards a teak deck if you don't have one. But if you just want a spare deck or one that is going to get trashed then this is the way to go. It is also kind of cool to make it a little longer.
