Well my old teak platform is cracked and I got nothing to do so I started making a swim platform. 3/4" non treated ply wood and a couple 2x4's cut lengthwise and this is how far I have got. Today I put on the first layer of fiberglass resin. Another layer of that tomorrow then to finish it up I will put two layers of the Rhino liner on. I'll put up pics when I'm done.
