Bowrider Fishing Platforms

Anyone have actual pictures/instructions for adding bow/stern fishing platforms (with seat) ?

I've found many links and such but everything I've found refers/links to images and/or content that's no longer present.

I need something that's removable and will spend most of it's time OUT of the boat. With the parts usually not being in the boat do they still need to be marine grade plywood or can I just seal/paint really well then cover with an outdoor carpet?

tnx in advance.
