Surfing Waves

What type of surfboard is this name related to.
Gut slider.

I think it is a board, longer and wider than a Buggiboard. You surf it prone, lying down and paddle with your arms. No flippers.

But not sure.

Thanks.

that is it in a nutshell, hard or soft, also known as a belly board, Paipo, gut sliders are not new been around just obscure history notes as standing took over!
