I received the board !
Dimensions: 104x54cm (41'x21')
It is definitly not a bodyboard, it is a plastic version of a plywood paipo.
It is made of a 1cm thick pvc plank, it is a material I easily recognize as I used it when I worked in the printing industry.
It is solid, has flex (more than plywood), as heavy as plywood is, it is a material that is easy to cut or sand.
It is also easy to bend this material using heat.
So it is just a plank, no channels, dead flat (except the nose rocker), they glued a piece of foam on the deck for confort I guess.
It looks good, I'm sure it will work well.
My wife is not a big fan of the prints on the deck, but I like it, reminds me the glory early 90's !
