has anyone checked out the pure glass bonzer?
found at http://www.houseofbonzer.com/
you mean this?
crazy. how’s this get done? removable bladder? burn out the foam?
Looks like they used a plywood core, look at the wood pattern that was left on the bottom of the board
That is the effect of the material on the light passing through it.
Exactly. Called “moire” effect. Like when you look through certain window screens at an oblique angle. Its just the weave of the cloth refracting the light, slightly.
I like that for a look, but if it’s a rider at all, it’s going to be heavy!
No way a standard glass job will hold up and not fold with the foam not there. On the other hand, it looks possibly like one of those short-lived hollow perspex numbers by Ukelele.
I can’t imagine that’s a rider, but it sure looks cool. I think they had to have glassed it heavy (to hold the shape true) then meticulously cleaned out the foam inside the board after splitting it along the rail. At least, that’s the only solution I can dream up other than a molded board, but that would have to be two halves glassed together.
Is it impossible that they built it like a fiberglass fin? I mean, a lot of fiberglass layers and a ton of resin, then shape it the same way you would foil a fin somehow?
That may be a very stupid question I know I know…and the board would maybe weigh 25lbs and float like a rock hahaha 
Some guys before most of us were born (WWII era) were doing this sort of thing…

a lot of hollow wood surfboards weigh in the neighborhood of 25 lbs. - couldn’t imagine a solid fiberglass / resin board weighing that little
I reckon they took a normal glassed foam board. Taped off at the rail apex, covered it in a release agent then glassed over it. Popped it off and repeated on the other side. Married the two halves together and glassed over the join.
Sure is cool looking…
Seems to me the pattern you see is the double concave bottom contour shaped into the fiberglass panel. Like a volan fin…
Fiberglass with résine weight around 2kg for 1liter, so a plain 30 liter shortboard weight more or less 60 kg. I would not carried it over my head lol.
60 kg = 132 lbs !
Are there pics of it being surfed?
It’s very easy to build it light, but making it strong enough for surfing is something else.
It doesn’t look that heavy:
It’s filled with helium gas pumped up like a tire to 35lbs pressure. The pressure gives it rigidity and the helium makes it very “floaty”. Matter of fact it’s so light you can carry it around like a ballon.
