Anyone know where I can get super dense, walk in freezer box foam or something similar? I want to find a foam which has enough structural integrity that it doesn't have to be glassed. If anyone has seen Ryan Burch surfing a block of foam in Stoked Broke you know what I'm talking about.

I have a very large 4"-5" thick piece of foam simular to a Boogieboard. Its around 3X5.5 foot. I bought it a while back to make a waverunner rescue sled for tow-in surfing but never got around to doing anything with it yet. Paid like $100 for it so if you need it I can sell it to you for a few bucks less.

I'm interested. It might be a little bit shorter than I intended, but I think I can make up for it in thickness when shaping. Is there a place that sells the foam you have?
