yeah... that would be the way to go.
ok replace the ping pongs w/ chem resistant :biggrin:

what about the HEAT generated by the foam? I'd test them as well to see at what point they start to melt....

come one man.............. 2 lbs.........
that really is a good question, I have 4 lbs that I am using.
Uh, not sure thats sarcastic or not. I mean for 2 lb density foam. I understand that 2 lbs of foam weighs... 2 lbs.

I honestly dont know the really difference, my guess, is based on a measurement of weight in say 1 cubic foot, the weight may be 2 lbs or 4 lbs respectively..........

4# per cubic foot and 2# per cubic foot respectively.......
:biggthumpup:
I read it on the side of the can or foam I bought.

whats next go-cart tanks inside surf skis??? just gotta bust some balls for thinking outside the box, it happens to flatwater guys with new ideas all the time. you would think a surf ski would want all the strength one could get out of it and have enough foam in it to keep it afloat if a big crack were to happen. oh well, it ain't my ski.....go for it.

latest idea:
how about packing the voids w/ polystyrene foam (the stuff that doesn't absorb water) like out of a cooler or the bean bag. if it's an old cooler, just shread it down to small individual cells then pour foam over that.... It seems to me you still have the rigidity, but the bulk of the material would be unable to retain water.
Or maybe mix it into the foam before you pour it... not sure which would work better????

That sounds like that would work a lot better then ping pong balls, crushes still easier then regular foam, but is a LOT lighter per the same given area. I have a couple sheets in the basement, I may even try that myself.
Why not just put the sheets in? Probably would compress a lot better that way. Individual cells sounds like it would be hard to get an even mix while the foam is expanding.

I'm open for disscussion bro... lets work it out
larger pieces are good for the gunwhale area... I was just thinking smalller chunks = more polystyrene per cubic inch of foam...

hey Nick, I would stand the ski up on the nose, put your ping pong balls or crushed up foam in about 6", then pour foam so it runs into the voids, the pack and pour.... repeat until full....... instead of trying one big pour.

well if you want to use polystyl, then why even use expanding foam?
what if you just cut the tray wide open, and layed big sheets of PS in there...then just shaped them to fit around the waterlines and such...
