how much flotation does a 4x8x.5 sheet of the blue foam boards have? has any one tested this or seen a number?
JMichael said:I'm using the blue foam in my boat. I just calculate the number of gallons of water it will displace to see what the approximate flotation gain would be. In the case of one sheet that size it should be around 63 lbs of flotation. If you're trying to figure how much you'd need to keep your boat from going to the bottom there is more math involved though, because everything is lighter under water than on the surface and you'd have to calculate that into it.
