Re: Physics and buoyancy question

Sorry guys, I became rather side tracked on a number of other items.

After a number of floatation tests with pool noodles and the blue insulation foam I found that the pool noodle will allow water to permeate into its’ cell structure after time (hours that is), where as the blue foam does not.

Using just simple floatation test using lead to represent the weight of the boat I was able to determine how much foam would be required to float 8 lbs. Then after some creative forming and cutting of the foam, was able to fit just enough foam in the un-used spaces of hull so in the event of flooding the model will stay afloat.

So many thanks to everyone for the input as it was greatly appreciated.
