Actually - the Coast Guard has manufacture / boat building regulations that require usage of flotation foam that must be used depending on design criteria, floatability etc....
That particular regulation guide is a "easier to understand" version than what actual manufactures have to adhere to.
So - its really not a "marketing spin" per se - but if one has to do it, may as well use whatever marketing points you can get out of it. That document may help to OP calculate how much foam is actually required.
