I was just curious ,does any one know the actual Advantage of 4lb vs 2lb foam.I realize the density difference,but what are the specifics advantages other than costs?

Quite simply put, it is a simple rule of physics. The more mass density of a product, the greater the intended displacement. Warthog, you and Wilson are on the money with your advice.

A cuft of water weigh's 62lb. A cuft of 2lb density will support 60lb's of floation.
A cuft of 4lb density will support 58lbs of flotation. The 4lb density will resist at least twice the water intrusion that the 2lb density will and if used for renforcing the boat will be twice as strong.

Just a tiny addition, the density of saltwater is 64lbs/cu ft. And in case you are interested in figuring out how much foam it will take to float your boat, the density of fiberglass is something like 125lbs/cu ft.

I've found some foam thats even more dense,6lb,8lb'10lb.At what point is it overkill or a disadvantage if at all ? And would it be even better with any thing higher than 4lb? I'm refoaming the whole bow and the tank of a 17.
ReefKeeper,Whats up VB?Glad to hear from Ya! I'll take that foam off your hands. I'm at the beach as well.My tank should arrive any day now and Im so behind on everything.did you mean the can says 8 cubic feet? I'll call ya tommorrow.
Wilson, looking at your mako, I don't believe you have a science poor brain[;^)]
