What foam can be use for bouyancy??????

Hi: Ike, I found locally a foam tubes without the hole in the middle completly solid, I try it with me and they float more than the other one, cost me work to sumerge them. Know this is the problem I'am not to good with formulas and I try to get my results without luck to funny numbers. In overall weight my boat with all the teak he have added, the tall mast, generator etc have like a 1500 pounds more. The boat displacement originally was 6000 pounds, I want to round up to 8000 pounds. How I know how many foam tubes I need to maintain the deck flush with the water without assume the gasoline that will help, woods, etc, just 8000 pounds??? Please if some or you Ike can help with that i will appreciate, I have a lot of places goods for the foam tubes all of them in sides or under the deck. My father found a company that they can sell me the pin pall balls for .25 each but I still don't know what are the flotation but sounds better two me because they are stron plastic resistant, more cheap and more managable. Thanks again. Mario

 

$0.25 each for ping pong balls is NOT cheap. My off-the-wall guess is that it will take 50-80 of them to equal the buoyancy of a single foam tube.


Seriously Mario, just get someone to help you with the math and figure it all out. It should only cost you the price of a six pack.

 

if your trying to go cheap,put in some plastic bottles,maybe fill the hull then seal it off (not a great idea,though)or,if its a flat bottomed boat,just glue on some Plastic bottles,milk bottles,polystirene,wood etc,though this would make it a raft (wich are great,i even decided i would build a raft for open seas!),wich dont sink so it is on the idea of making it unsinkable.
