Pink Foam from Home Depot flotation?

Anyone know how much weight it will float? I managed to get two squares and 2 pool noodles into the tray of my b.o.b. and going to be covering that in two part to make a flat surface and fill in all the gaps. But still questioning if it is enough to float the ski if the scupper lets water into the engine bay.

I will probably end up shoving as many pool noodles as I can into the engine bay as well.

Idk so I might be talking out my butt here but it seems to me that it would depend on the design of the hull and how much foam you can put under the tray to counter for the engine compartment full of water . Also as much foam as you can put anywhere would definitely help . I reformed my RN with the pink stuff from home depot

Well one pool noodle floats me at 160 lbs so 2 should be close to make it "bob" (pun intended). Along with the pink foam I would think it should float. Test it with some weights in the hull before you drop the engine in.

Just thinking out loud...

ohhhhh this makes sense why you layer as much of the pink stuff and THEN fill with 2 part.

Call me crazy, why not just mulch up a ton of pink and just pack it all in there with a solid piece on top and then pour 2 part? does it not work like that? im just preparing for the day i tear into the back of my ski and have to fix something.

I thought about that and it might work. But my none science opinion is that the solid pieces hold more air and take up more space so that makes then more buoyant. I think a huge bag of marble size ping-pong balls filled with hydrogen would be ideal though. :)

cut the pink into slices stack up as much as possible, ( as u already did ) poor a small layer of 2 part on top, easier to sand flat .....

stick to parts of pink under your arm pits when riding u should be fine ;0) .......juuuust kidding

u are getting close to completion now....

Boyancy comes from displacement so it's more about how much surface area the foam occupies.

Buoyancy is a result of density. It's about how much volume can displaced with the least amount of weight.

Nothing solid (that you'd put in your tray) will be lighter than air, but the goal is to displace water with the least amount of weight used, hence why we use foam. If there was no foam and your hull was compromised, then water could fill your tray and your ski sinks like a rock (which happens all too often).

As long as you have some sort of foam (pink HD foam or two part) you're better off than not having it.
