TIRE TUBES FOR FLOTATION???

[K9Kampers]

remember, im not saying that im safe with this foam, im just saying that its better than the emptiness i have now

I just use alcohol to placate my emptiness!

The definition of the "water logging" of the foam depends on the timeframe. In the practical short-term the foam will keep you afloat until you can be rescued, the wet foam might keep you afloat for months, even though its capability is continually declining with time as it absorbs water. The timeframe I am familiar with is about 4 to 6 months, in that time I have not run into any of the above mentioned foams (including the type that comes with the boat from the factory) that did not take on water (as judged by their weight increase). Some blocks with 2+" sections then took several weeks in the outdoor sun and wind to completely dry out.

Your test is valid TaZ, use that foam (as far as floatation is concerned), and yes, you will need less in salt than fresh water.

I think that drinks hidden there might be called expanded polyethanol???

Wrong kind of alcohol.

Oh Yeah watch how fast it dissolves when gasoline is spilled on it accidentally or not

I think airbags that would inflate enough to keep the boat from sinking could be actually made into the boat from the start. Just like airbags in a car. They could be hidden behind the liners.
How and when they got deployed would be a good discussion.

I'm US ARMY RETIRED 67N (UH-1 helicopter repairer) and came back to work (civil) with the Robinson R22 & R44 (piston engine) helicopter

they have a system not far from what you are saying, is call "pop-out floats" is like an airbag on the stand rails, come with a 5000psi helium cylinder
and is reusable if you deploy it.





something like that for a boat can be design to hold a sailboat.....if you drop the portapoti and the OB

That's an interesting system. I often wondered why some helos that fly over water didn't appear to have floats, like the old Bell 47's with the giant pontoons. I guess there's one answer right there - they're not always obvious.

As an aside, I actually took a few lessons in an R22 (I have a fixed wing ticket), a couple of decades back. I remember when they first appeared on the scene. Pretty nifty for a start-up helicopter manufacturer to actually make it. And piston engine yet. But that super low mass rotor system always made me nervous regarding an engine-out situation. And they're too expensive to fly just for fun.

Not that fixed wing is cheap.

Or for that matter, boating.

How does the pilot get out and pump up those floaties in the air with no ground to put his tire pump on? He can't land on the water and THEN pump up the floaties or he will get his feet wet. Somehow he needs to pump up the floaties before he lands on the water, right? (Or are they like beach balls and you just blow into a hose?)

the pilot just pull a cord in the cocpit or a push button (not recomended) that activate a a 5000psi helium cylinder that inflate the two pontoons

Don't they have stuff like that on the Apollo Space Capsule so it does not tip over during spashdown? Maybe they make one for the MAC?
