Floatation that works please

[Panther6834]

I've been a certify Scuba diver for almost 40 years and it comes in handy. Plus a guy can never have too many hobbies.

Something like an air bag stuffed in the hull away from hot and moving parts might be an idea ?

If such could be permanently sealed (ie. no permeation/off-gassing of the air), and stuffed into the bow, that actually sounds like an excellent idea...essentially, a bow-shaped BCD. Even better, instead of being filled with air, having it filled with helium (lighter than air) would be even better. Seriously, I wonder why no one has thought of this before.

The only possible problem I see with this is finding a non-permeable material, or being able to utilize a small air-fill nozzle That wouldn't encroach the space needed by other things that would normally be placed close by (ie. batteries, motor, ESC, etc).

I used to run with a guy that would put together a stirng of ping pong balls. He used shrink wrap like we use for batteries to tie them all together. Looked.......well........wrong.....but it did work. You're limited again by the shape but that air was staying in the ping pong balls for sure.

Just remembered this too. You can also use pipe insulation. Because it's smaller and a bit more flexible than noodles you can sometimes actually get more foam into a cavity. 5 pounds of crap in a 5 pound bag so to speak. With noodles you have to cut and trim and shave to get them to fit just right and even then you likely have a gap that could have had flotation. Another idea.

Well folks today and persistence paid big dividends, I got my boat back, pictures show my buddy Joe who scooped it up with a 16 ft pool pole net.
Pool noodle floatation, the boat full of water with all hardware must have weighed at least 8lbs plus it was heavy.
saved the motor that?s about it.
The stock large cat pack on the ESC one of the Caps broke off from corrosion, the servo, and receiver are shot also but I got her back I?m so thankful,
I spent 10hrs trying to get her back, persistence, no more poodles for me they didn?t even come close to floating this boat

I ALWAYS use spray foam....try it !! Fills every void in the nose and sides or wherever so that water has nowhere to accumulate in those areas. Plus helps big time with major crashes that can damage the hull...foam helps keeps her together !!

Old post but still relevant. I conducted an experiment to determine if pool noodles will work on my new build.
I'm 6"3" and 240lbs.
I went in my pool with a single, uncut pool doodle. I put it in the water and sat in the middle of it. It kept my head and part of my shoulders out of the water.
I did this for 30 minutes while sipping margaritas. I was figuring that I should be able to retrieve my boat in 30 minutes.
Once I was out of the pool I squeezed the pool noodle to see if I could get any water out of it. I did, but very little.
Confused as to why Froggy is sinking with pool doodles?

Gary, could you please explain exactly what spray foam you used. I was looking and there are many kinds. Also, where did you get it.
Thank you,
