Re: Computer Packing Foam for Foam Replacement?
Just one of many my friend. Pour in foam = no drainage.
Your forgetting that some of use use 3/4"-1" drilled out pvc along our stringers before we pour foam in there for drainage

.
PS. look like your giving the birdy in that pic lol

.
No it is not a joke. Why wouldnt it work for flotation, basically the same principal as foam just on a larger scale, tons of small air pockets.
Tons of water to be entrapped .. good idea short term..but man would I not want to take the shrink wrap off that boat in the spring : ) .
I have 50 pool noodles under the deck in my little runabout....
If she splits in half or something...i'll have plenty of noodles to grab ahold of! lol
On a side note about noodles.. its would be kinda ez for the coasties to locate you when you have noodles floating all over the place ( Im not kidding..good spot for flyovers ) .. Id would float on the beer cooler..but hey.
Kudos for thinking out of the box though!
I Wholeheartedly Agree with this !! Thinking out of the box is what makes this forum Great .. I learn a lot from these guys with something "new" .. just not this one ( cant win them all ; ) ).
Remember that there is more than just water sloshing around inside of your hull.
I hope there is No water sloshing around in any boat LOL !! .. if there is then your foam is the least of your problems. Not saying anything personal against your post there angler..I think we know what you mean

Here is the REAL DEAL on foam and/or floatation methods from a professional point of view..
Some boats require foam for "floatation".
Some boats require foam for "integrity" .
Some boats have foam in places where it would not require it ( waste of time and effort ).
Some boats have foam in places just to fill "dead" areas that could be used in smuggling contraband ( trust me I have seen it )
For non structural boats I see no reason not to use the "pool noodles" if properly sealed/welded at the ends for flotation in NON-Structural foam builds ! ( just pay me 90 bucks an hour and It could cost you more then the boat is worth for a noodle install )
Plastic bottles are IMHO the best because of there shape ( mostly rounded ) and cant really trap water between them therefore draining to the bilge and evacuated VIA pump or plug ( never seen a plastic bottle mildew either ).
Any other kinda of material that will not allow water to completely drain into the bilge will eventually mold and mildew. Leaving those spores to come into the cabin area ( if you have one ) or cushions etc. You cant just start cramming PC foam or wrappings into your boat without long term side affects.
Structural foam build boats needs that 2 part foam reinstalled just like factory. You can add some modded drilled out pvc to the lowest point of the compartment to aid in the drainage of water if you like.
Foam is one of two things .. Structural ( needs to be re-foamed ) or Floatation.
Noodles or bottles might work for you..but not the next guy. So make SURE you know What YOUR boat needs before Foaming or using an alternate floatation system.
YD.
