pool noodle question

The dollar tree store has pool noodles for 1.07 a piece so I bought 20 and put them in my Cobra Triple. Will that be enough to keep it floating? Does that price sound like the best or can I get them cheaper for my other yaks?

I doubt you can get 'em cheaper than the dollar store.  I think 20's plenty.  I put a dozen in my X-Factor.

 

IMO: skip the pool noodles and get floatation bags (for bow and stearn) specifically made for kayaks.

As written by a buddy who now lives in Iowa...

maybe somebody already said this but...density of salt water is about 64 lbm/ft3, so if you want to float say 300 lbm stuff (big dude + 50 lb kayak) you would need to displace 300/64 = ~5 ft3 of water.  if you can get 5 ft3 of foam crap in your boat and the rest is water, it should float with you on it.
that's a lot of foam though.   

The reason I went with noodles and not bags is a guy named Dan - shark bit through his boat.  If the bite were a bit more severe it would have sunk him without flotation, and a bag could've been punctured by the bite.  Sounds like time for a new video investigating whether my dozen noodles will float me when totally swamped.

 

This subject has been duscussed before - here is the link.

I want to put my triple in the pool and see if it will float with the noodles. I don't think I could ever get it out though once it was full of water.

not much can beat the inflatable bulkhead but the pool noodle offers a functional storage system that uses up dead space and keeps your gear where you want it. It will not save you from having to bust out the pump after a swamping but the floatation it offers can help make the situation go smoother. I recently put a bulkhead in my 140 that holds rods and can keep tackle boxes in place. Then shoved as many pool noodles as I could into the unused aft section.
