Easy peasy.

So my bait tank battery does on me during my islander trip and I was love bait less for the whole afternoon so I want to build a bait tube as back up to take along.
Is there a reason that we want to build or use floating pipe instead of sinking pipe? I heard both ABS & PVC float
Thank you for your help!
