OK guys another weird idea of mine
   
  I have the idea of using a fire hose for a VBT. 
  I am a volunteer fireman and one day putting out a fire it dawned on me 
  that say a 3" diameter 
  hose could be used for a soft VBT. It could be run along the perimeter 
  under the super structure
  of my sub. The two ends can be screwed together and an air line attached. 
  We have tested these
  hoses to 600 psi and are very very durable.
   
  Any thoughts on this? 
   
  I would be using this when extra equipment and or weight would be 
  onboard.
  Not to mention an additional safety item.
