Step 3

THE BAR CRUSHER PHILOSOPHY...
 BACK TO STEPS

'The challenge is to build a boat so well braced that deflection under stress is virtually eliminated. Bar Crusher boats, like aircraft, are built to withstand extreme forces.'
 
More on sub floor framing systems...
There are two typical sub-floor systems used to build plate aluminium boats.
 
1) The way just about every other manufacturer builds plate boats
 

2) The way Bar Crusher builds a plate boat using RigideckTM

 

1   THE WAY JUST ABOUT ANY OTHER MANUFACTURER BUILD PLATE BOATS (CROSS FRAMES & FLAT BAR)

 

Many plate boats use cross-frames and flat bar to strengthen the hull structure. This technique involves the placement of a number of frames running across the hull set at varying distances.
 
Between the cross-frames, flat bar (typically 50mm x 6mm) is often stitch-welded to the bottom plate.
This system is commonly used in the construction of most other plate boats in Australia. If the cross-frames are situated too far apart, the bottom plate of the boat can deflect and deform. The flat bar provides some strength, but it needs to be braced properly to minimise deflection.
 
 

 
 
THE WAY BAR CRUSHER BUILDS A PLATE BOAT USING RIGIDECK®
 
Bar Crusher's RigideckTM system is the toughest hull building system in the world. RigideckTM uses full-depth and full-length longitudinal frames so everything is boxed and triangulated. For even greater strength we use cross frames between the longitudinal frames to tie the whole sub-floor together.
 
If you think of an aeroplane wing or aerospace honeycomb structure you can visualise the RigideckTM system. All the sub-floor framing is braced in all directions to cope with tremendous stresses. The diagram below demonstrates the RigideckTM sub floor system. (The reason every boat builder doesn't use this system is because it's more expensive, harder to do and requires better welding skills.)
