Dropped floor
Also: lowered floor
A dropped floor is a lowered floor: it hangs below the bottom edge of the tubes.
Alpacka uses this construction on whitewater boats like the Mage or Valkyrie. The paddler sits lower, the boat sits more solidly in the water and is easier to edge. Flat floors are simpler and lighter.
