It does not work well where vegetation protrudes through the water surface. In this case, the net is lifted and the berries are left behind. It is also necessary to use short lengths of wooden booms to feed the elevator from the larger mass of corralled berries just as must be done when using long strings of wooden booms for corralling the berries. The inflatable boom works very well with the boom-tug described in CRANBERRIES Vol. 45, No. 8, Aug. 1978. FABRICATION OF INFLATABLE BOOM Fabrication of the inflatable boom is relatively simple but may require more time than first expected. The first step, obviously, is to acquire the necessary materials for a boom of the desired length. These consist of the following: Flexible tubing-50 mil. thick, PVC or Vinyl, collapsible tubing. Nylon fish netting-No. 18 nylon thread, Vh inch stretch; measure (% inch square), 24 meshes wide. Cable-1/8-inch galvanized or stainless steel cable. This should be at least twice the length of the boom. End plugs-two metal end plugs for the tubing, equipped with small, quick shutoff valves to provide for inflation and deflation of the tubing. Couplings-lightweight metal coupUngs for joining lengths of tubing together. Tubing clamps-Stainless steel strap clamps for clamping tubing to end plugs and coupUng. Wiring harness clamps-nylon electric wiring harness clamps for attaching cable to netting at 15 foot intervals to prevent sliding of the cable through the netting during use. After acquiring the tubing, netting. Figure 2. Inflated boom corrallin
