A floating boom can be designed to fence off trash. It is fabricated from a series of buoys on which a skirting is attached, customized to any enclosure length and depth, positioned by weight ballast, fluke or Platipus anchor to seabed. Components are chosen for durability, ease of installation and operation and minimal maintenance, such as strong and high buoyancy HDPE pipe float, marine grade Kikkonet skirting and stainless-steel connector. A manual gateway option allows marine traffic whenever necessary.
