The Columbia/Deschutes
Sea-Going Hovercraft

The Columbia was designed in response to a client's request for a "close to shore" sea-going personnel and equipment transport.

Features of "Columbia"

  1. This medium-sized hovercraft was designed to operate in Beaufort 4 sea conditions (waves of 1 to 4 feet).
  2. In order to provide a high mission reliability, the "Columbia" was designed with twin propulsion engines, twin lift engines and also a bow thruster which enables the pilot to steer the craft with precision at low forward speeds.
  3. Reversible propellers enable the pilot to back up.
  4. The skirt was designed with an inflatable bag section and a "finger skirt" section to enable operation in choppy wave conditions; the finger skirt sections may be individually replaced, thereby enhancing skirt maintenance.
  5. Inflated skirt provides a resilient bumper for safe approach and docking against hard structures such as docks, ships and oilrigs.
  6. The cabin is designed to be fitted out with 12 aircraft-style passenger seats, and has provision for two crew. An equipment/baggage enclosure is provided, with a capacity of 1/2 ton.
  7. For inland waters, the cabin has the capacity to seat twenty or more passengers, plus two crew. A lavatory is provided in either case.
  8. The raised prow was designed to split any oncoming waves and to ensure that the water pressure load imposed upon the cabin structure is minimized; waves will be deflected out and downwards.
  9. A range of 190 nautical miles (220 statute miles, 350 kilometres) is provided.

The Deschutes was designed as a lower budget alternative to the sea-going "Columbia" hovercraft.

Features of "Deschutes"

  1. This medium-sized hovercraft was designed to operate in Beaufort 3 sea conditions (waves of up to 1 foot).
  2. The "Deschutes" was designed with one propulsion engine and one lift engine.
  3. A reversible propeller can enable the pilot to back up.
  4. The skirt was designed with an inflatable bag section and a "finger skirt" section to enable operation in choppy wave conditions; the finger skirt sections may be individually replaced, thereby enhancing skirt maintenance.
  5. Inflated skirt provides a resilient bumper for safe approach and docking against hard structures such as docks, ships and oilrigs.
  6. The cabin is designed to be fitted out with 12 aircraft-style passenger seats, and has provision for two crew. An equipment/baggage enclosure is provided, with a capacity of 1/2 ton.
  7. For inland waters, the cabin has the capacity to seat twenty or more passengers, plus two crew. A lavatory is provided in either case.
  8. The raised prow was designed to split any oncoming waves and to ensure that the water pressure load imposed upon the cabin structure is minimized; waves will be deflected out and downwards.
  9. A range of 200 nautical miles (230 statute miles, 370 kilometres) is provided.
  10. Oregon Hovercraft will outfit the craft with any necessary radio and navigation equipment, per client requirements.
