RApide SERIES

For many decades Robert Allan Ltd. has designed tugs, barges and other specialized workboats for the shallow waters of Canada’s northland. The expertise gained in designing for this very challenging environment has provided opportunities with projects in other parts of the globe where similar (if generally warmer!) conditions prevail. The result is a significant portfolio of very specialized, extreme shallow draft pusher tugs, designated as the RApide series.

RApide tugs can be propelled by dual (2), triple (3) or quadruple (4) conventional screws (S), Z-drives (Z), or in some cases of extreme shallow draft by water jets (J). The RApide series tugs are designated by length, propulsion type, and number of screws; e.g. RApide 4500-Z4.

Series Features

  • Enhanced shallow-draft pusher tug designs for major river transportation systems
  • Decades of extreme shallow draft vessel design experience melded with modern CFD analytical capabilities for maximum performance
  • Available in twin, triple, and quadruple screw configurations, with conventional or Z-drive propulsion
