RAstar SERIES

The RAstar escort/offshore terminal tug designation is reserved for a distinctive class of very high-performance ASD tugs, designed with the unique sponsoned hull form developed exclusively by Robert Allan Ltd., which has been proven in both model and full-scale testing to provide significantly enhanced escort towing performance. Escort forces are enhanced by the effects of the sponsons as well as by the prominent foil-shaped escort skeg forward.

RAstar tugs will typically be high-powered, intended for demanding escort operations in exposed areas.

RAstar series tugs are classified according to their approximate length, e.g. RAstar 3400 (34 metres length), and a range of powers can be accommodated within each hull size according to the specific operational needs. Accordingly there may be beam variations with the same length.

Series Features

  • The epitome of high-performance ASD escort tugs
  • Unique sponsoned hull-form for superior escort performance and improved sea-keeping
