RApport Series

The RApport designation describes a series of compact, flush-decked and cost-effective ASD tugs developed specifically for ship-handling in modern but typically smaller harbour and port operations. An example is the RApport 2400 MkII tug Signet Magic with 60 tonnes bollard pull.

The series is divided into four classes, each with a different design genesis but broadly the same capabilities; maximum power varies with tug size, and every class is under the 24 metre loadline rule length. One class is the CATES class, named for C.H. Cates and Sons of North Vancouver, an early client with whom Robert Allan Ltd. developed twin-screw and Z-drive ship-assist tugs for the Port of Vancouver from the 1960s; the later CATES tugs were among the first Z-drive tugs in North America.
