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.
The RApport series are divided into four classes of tug, each representing a different design genesis but all offering broadly the same capabilities, although the maximum power in each class varies as a function of tug size. Each of these classes is under the 24 metre Loadline rule length.
One of these classes of tugs is designated as the CATES class, paying tribute to C.H. Cates and Sons of North Vancouver, one of our earliest major clients and a company with whom we collaborated very closely in the early development of a significant series of twin-screw and Z-drive ship-assist tugs for the Port of Vancouver over more than a twenty year period beginning in the 1960’s. The later CATES tugs were amongst the first Z-drive tugs in North America. Derivatives of these designs led to some of our earliest export contracts. The lessons learned from working with the fine people involved with this innovative and forward thinking organization (now part of the Washington Marine Group) led the way to our successful expansion into the worldwide business of ship-assist tug design. The CATES class tugs are characterized by their light displacement, simple and cost-effective outfitting and construction, and “slippery” hull form, ideal for fast manoeuvring, fast side-slip, and rapid response.
RApport tugs are typically designed in an ASD configuration, but some are also twin-screw, designated by a TS suffix.
