The RAmparts Class tugs are a series of proven, standardized Z-drive tug designs. Each of these designs has been developed from a successful prototype vessel or series of vessels, and refined to emphasize ease of construction. The primary target market for these designs are shipyards looking for proven, high-performance tug designs to offer to their Clients in response to direct enquiries, although many have also been offered directly to our tug operator Clients as well. These designs are available in fully developed steel part "kits", using ShipConstructor 3D modelling software.

The vessels are identified by length; e.g. RAmparts 3000, and there is a range of powers which can be accommodated within each. Each design is available in a typical ship-handling configuration, with a modest size of skeg, or in an "escort" configuration with a much deeper skeg for enhanced indirect steering force capability. All designs are available in metric dimensions, and some are also available in Imperial dimensions.

Currently the following RAmparts Class designs are available in fully developed design packages:

RAmparts 2400
RAmparts 2500
RAmparts 2800
RAmparts 3000
RAmparts 3200
