About this app
This simulator will give you a realistic experience of what it's like to handle a large ship. It includes some features which often seem to be missing in other simulators: - Astern effect of the propeller - Drift during turn - Pivot point movement - Rudder effectiveness based on propeller flow and ship's own velocity - Bow thruster effectiveness influenced by ship's velocity For the moment there are three ships (cargo ship, supply ship and battle ship). In the future more may be added. The game is played in a sandbox style with a sea, river and port environment and customisable current. I plan to also add wind effect. The simulation is based on the mathematical hydrodynamic MMG model which is also used in professional ship handling and mooring simulators.
Latest release
What’s New
- All-new low-speed professional MMG handling model based on new research (Taniguchi & Maki, 2025) for even more realistic harbour manoeuvring, proper drift, propeller "walk", pivot point movement and rudder/propeller behaviour. - Added tug assistance: control the tugs in lateral (push/pull) or longitudinal (bow/stern tug) mode to help you berth and unberth (available only on the Cargo Ship for now). - Improved wind model - Various handling and stability refinements. - Fixed timescale button
