OPYC vs Ship Maneuvering Simulator

OPYC* is a worldwide sailing simulation using physics. The game runs locally on your device, using laws of physics. It is different from other web sailing games that run on a server, whether you are actively sailing or not. This allows the game to be more like real sailing, with waves, Chinese jibes, flapping sails and unexpected situations. Go out of control in strong winds. Its quantum sailing. The simulation uses real wind forecasts from NOAA GFS. Interpolated real time winds ( 144h forecast, 3 hour interval ). VRTool chart tool embedded. Download wind grid and perform weather routing optimizations. Draw routes and tracks. Add marks. Manage chart objects. To participate, you have to register a boat name, skipper name, password and choose a port to start from. May be used in multiple devices. Last device connecting has the key. Use boat name and password to login. Earn OPYC coins by finding and crossing gates around the world (currently gates only in North, South, Central Americas and Europe). You can also select a venue and create a race (triangle or linear course). Create a regatta and invite your friends to participate. The new 3D view brings immersive sailing challenges, with sea waves, dynamic sail shapes, oscillating wind arrow and other characters. * OPYC, short for Old Pelican Yacht Club, since 2018 serving the virtual sailing community with navigation software and weather forecasts.

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.
