This completely redesigned 3D Version of the famous App "Dock Your Boat" offers even greater enjoyment of training because of its advanced user-friendly functions and beautiful artwork. The developers are passionate skippers by themselves and bring their sailing experience into the game. The basic concept behind Dock your Boat 3D is the same as for the first 2D Version: The boat and harbour-simulator for docking and undocking under engine helps the skipper to improve her/his skills in safe manoeuvring of yachts in different environments. It also allows to handle lines, fenders and anchor. The wind strength can be set individually depending upon desired degree of difficulty.

Recommendation: Make sure the app can access the internet on the first run! It should download scenes and other configurations that might be specific for your device. After that network is not needed anymore. However you will not get any configuration updates or new scenes then! You might have to tap the "Factory reset" button on the start screen, if you encounter problems.

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.
