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.

Verdict

The call

The clearest difference is review sentiment: Aviateur at 87% against OPYC's 20%. Aviateur also leads on rating (4.7 vs 2.6) and ratings volume (106 vs 8). OPYC's advantage is in-app purchases (none vs 13) and iOS requirement (11.0 vs 15.6). On price, update cadence, ads and device support there is nothing between them.
