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.

Experience what it really takes to handle a large ship. Ship Maneuvering Simulator is built on the MMG hydrodynamic model, the same kind of model used in professional ship handling research, so every ship drifts, pivots and answers the helm the way the real thing does. Made by a professional maritime pilot who handles large ships every day, and tuned to feel like the real thing, but built to be fun: time runs faster than real life, so you get to the challenge quickly. CAREER MODE • Start as Cadet and earn your stripes, rank by rank, up to Captain and Pilot • Real ship handling missions: buoyed channels, stopping, turning, going astern, anchoring, holding position in wind and current, berthing alongside, entering a lock and leaving the quay with tugs • Earn up to 3 stars per mission and unlock new ships • Weekly and all-time leaderboards for every mission, so you can compete with players worldwide 8 SHIPS, EACH WITH ITS OWN CHARACTER Cargo ship, navy supply ship, loaded and empty bulker, large container ship, cruise ship, frigate and battleship. Each has its own engine, speed and handling, from a slow loaded bulker to a 28-knot frigate. REALISTIC HANDLING • Propeller walk when going astern • Drift in turns and a pivot point that moves with speed • Rudder effect that depends on propeller wash and speed • Bow thruster that loses power as speed builds • Realistic stopping distances and turning circles • Wind and current that set you off your course • Tugs that push and pull for berthing and unberthing FREE PLAY Take any unlocked ship out at sea, on the river or in port. Set the wind and current yourself and practise at your own pace. SOUND AND LOOK An engine sound for each ship (twin engines, frigate gas turbines), bow thruster, tugs, collisions and a busy harbour. Whether you're a seafarer, a maritime student or just love ships, see if you have what it takes to bring her alongside without a scratch.

Verdict

The call

The clearest difference is review sentiment: Ship Maneuvering Simulator at 86% against OPYC's 20%. Ship Maneuvering Simulator also leads on rating (4.3 vs 2.6) and update cadence (every 6 days vs every 3 months). OPYC's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, in-app purchases and device support there is nothing between them.
