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.

Draw safe routes. Guide ships to dock. Keep the harbor moving. Harbor King is a real-time ship traffic game that puts you in charge of a busy port. Draw a path for each boat, guide it to the correct dock to unload, then send it safely back out to sea. Watch every route: one collision can disrupt your run. DRAW, DOCK AND DEPART • Guide small boats and large cargo ships by drawing lines across the water. • Bring each vessel to the right dock to unload its cargo. • Keep dock entrances clear and plan around ships already on the move. • Lead ships out of the harbor once unloading is complete. KEEP TRAFFIC UNDER CONTROL As more vessels arrive, routes cross and dock space becomes limited. Plan ahead, react quickly and manage several ships at once. Different boats bring different handling challenges, making timing and route planning essential. COLLECT COINS AND CONTINUE YOUR RUN Draw through coin lines to collect coins along your route. Spin the daily wheel for additional rewards, then use coins to buy extra lives and continue after a mistake. QUICK ROUNDS, GROWING CHALLENGES Harbor King combines route drawing, time management and fast decisions in short play sessions. Each arrival gives you another path to plan and another collision to avoid. Take charge of the port and guide every ship safely home.
