Make your passage.

Take MERIDIAN through one of the busiest straits on Earth. Read the radar, keep to the eastbound lane, watch the echo sounder and reach the exit before the clock runs out.

Chat can join the ships standing in your way.

Your passage. Their strait.

Take MERIDIAN, a 262 m container ship drawing 13.2 m, eastbound through the Singapore Strait: from the Main Strait, round the turn into the Phillip Channel, past Buffalo Rock and Batu Berhanti, to the exit.

01 / TAKE THE HELM

← → turn; ↑ ↓ change speed. Heading and speed ease toward each order. The tidal stream sets you sideways: watch COG against your heading.

02 / READ THE RADAR

Click any echo to track it. CPA is the predicted closest distance; TCPA is game minutes to that point. Red means too close. Islands hide ships behind them; racon beacons paint their Morse letter behind the light.

03 / KEEP TO YOUR LANE

Stay in the eastbound lane. The separation zone and the westbound lane cost points and bring a call from Singapore VTIS. Fast ferries cross at Batu Berhanti.

04 / WATCH THE ECHO SOUNDER

Sand banks and reefs line the lanes. Speed makes the ship squat deeper: slow down in shallow water. Under 3 m below the keel the alarm sounds; at 0 m you are aground.

05 / LET CHAT IN

Connect Streamer.bot in Captain’s desk. Viewers use !join and steer their own traffic ship. With no viewers, automatic traffic keeps playing.

Coastline and depth bands are simplified from nautical charts; depths between contours are interpolated. Traffic lanes are approximate. This is an arcade game, not navigation equipment or a COLREG assessment.
