Live traffic, marine weather, and a radar trainer.

Good passage decisions need the picture: where the traffic is, what the weather is doing on the route, and whether the tide gives a deep-draft hull the window it needs. Binnacle pulls live AIS, applies NOAA marine forecasts per route, and computes squat and under-keel clearance for confined water.

And because a sharp watch is the cheapest safety system there is, a browser-based PPI radar and ARPA simulator is built in for collision-avoidance practice — no hardware required.

Regulatory basis

Supports COLREGS collision-avoidance practice, ECDIS/radar watchkeeping under STCW, and the under-keel-clearance and squat considerations of confined-water pilotage.

What is included

Vessel tracking

Live AIS positions for the fleet and the traffic around it.

Weather routing

NOAA marine forecasts applied per route.

Forecasting

Wind, sea state, and visibility on the operating area.

Radar / ARPA simulator

A browser PPI radar trainer for collision-avoidance practice.

Squat & UKC

Squat and under-keel-clearance math for confined water.

Tide windows

Tide-gated transit windows from live NOAA predictions.

Questions

Where does the weather come from?

NOAA marine forecasts, applied along the route, plus wind, sea state, and visibility on the operating area.

Is the radar simulator real practice?

It is a browser-based PPI radar and ARPA trainer for collision-avoidance practice — useful for keeping a watch sharp without dedicated hardware.

Can I check a tide or squat figure for free?

Yes. The tide-window and squat calculators are free and need no login.
