Every release of the SkipperCheck COLREG and ship-handling simulator, newest first: what changed, in plain words, and a link that opens it straight in the simulator.
AREA → CROATIA · CENTRAL DALMATIA: Split, Trogir, Šolta, Brač, Hvar and the Pakleni islands, Vis and the Makarska riviera, with 174 harbours, coves and buoy fields, ferries on their real routes and the area's real forecast wind. With a simulator plan you start inside a harbour on the detailed chart and can dock there; without one you start at the harbour's approach.
The compass, COG, radar and docking plan now agree with the real chart anywhere in the Baltic: true north within 0.05°, where it had been up to 11° out in the west. The wind and weather are MET Norway's forecast for where she is, blended from sea points around her.
With Marine Simulator Training or the Skipper Refresher Course the Baltic from the Gulf of Bothnia to Kiel, the Belts and the Kattegat streams in detail as you sail, and you can start inside, enter and dock in about 2,000 harbours. Without a plan the rest of the Baltic stays a coarse chart, with starts at each harbour's approach.
The harbour picker lists about 1,800 harbours round the whole Baltic, searchable by name or country, and starts her at the chosen harbour's approach, heading out to open water.
Past the Gulf of Riga the coasts and islands of the whole Baltic (Gotland, Öland, Bornholm, the Estonian islands, the archipelagos, the Gulfs of Finland and Bothnia and the Danish straits) are now in the chart, the radar and the 3-D view, with the major lights.
Free Mode is free for everyone, with no account. The shared sea and regattas need a free SkipperCheck account. The detailed Baltic and Croatian charts and every docking lesson come with Marine Simulator Training or the Skipper Refresher Course. The simulator is a training tool, not a navigation product.
