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.
▤ POSTER shows a vessel's manoeuvring data the way a ship's wheelhouse poster does: turning circles, stopping distances, the propeller's effect, the thrusters and the speed for each engine order. The figures are measured on the simulator's own physics, so they match how she handles here, and any other vessel can be picked to compare.
Every bow and stern thruster now has the force of a real installation for that vessel, taken from the makers' published data: weaker than before on the 15 m motor yacht and the B.Yond 40M, stronger on the tanker and the cruise ship. Boats that have no thrusters in real life have none here either.
Stopped or at a crawl the wind now blows her off the way her shape says: a sailing yacht's bow falls off first, a motor yacht's stern. Going astern the screw kicks her stern, twin screws split ahead and astern turn her on the spot, and the thrusters spool up and fade with speed; under way and under sail she handles as before.
The docking plan is drawn like a pilot book's marina plan: clean and north up, with graded contacts, her navigation lights at night and the thrusters shown in colour. Depth no longer slows or stops her: the water is deep everywhere and only the shore stops her.
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.
