Yacht & Boat Docking Simulator is free on Google Play

Yacht & Boat Docking Simulator usually costs $4.99 on Android and is free on Google Play for a limited time. It covers the hardest part of a boat trip, the last few minutes, when you have to ease a 10-meter yacht into its berth while dealing with momentum, wind and prop walk.

There are four harbors, based on Cala d'Or, Portofino, Kioni and Smögen. You can run a full harbor approach or a shorter docking drill, from a chase camera or the helm view. After each attempt you get docking feedback and a skipper rating, and runs go into a logbook. It works offline, with no ads and no account.

If you like slow, precise sims, it's an easy pick. Claim it while it's free and it stays in your Google Play library after the offer ends. No end date has been announced.
