This completely redesigned 3D Version of the famous App "Dock Your Boat" offers even greater enjoyment of training because of its advanced user-friendly functions and beautiful artwork. The developers are passionate skippers by themselves and bring their sailing experience into the game. The basic concept behind Dock your Boat 3D is the same as for the first 2D Version: The boat and harbour-simulator for docking and undocking under engine helps the skipper to improve her/his skills in safe manoeuvring of yachts in different environments. It also allows to handle lines, fenders and anchor. The wind strength can be set individually depending upon desired degree of difficulty. If you want to play all scenes you will have to purchase a subscription. You will get access to all existing and future scenes then. From now on you can also design your own scenes and share with your friends or students. We offer several subscription models ranging from 1 week to 1 year. The price is shown inside the app since it slightly varies for different countries. Payment will be charged to your Apple ID account at the confirmation of purchase. The subscription automatically renews unless it is canceled at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period. You can manage and cancel your subscriptions by going to your App Store account settings after purchase. Terms of Service: http://dyb3d.sfinx-it.com/eula Privacy Policy: http://dyb3d.sfinx-it.com/about Should also work on older devices back to 2015! Recommendation: Make sure the app can access the internet on the first run! It should download scenes and other configurations that might be specific for your device. After that network is not needed anymore. However you will not get any configuration updates or new scenes then! You might have to tap the "Factory reset" button on the start screen, if you encounter problems.
