25. ock The boat has four fenders deployed Docks BoatMaster has three dock configurations that can be used to simulate most boat handling and docking situations The sizes of the docks are automatically adjusted to fit the size of the boat being simulated However a user can customize the size of any dock configuration All the configurations except the combination shown below can be rotated to four orientations 90 degrees apart The above is the default configuration and is a combination of a slip and a set of pilings The above configuration contains a standard slip and a side slip that is used to represent docking in a confined space such as between other boats at a wharf or a fuel dock The configuration above is simply a wharf and a set of pilings that can be found anywhere in the world The wharf when rotated so it is at the bottom can be used to simulate a beach when parking a houseboat It is also a good way to practice backing into a dock or sea wall off an anchor line as is often done in Europe Boats There are three boat types supported in BoatMaster motorboats sailboats and houseboats These boats are depicted in configurations that are typical classical forms These configurations are scaled to fit the sizes specified by the user and are shown below These boats all share graphics that are used to convey information to the user and to allow functions of the program to be used The dark gray dot near the

27. s Some people objected that BoatMaster wasn t game like Our response is that this program while fun and quite engaging is NOT a game and is intended to help its users make of themselves better and safer boaters Nonetheless I still love playing with it and if you find yourself being entertained as well well what s in a name Another objection was that you cannot learn boat handling on a simulator This is a use specific manifestation of an age old and old age complaint This has been disproven millions of times by tens of thousands of pilots who mastered multiple aircraft emergencies and routine operations using simulators As an experienced pilot and a very experienced boater I maintain that the only thing that you cannot do in a simulator is kill yourself or ruin your boat or airplane It is true that you cannot master the whole of boat handling or flying an airplane in a simulator but you can learn the procedures safely and economically BoatMaster is a true simulator It simulates the physics of boats and their interaction with the wind and water This new version allows multiple ways to configure the interactions of the boat and of the elemental forces of boating so it has an even more realistic feel Set up conflicting rapidly changing wind and current configurations and try putting your boat into a small slip between adjacent yachts and see if you don t find that challenge realistic We re betting you
