Rudder Effectiveness and Single I/O Prop Walk

Thanks to your suggestions we have added Rudder Effectiveness and Single I/O Prop Walk.

You can now select low/medium/high rudder effectiveness from the start menu. Be sure to refresh your browsers on the menu page and then again on the simulator page.

For a single I/O with an engine speed of 600 RPM, the engine in reverse, and the rudder turned hard port/starboard, the boat will move in the direction of the rudder.

Please let us know how the changes work for you.

Happy Boating!

Moving the boat to any starting position

Thanks to a suggestion from Ian, there is a new feature to position or reposition the boat when the simulator is STOPPED! Click on the boat to drag it anywhere on the screen (if you drag it out of bounds, nothing will work properly) and click on the wheel to change the heading of the boat. Refresh your browser and let us know how that works for you.

A New Look

Hello Boaters,

TheBoatDocker has a new look. Please let us know if you like it.

p.s.  There are many changes to many pages so if it does not work at first, refresh your browser in two different places: First refresh it at the opening menu page and then refresh it again at the running simulator page.

A New Release

We have just released a new version of the BoatDocker. Many of the changes are behind the scenes and we believe there are several subtle performance improvements. As always, please let us know how it works for you.

Updated Large Center Controls

Hello Boaters,

The Large Center Controls are now enabled from the startup menu and not by clicking in the water. This enables the user in the Man Overboard scenario to click on the new location of the MOB.


New Dock Configuration

Hello Boaters,

As you might have noticed, we have slightly modified the old dock configuration. More importantly, we have redesigned the system to rapidly add new dock configurations, which can then be selected from a startup menu.

So, we need your help! Send your dock configuration sketches to and we will try to implement them.
