OckamSoft 5 addresses modern color graphics and the confluence of Ethernet, WiFi and Internet technologies, and the multiple devices that can exploit data from them. The display apps Race, EyeApp™ and Vysion™ are designed for different platforms, but all provide a consistent presentation of sailing data. You can run mutiple instances of them at the same time, and they will all work together.

Race is optimized for traditional PCs.
EyeApp™ (the mobile display app) is optimized for mobile devices.
Vysion™ (the embedded display) is optimized for fixed displays (e.g. mast displays).

These are all registered graphical display applications which show pages of data. See Pages for details.

How OS5 improves your racing knowledge and success

Graphical display format

As much as possible, OS5 displays information in graphical form. This condenses more data onto a single glance and makes vital information faster and easier to recognize and assimilate than numerics.

Starting line

Provides important information to improve your starting.

  • Accurate estimates of when you will cross the line.
  • Which end is favored and by how many seconds.
  • Where the wind is in its shift and puff range
  • And more…

Wind information

OS5 presents true wind in several formats that give you an instant knowledge of where the wind is in its shift and puff range (including active and left-right laylines), and geographically. There are also statistical outputs that include a measure of shift frequency, amplitude and trend. (Why true wind is so important)

An important factor in winning  is knowing how to take advantage of wind shifts. Here is a page that goes into the subject in more detail.

Performance monitoring

Winning means getting the most out of your boat at all times. If you don't know what that is, you have at least one hand tied behind your back. Polars are one of the keys to knowing. OS5 includes a polar page which shows you how you are doing rellative to your polars.

Remote Coach™

Support applicatios

Several other applications support the main applications of OS5.
Driver (free) Is the 'switchyard' and 'database slinger'. It is responsible for melding and distributing both live data (i.e. from the instruments), and 'static' data such as settings, registration and marks and courses. When an app pings a mark, it's the driver's job to tell all the other apps so they all remain in sync. Details are covered in the separate document OS5driver.pdf.
Is the startup application for OS5. It provides a single click method for starting any of the OS5 front line apps, and any other apps you choose.
Chart browser (registered) Is a ‘chart mower’ used to download charts for use by the display apps. The job can be done directly in a display app, but it is somewhat tedious. Chart browser is a lot easier. Details are covered in the separate document LoadingCharts.
SPedit (registered) Is the sail plan editor. You can access it from the Race prep/SailPlan tab of the driver. Details are covered in the separate documents SailPlanExplained and BuildingSailPlan.

Before you install OS5:
If you are unsure of the status of your computer's .NET framework, or are having trouble installing OS5, we recommend following these links (in order) to install the correct versions of the framework (versions 3.5 and 4 full packages),.

Note: Windows 7 steals port 5005 (the default UDP broadcast port)  for media streaming services.

.NET 3.5 SP1 framework install

.NET 4 framework install
If you have installed a previous version of OckamSoft 5, you will need to uninstall it before installing version 5.2.

Download OS5 (rev C304 8/27/13) (Windows MSI installer 16 Mb).
