A minor bug in the graphics for the sailing velocity prediction program has been fixed. The true wind and apparent wind vector angles were not being plotted correctly. The angles on the plots should now match the angles entered or computed.
A basic velocity prediction program (VPP) has been released. The code was developed as a teaching tool to help beginning sailors understand the influence of a number of parameters on boat speed and performance. The code is compiled for the Windows operating system and available under the Computer Codes link. For further information the user should refer to the Help menu within the code.
