Hi. My name is Omar Reis.

I'm developer of Navigator (
and VRTool ( softwares.

Navigator software includes celestial navigation, chart navigation
and star finder. VRTool is a subset of Navigator and was developed
to be used in virtual sailing games. It became popular among virtual sailors
as a tool for track planing and weather routing.

VRTool can download GFS wind forecasts directly from NOAA
servers, up to 384 hours. This is a free service from NOAA.
NOAA gribs are very compact files,
suitable for satellite internet limitations.

I'm also working on an iPhone app to work as a companion
software for VRTool desktop, called VRTool Sidekick (VSK)
It uses the phone GPS for real time sailing monitoring.

I will be participating in the ARC 13

Took a look and it looks very good - however I had three immediate problems:

- Finding the charts for the N. Atlantic was problematic

- The Grib download consistently failed (interrupted it said, then re-started, then the error re-occurred after several minutes, and on, and on)

- Importing other grib files (i.e. from Ugrib or Zygrib) returned an error saying could'nt find the highlighted file

Would like to take another look, but its a problem if some of the functions are problematic.
