Badass navigator, Disney Morning Light alum, and active-duty rescue pilot Chris Branning has been busy working in his spare time on something very cool for anyone who relies on GRIB files to cruise or race. It's an app that provides a way to significantly increase the accuracy of your GRIBs, and hence significantly decrease your time on a passage or around a race course. It's all hieroglyphics to a handle and rope monkey like me, but the details are here.
He's put together a page with useful links for navigators in Tuesday's St. Pete Havana Race and the Miami Havana Race in March over here.
He invited people using expedition to drop him a line on Facebook (or probably also via the contact form on the Model Accuracy website) to learn about the system his team has created to make you a winning navigator.
